If Button Is Clicked Dont Do Action Again Jquery
JavaScript
Bring Bootstrap's components to life with over a dozen custom jQuery plugins. Easily include them all, or one past 1.
Individual or compiled
Plugins tin be included individually (using Bootstrap'south individual *.js files), or all at once (using bootstrap.js or the minified bootstrap.min.js).
Using the compiled JavaScript
Both bootstrap.js and bootstrap.min.js comprise all plugins in a single file. Include only one.
Plugin dependencies
Some plugins and CSS components depend on other plugins. If y'all include plugins individually, brand sure to check for these dependencies in the docs. Likewise notation that all plugins depend on jQuery (this ways jQuery must be included earlier the plugin files). Consult our bower.json to come across which versions of jQuery are supported.
Data attributes
Y'all tin utilize all Bootstrap plugins purely through the markup API without writing a unmarried line of JavaScript. This is Bootstrap'southward first-course API and should be your first consideration when using a plugin.
That said, in some situations it may exist desirable to turn this functionality off. Therefore, we besides provide the ability to disable the data attribute API by unbinding all events on the document namespaced with data-api. This looks like this:
$ ( document ). off ( '.data-api' ) Alternatively, to target a specific plugin, only include the plugin's name as a namespace along with the data-api namespace like this:
$ ( document ). off ( '.alarm.information-api' ) Only one plugin per element via data attributes
Don't use data attributes from multiple plugins on the aforementioned chemical element. For case, a button cannot both have a tooltip and toggle a modal. To accomplish this, utilise a wrapping chemical element.
Programmatic API
We also believe y'all should be able to utilize all Bootstrap plugins purely through the JavaScript API. All public APIs are unmarried, chainable methods, and return the collection acted upon.
$ ( '.btn.danger' ). button ( 'toggle' ). addClass ( 'fat' ) All methods should have an optional options object, a cord which targets a particular method, or cypher (which initiates a plugin with default behavior):
$ ( '#myModal' ). modal () // initialized with defaults $ ( '#myModal' ). modal ({ keyboard : false }) // initialized with no keyboard $ ( '#myModal' ). modal ( 'bear witness' ) // initializes and invokes testify immediately Each plugin likewise exposes its raw constructor on a Constructor property: $.fn.popover.Constructor. If y'all'd similar to get a item plugin instance, retrieve it directly from an element: $('[rel="popover"]').data('popover').
Default settings
You lot can change the default settings for a plugin by modifying the plugin's Constructor.DEFAULTS object:
$ . fn . modal . Constructor . DEFAULTS . keyboard = fake // changes default for the modal plugin's `keyboard` option to false No conflict
Sometimes information technology is necessary to utilise Bootstrap plugins with other UI frameworks. In these circumstances, namespace collisions tin occasionally occur. If this happens, you may telephone call .noConflict on the plugin y'all wish to revert the value of.
var bootstrapButton = $ . fn . push . noConflict () // return $.fn.push to previously assigned value $ . fn . bootstrapBtn = bootstrapButton // give $().bootstrapBtn the Bootstrap functionality Events
Bootstrap provides custom events for most plugins' unique actions. Mostly, these come in an infinitive and past participle form - where the infinitive (ex. show) is triggered at the start of an upshot, and its by participle form (ex. shown) is triggered on the completion of an activity.
As of 3.0.0, all Bootstrap events are namespaced.
All infinitive events provide preventDefault functionality. This provides the ability to stop the execution of an action before it starts.
$ ( '#myModal' ). on ( 'show.bs.modal' , office ( e ) { if ( ! data ) return e . preventDefault () // stops modal from existence shown }) Sanitizer
Tooltips and Popovers utilize our built-in sanitizer to sanitize options which accept HTML.
The default whiteList value is the post-obit:
var ARIA_ATTRIBUTE_PATTERN = /^aria- [\w - ] *$/i var DefaultWhitelist = { // Global attributes immune on any supplied element beneath. '*' : [ 'form' , 'dir' , 'id' , 'lang' , 'role' , ARIA_ATTRIBUTE_PATTERN ], a : [ 'target' , 'href' , 'title' , 'rel' ], area : [], b : [], br : [], col : [], code : [], div : [], em : [], 60 minutes : [], h1 : [], h2 : [], h3 : [], h4 : [], h5 : [], h6 : [], i : [], img : [ 'src' , 'alt' , 'title' , 'width' , 'summit' ], li : [], ol : [], p : [], pre : [], s : [], small : [], span : [], sub : [], sup : [], strong : [], u : [], ul : [] } If yous want to add together new values to this default whiteList you tin do the following:
var myDefaultWhiteList = $ . fn . tooltip . Constructor . DEFAULTS . whiteList // To permit table elements myDefaultWhiteList . table = [] // To permit td elements and data-option attributes on td elements myDefaultWhiteList . td = [ 'data-option' ] // You can button your custom regex to validate your attributes. // Be conscientious most your regular expressions beingness too lax var myCustomRegex = /^data-my-app- [\w - ] +/ myDefaultWhiteList [ '*' ]. push button ( myCustomRegex ) If you want to bypass our sanitizer because you prefer to use a dedicated library, for example DOMPurify, you should practice the following:
$ ( '#yourTooltip' ). tooltip ({ sanitizeFn : function ( content ) { return DOMPurify . sanitize ( content ) } }) Browsers without document.implementation.createHTMLDocument
In instance of browsers that don't support document.implementation.createHTMLDocument, like Internet Explorer eight, the built-in sanitize function returns the HTML as is.
If yous want to perform sanitization in this instance, delight specify sanitizeFn and apply an external library like DOMPurify.
Version numbers
The version of each of Bootstrap's jQuery plugins tin can be accessed via the VERSION holding of the plugin'southward constructor. For example, for the tooltip plugin:
$ . fn . tooltip . Constructor . VERSION // => "3.iv.i" No special fallbacks when JavaScript is disabled
Bootstrap's plugins don't autumn back specially gracefully when JavaScript is disabled. If yous care nearly the user experience in this case, utilize <noscript> to explain the state of affairs (and how to re-enable JavaScript) to your users, and/or add your ain custom fallbacks.
Third-political party libraries
Bootstrap does not officially support third-party JavaScript libraries similar Paradigm or jQuery UI. Despite .noConflict and namespaced events, there may exist compatibility problems that you demand to fix on your own.
About transitions
For simple transition effects, include transition.js in one case alongside the other JS files. If y'all're using the compiled (or minified) bootstrap.js, there is no need to include this—it'due south already in that location.
What'south inside
Transition.js is a basic helper for transitionEnd events also as a CSS transition emulator. It's used by the other plugins to check for CSS transition support and to grab hanging transitions.
Disabling transitions
Transitions can be globally disabled using the following JavaScript snippet, which must come after transition.js (or bootstrap.js or bootstrap.min.js, equally the case may be) has loaded:
$ . support . transition = false Modals are streamlined, but flexible, dialog prompts with the minimum required functionality and smart defaults.
Multiple open up modals non supported
Be sure not to open up a modal while another is withal visible. Showing more than one modal at a fourth dimension requires custom code.
Modal markup placement
Always try to place a modal's HTML code in a top-level position in your document to avoid other components affecting the modal's advent and/or functionality.
Due to how HTML5 defines its semantics, the autofocus HTML attribute has no effect in Bootstrap modals. To achieve the same outcome, use some custom JavaScript:
$ ( '#myModal' ). on ( 'shown.bs.modal' , function () { $ ( '#myInput' ). focus () }) Examples
Static example
A rendered modal with header, body, and set of actions in the footer.
<div grade= "modal fade" tabindex= "-ane" part= "dialog" > <div class= "modal-dialog" role= "document" > <div class= "modal-content" > <div grade= "modal-header" > <button type= "button" class= "close" data-dismiss= "modal" aria-characterization= "Shut" ><bridge aria-subconscious= "true" > × </span></button> <h4 class= "modal-title" >Modal title</h4> </div> <div course= "modal-body" > <p>One fine body… </p> </div> <div class= "modal-footer" > <button type= "button" form= "btn btn-default" data-dismiss= "modal" >Close</button> <button type= "button" grade= "btn btn-primary" >Salve changes</push button> </div> </div> <!-- /.modal-content --> </div> <!-- /.modal-dialog --> </div> <!-- /.modal --> Live demo
Toggle a modal via JavaScript by clicking the button beneath. It volition slide down and fade in from the meridian of the folio.
<!-- Button trigger modal --> <push button blazon= "button" class= "btn btn-primary btn-lg" information-toggle= "modal" data-target= "#myModal" > Launch demo modal </button> <!-- Modal --> <div form= "modal fade" id= "myModal" tabindex= "-one" function= "dialog" aria-labelledby= "myModalLabel" > <div class= "modal-dialog" function= "document" > <div class= "modal-content" > <div class= "modal-header" > <button blazon= "button" class= "close" data-dismiss= "modal" aria-characterization= "Close" ><span aria-hidden= "true" > × </span></push> <h4 class= "modal-title" id= "myModalLabel" >Modal championship</h4> </div> <div course= "modal-body" > ... </div> <div class= "modal-footer" > <button type= "button" class= "btn btn-default" data-dismiss= "modal" >Close</push> <push button blazon= "button" class= "btn btn-primary" >Save changes</push> </div> </div> </div> </div> Make modals accessible
Be sure to add role="dialog" and aria-labelledby="...", referencing the modal championship, to .modal, and role="certificate" to the .modal-dialog itself.
Additionally, you may give a description of your modal dialog with aria-describedby on .modal.
Embedding YouTube videos
Embedding YouTube videos in modals requires additional JavaScript not in Bootstrap to automatically stop playback and more. Run into this helpful Stack Overflow mail service for more information.
Optional sizes
Modals take 2 optional sizes, available via modifier classes to be placed on a .modal-dialog.
<!-- Large modal --> <push button type= "push button" class= "btn btn-primary" data-toggle= "modal" data-target= ".bs-example-modal-lg" >Large modal</button> <div class= "modal fade" tabindex= "-one" function= "dialog" aria-labelledby= "myLargeModalLabel" > <div class= "modal-dialog modal-lg" role= "document" > <div form= "modal-content" > ... </div> </div> </div> <!-- Pocket-sized modal --> <button type= "button" class= "btn btn-primary" information-toggle= "modal" information-target= ".bs-instance-modal-sm" >Small modal</push> <div grade= "modal fade" tabindex= "-1" role= "dialog" aria-labelledby= "mySmallModalLabel" > <div grade= "modal-dialog modal-sm" role= "certificate" > <div class= "modal-content" > ... </div> </div> </div> Remove animation
For modals that just announced rather than fade in to view, remove the .fade class from your modal markup.
<div form= "modal" tabindex= "-one" role= "dialog" aria-labelledby= "..." > ... </div> Using the grid system
To have advantage of the Bootstrap filigree organisation inside a modal, just nest .rows inside the .modal-body and so apply the normal grid system classes.
<div class= "modal fade" tabindex= "-ane" role= "dialog" aria-labelledby= "gridSystemModalLabel" > <div class= "modal-dialog" role= "certificate" > <div form= "modal-content" > <div class= "modal-header" > <push blazon= "button" form= "close" data-dismiss= "modal" aria-characterization= "Close" ><span aria-hidden= "true" > × </bridge></push button> <h4 class= "modal-title" id= "gridSystemModalLabel" >Modal championship</h4> </div> <div class= "modal-torso" > <div class= "row" > <div class= "col-md-4" >.col-doc-4</div> <div grade= "col-md-4 col-md-offset-4" >.col-md-iv .col-doc-offset-iv</div> </div> <div form= "row" > <div form= "col-md-iii col-doc-offset-3" >.col-md-three .col-doctor-starting time-3</div> <div course= "col-md-2 col-md-outset-4" >.col-md-2 .col-physician-offset-four</div> </div> <div class= "row" > <div class= "col-md-6 col-md-offset-3" >.col-dr.-6 .col-dr.-offset-3</div> </div> <div class= "row" > <div class= "col-sm-9" > Level ane: .col-sm-ix <div course= "row" > <div course= "col-xs-viii col-sm-6" > Level 2: .col-xs-8 .col-sm-6 </div> <div form= "col-xs-4 col-sm-half-dozen" > Level two: .col-xs-4 .col-sm-vi </div> </div> </div> </div> </div> <div class= "modal-footer" > <push button type= "button" class= "btn btn-default" data-dismiss= "modal" >Close</button> <button type= "button" class= "btn btn-chief" >Salve changes</button> </div> </div> <!-- /.modal-content --> </div> <!-- /.modal-dialog --> </div> <!-- /.modal --> Take a bunch of buttons that all trigger the aforementioned modal, merely with slightly different contents? Apply event.relatedTarget and HTML information-* attributes (perchance via jQuery) to vary the contents of the modal depending on which push button was clicked. Run across the Modal Events docs for details on relatedTarget,
<button type= "button" class= "btn btn-principal" information-toggle= "modal" data-target= "#exampleModal" information-whatever= "@mdo" >Open up modal for @mdo</button> <button type= "button" grade= "btn btn-primary" information-toggle= "modal" information-target= "#exampleModal" data-whatever= "@fat" >Open modal for @fat</push> <button type= "push" class= "btn btn-primary" data-toggle= "modal" information-target= "#exampleModal" information-whatsoever= "@getbootstrap" >Open modal for @getbootstrap</push> ...more buttons... <div course= "modal fade" id= "exampleModal" tabindex= "-ane" part= "dialog" aria-labelledby= "exampleModalLabel" > <div form= "modal-dialog" office= "document" > <div class= "modal-content" > <div class= "modal-header" > <push button blazon= "push button" grade= "close" information-dismiss= "modal" aria-label= "Close" ><span aria-hidden= "true" > × </span></push button> <h4 class= "modal-title" id= "exampleModalLabel" >New bulletin</h4> </div> <div form= "modal-body" > <form> <div course= "form-group" > <characterization for= "recipient-name" form= "control-label" >Recipient:</label> <input type= "text" class= "form-control" id= "recipient-proper noun" > </div> <div class= "form-group" > <label for= "message-text" class= "command-characterization" >Message:</label> <textarea form= "course-control" id= "message-text" ></textarea> </div> </form> </div> <div class= "modal-footer" > <button type= "button" class= "btn btn-default" data-dismiss= "modal" >Shut</button> <button blazon= "button" class= "btn btn-primary" >Send message</button> </div> </div> </div> </div> $ ( '#exampleModal' ). on ( 'show.bs.modal' , function ( issue ) { var button = $ ( consequence . relatedTarget ) // Button that triggered the modal var recipient = button . data ( 'whatever' ) // Excerpt info from data-* attributes // If necessary, you could initiate an AJAX request here (and so do the updating in a callback). // Update the modal'south content. Nosotros'll apply jQuery here, but you lot could use a data binding library or other methods instead. var modal = $ ( this ) modal . observe ( '.modal-title' ). text ( 'New bulletin to ' + recipient ) modal . observe ( '.modal-body input' ). val ( recipient ) }) Usage
The modal plugin toggles your subconscious content on demand, via data attributes or JavaScript. It also adds .modal-open to the <body> to override default scrolling behavior and generates a .modal-properties to provide a click area for dismissing shown modals when clicking outside the modal.
Via information attributes
Activate a modal without writing JavaScript. Ready data-toggle="modal" on a controller element, like a button, along with a information-target="#foo" or href="#foo" to target a specific modal to toggle.
<button type= "push" data-toggle= "modal" data-target= "#myModal" >Launch modal</push button> Via JavaScript
Call a modal with id myModal with a single line of JavaScript:
$ ( '#myModal' ). modal ( options ) Options
Options can exist passed via information attributes or JavaScript. For data attributes, append the choice name to data-, equally in information-backdrop="".
| Name | blazon | default | clarification |
|---|---|---|---|
| backdrop | boolean or the string 'static' | true | Includes a modal-properties chemical element. Alternatively, specify static for a properties which doesn't close the modal on click. |
| keyboard | boolean | truthful | Closes the modal when escape key is pressed |
| show | boolean | true | Shows the modal when initialized. |
| remote | path | false | This option is deprecated since v3.3.0 and has been removed in v4. We recommend instead using client-side templating or a data binding framework, or calling jQuery.load yourself. If a remote URL is provided, content will be loaded 1 time via jQuery's |
Methods
.modal(options)
Activates your content every bit a modal. Accepts an optional options object.
$ ( '#myModal' ). modal ({ keyboard : false }) .modal('toggle')
Manually toggles a modal. Returns to the caller before the modal has actually been shown or subconscious (i.due east. before the shown.bs.modal or hidden.bs.modal result occurs).
$ ( '#myModal' ). modal ( 'toggle' ) .modal('testify')
Manually opens a modal. Returns to the caller before the modal has actually been shown (i.east. before the shown.bs.modal event occurs).
$ ( '#myModal' ). modal ( 'evidence' ) .modal('hibernate')
Manually hides a modal. Returns to the caller before the modal has actually been hidden (i.e. earlier the hidden.bs.modal event occurs).
$ ( '#myModal' ). modal ( 'hide' ) .modal('handleUpdate')
Readjusts the modal's positioning to counter a scrollbar in instance i should appear, which would make the modal leap to the left.
Only needed when the elevation of the modal changes while information technology is open.
$ ( '#myModal' ). modal ( 'handleUpdate' ) Events
Bootstrap'due south modal class exposes a few events for hooking into modal functionality.
All modal events are fired at the modal itself (i.due east. at the <div class="modal">).
| Outcome Type | Description |
|---|---|
| show.bs.modal | This event fires immediately when the evidence instance method is called. If caused by a click, the clicked element is available as the relatedTarget property of the effect. |
| shown.bs.modal | This event is fired when the modal has been made visible to the user (will look for CSS transitions to complete). If caused by a click, the clicked element is available as the relatedTarget property of the event. |
| hide.bs.modal | This consequence is fired immediately when the hide instance method has been chosen. |
| hidden.bs.modal | This event is fired when the modal has finished beingness hidden from the user (will wait for CSS transitions to consummate). |
| loaded.bs.modal | This event is fired when the modal has loaded content using the remote option. |
$ ( '#myModal' ). on ( 'subconscious.bs.modal' , role ( east ) { // practise something... }) Examples
Add together dropdown menus to nearly annihilation with this simple plugin, including the navbar, tabs, and pills.
Within a navbar
Within pills
Usage
Via data attributes or JavaScript, the dropdown plugin toggles subconscious content (dropdown menus) by toggling the .open class on the parent list item.
On mobile devices, opening a dropdown adds a .dropdown-backdrop equally a tap area for closing dropdown menus when tapping outside the menu, a requirement for proper iOS support. This means that switching from an open dropdown menu to a different dropdown carte du jour requires an actress tap on mobile.
Note: The data-toggle="dropdown" attribute is relied on for closing dropdown menus at an application level, so it's a good thought to always use it.
Via data attributes
Add together information-toggle="dropdown" to a link or push button to toggle a dropdown.
<div class= "dropdown" > <button id= "dLabel" type= "button" information-toggle= "dropdown" aria-haspopup= "true" aria-expanded= "false" > Dropdown trigger <span class= "caret" ></span> </button> <ul form= "dropdown-bill of fare" aria-labelledby= "dLabel" > ... </ul> </div> To continue URLs intact with link buttons, use the data-target aspect instead of href="#".
<div class= "dropdown" > <a id= "dLabel" data-target= "#" href= "http://case.com/" data-toggle= "dropdown" office= "push" aria-haspopup= "truthful" aria-expanded= "faux" > Dropdown trigger <span class= "caret" ></span> </a> <ul grade= "dropdown-menu" aria-labelledby= "dLabel" > ... </ul> </div> Via JavaScript
Call the dropdowns via JavaScript:
$ ( '.dropdown-toggle' ). dropdown () data-toggle="dropdown" notwithstanding required
Regardless of whether y'all call your dropdown via JavaScript or instead utilise the data-api, data-toggle="dropdown" is always required to be present on the dropdown's trigger element.
Options
None
Methods
$().dropdown('toggle')
Toggles the dropdown menu of a given navbar or tabbed navigation.
Events
All dropdown events are fired at the .dropdown-carte's parent element.
All dropdown events take a relatedTarget holding, whose value is the toggling anchor element.
| Event Type | Description |
|---|---|
| show.bs.dropdown | This outcome fires immediately when the show instance method is called. |
| shown.bs.dropdown | This event is fired when the dropdown has been fabricated visible to the user (will wait for CSS transitions, to complete). |
| hide.bs.dropdown | This upshot is fired immediately when the hibernate instance method has been called. |
| subconscious.bs.dropdown | This outcome is fired when the dropdown has finished existence hidden from the user (will wait for CSS transitions, to complete). |
$ ( '#myDropdown' ). on ( 'testify.bs.dropdown' , part () { // exercise something… }) The ScrollSpy plugin is for automatically updating nav targets based on scroll position. Scroll the surface area beneath the navbar and spotter the agile class change. The dropdown sub items will be highlighted as well.
Requires relative positioning
No matter the implementation method, scrollspy requires the use of position: relative; on the element you're spying on. In most cases this is the <body>. When scrollspying on elements other than the <body>, be sure to accept a height set and overflow-y: scroll; practical.
Via information attributes
To hands add scrollspy behavior to your topbar navigation, add together data-spy="scroll" to the element you want to spy on (near typically this would be the <torso>). So add the data-target attribute with the ID or class of the parent element of whatever Bootstrap .nav component.
body { position : relative ; } <trunk data-spy= "scroll" data-target= "#navbar-example" > ... <div id= "navbar-example" > <ul class= "nav nav-tabs" role= "tablist" > ... </ul> </div> ... </body> Via JavaScript
Later on adding position: relative; in your CSS, call the scrollspy via JavaScript:
$ ( 'torso' ). scrollspy ({ target : '#navbar-example' }) Methods
.scrollspy('refresh')
When using scrollspy in conjunction with calculation or removing of elements from the DOM, y'all'll need to phone call the refresh method like so:
$ ( '[information-spy="whorl"]' ). each ( role () { var $spy = $ ( this ). scrollspy ( 'refresh' ) }) Options
Options tin be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in information-get-go="".
| Name | type | default | description |
|---|---|---|---|
| offset | number | ten | Pixels to kickoff from top when calculating position of coil. |
Events
| Event Type | Description |
|---|---|
| activate.bs.scrollspy | This event fires whenever a new item becomes activated by the scrollspy. |
$ ( '#myScrollspy' ). on ( 'activate.bs.scrollspy' , function () { // practice something… }) Example tabs
Add quick, dynamic tab functionality to transition through panes of local content, fifty-fifty via dropdown menus. Nested tabs are not supported.

Usage
Enable tabbable tabs via JavaScript (each tab needs to be activated individually):
$ ( '#myTabs a' ). click ( function ( e ) { e . preventDefault () $ ( this ). tab ( 'show' ) }) Y'all can actuate individual tabs in several ways:
$ ( '#myTabs a[href="#profile"]' ). tab ( 'prove' ) // Select tab by name $ ( '#myTabs a:kickoff' ). tab ( 'show' ) // Select first tab $ ( '#myTabs a:last' ). tab ( 'show' ) // Select last tab $ ( '#myTabs li:eq(2) a' ). tab ( 'show' ) // Select tertiary tab (0-indexed) Markup
You can actuate a tab or pill navigation without writing whatsoever JavaScript past simply specifying data-toggle="tab" or information-toggle="pill" on an element. Calculation the nav and nav-tabs classes to the tab ul will apply the Bootstrap tab styling, while calculation the nav and nav-pills classes will apply pill styling.
<div> <!-- Nav tabs --> <ul class= "nav nav-tabs" part= "tablist" > <li role= "presentation" class= "active" ><a href= "#home" aria-controls= "home" part= "tab" information-toggle= "tab" >Domicile</a></li> <li role= "presentation" ><a href= "#profile" aria-controls= "profile" role= "tab" data-toggle= "tab" >Profile</a></li> <li role= "presentation" ><a href= "#messages" aria-controls= "messages" function= "tab" data-toggle= "tab" >Letters</a></li> <li role= "presentation" ><a href= "#settings" aria-controls= "settings" role= "tab" data-toggle= "tab" >Settings</a></li> </ul> <!-- Tab panes --> <div class= "tab-content" > <div role= "tabpanel" class= "tab-pane active" id= "dwelling" >...</div> <div role= "tabpanel" grade= "tab-pane" id= "profile" >...</div> <div role= "tabpanel" form= "tab-pane" id= "letters" >...</div> <div part= "tabpanel" form= "tab-pane" id= "settings" >...</div> </div> </div> Fade event
To make tabs fade in, add .fade to each .tab-pane. The first tab pane must also have .in to make the initial content visible.
<div grade= "tab-content" > <div role= "tabpanel" form= "tab-pane fade in active" id= "home" >...</div> <div role= "tabpanel" grade= "tab-pane fade" id= "contour" >...</div> <div role= "tabpanel" class= "tab-pane fade" id= "messages" >...</div> <div role= "tabpanel" class= "tab-pane fade" id= "settings" >...</div> </div> Methods
$().tab
Activates a tab element and content container. Tab should take either a data-target or an href targeting a container node in the DOM. In the to a higher place examples, the tabs are the <a>due south with information-toggle="tab" attributes.
.tab('evidence')
Selects the given tab and shows its associated content. Whatever other tab that was previously selected becomes unselected and its associated content is hidden. Returns to the caller before the tab pane has actually been shown (i.e. before the shown.bs.tab event occurs).
$ ( '#someTab' ). tab ( 'show' ) Events
When showing a new tab, the events fire in the following lodge:
-
hide.bs.tab(on the current agile tab) -
testify.bs.tab(on the to-be-shown tab) -
subconscious.bs.tab(on the previous agile tab, the same one every bit for thehide.bs.tabevent) -
shown.bs.tab(on the newly-active just-shown tab, the same one as for theshow.bs.tabevent)
If no tab was already active, so the hibernate.bs.tab and subconscious.bs.tab events volition not be fired.
| Event Type | Description |
|---|---|
| show.bs.tab | This upshot fires on tab show, just before the new tab has been shown. Use event.target and outcome.relatedTarget to target the active tab and the previous active tab (if bachelor) respectively. |
| shown.bs.tab | This event fires on tab evidence subsequently a tab has been shown. Use event.target and event.relatedTarget to target the agile tab and the previous active tab (if available) respectively. |
| hide.bs.tab | This outcome fires when a new tab is to be shown (and thus the previous active tab is to be hidden). Use upshot.target and event.relatedTarget to target the electric current active tab and the new soon-to-be-active tab, respectively. |

$ ( 'a[data-toggle="tab"]' ). on ( 'shown.bs.tab' , function ( e ) { e . target // newly activated tab e . relatedTarget // previous active tab }) Inspired by the excellent jQuery.tipsy plugin written by Jason Frame; Tooltips are an updated version, which don't rely on images, use CSS3 for animations, and data-attributes for local title storage.
Tooltips with zero-length titles are never displayed.

Trigger the tooltip via JavaScript:
$ ( '#case' ). tooltip ( options ) Markup
The required markup for a tooltip is only a data aspect and title on the HTML element you lot wish to have a tooltip. The generated markup of a tooltip is rather simple, though it does require a position (by default, set to top past the plugin).
<!-- HTML to write --> <a href= "#" data-toggle= "tooltip" championship= "Some tooltip text!" >Hover over me</a> <!-- Generated markup by the plugin --> <div grade= "tooltip acme" part= "tooltip" > <div course= "tooltip-arrow" ></div> <div class= "tooltip-inner" > Some tooltip text! </div> </div> Options
Options can be passed via data attributes or JavaScript. For information attributes, append the option proper name to data-, as in information-animation="".
Note that for security reasons the sanitize, sanitizeFn and whiteList options cannot be supplied using data attributes.

Methods
$().tooltip(options)
Attaches a tooltip handler to an element collection.
.tooltip('show')
Reveals an element's tooltip. Returns to the caller earlier the tooltip has actually been shown (i.e. before the shown.bs.tooltip event occurs). This is considered a "transmission" triggering of the tooltip. Tooltips with zero-length titles are never displayed.
$ ( '#element' ). tooltip ( 'show' ) .tooltip('hide')
Hides an element's tooltip. Returns to the caller before the tooltip has really been hidden (i.east. before the hidden.bs.tooltip effect occurs). This is considered a "manual" triggering of the tooltip.
$ ( '#element' ). tooltip ( 'hibernate' ) .tooltip('toggle')
Toggles an element'south tooltip. Returns to the caller before the tooltip has actually been shown or subconscious (i.e. earlier the shown.bs.tooltip or hidden.bs.tooltip event occurs). This is considered a "manual" triggering of the tooltip.
$ ( '#element' ). tooltip ( 'toggle' ) .tooltip('destroy')
Hides and destroys an element's tooltip. Tooltips that utilize delegation (which are created using the selector option) cannot be individually destroyed on descendant trigger elements.
$ ( '#chemical element' ). tooltip ( 'destroy' ) Events
| Event Type | Description |
|---|---|
| bear witness.bs.tooltip | This event fires immediately when the show instance method is called. |
| shown.bs.tooltip | This event is fired when the tooltip has been made visible to the user (will wait for CSS transitions to complete). |
| hide.bs.tooltip | This event is fired immediately when the hide instance method has been called. |
| hidden.bs.tooltip | This effect is fired when the tooltip has finished being hidden from the user (volition wait for CSS transitions to complete). |
| inserted.bs.tooltip | This event is fired after the show.bs.tooltip issue when the tooltip template has been added to the DOM. |
$ ( '#myTooltip' ). on ( 'hidden.bs.tooltip' , role () { // exercise something… }) Add small overlays of content, like those on the iPad, to any element for housing secondary information.
Popovers whose both title and content are zero-length are never displayed.
Opt-in functionality
For performance reasons, the Tooltip and Popover data-apis are opt-in, meaning you must initialize them yourself.
One mode to initialize all popovers on a page would be to select them past their data-toggle attribute:
$ ( function () { $ ( '[data-toggle="popover"]' ). popover () }) Popovers in push button groups, input groups, and tables require special setting
When using popovers on elements within a .btn-group or an .input-grouping, or on table-related elements (<td>, <th>, <tr>, <thead>, <tbody>, <tfoot>), you lot'll take to specify the option container: 'trunk' (documented below) to avert unwanted side effects (such as the element growing wider and/or losing its rounded corners when the popover is triggered).
Popovers on disabled elements require wrapper elements
To add together a popover to a disabled or .disabled chemical element, put the element within of a <div> and utilise the popover to that <div> instead.
Multiple-line links
Sometimes you desire to add a popover to a hyperlink that wraps multiple lines. The default behavior of the popover plugin is to center it horizontally and vertically. Add together white-infinite: nowrap; to your anchors to avoid this.
Examples
Static popover
Four options are available: pinnacle, correct, bottom, and left aligned.
Popover superlative
Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.
Popover correct
Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.
Popover bottom
Sed posuere consectetur est at lobortis. Aenean european union leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.
Popover left
Sed posuere consectetur est at lobortis. Aenean eu leo quam. Pellentesque ornare sem lacinia quam venenatis vestibulum.

Utilise the focus trigger to dismiss popovers on the next click that the user makes.
Specific markup required for dismiss-on-next-click
For proper cross-browser and cross-platform behavior, yous must use the <a> tag, not the <push> tag, and you also must include the part="push button" and tabindex attributes.
<a tabindex= "0" class= "btn btn-lg btn-danger" part= "push button" data-toggle= "popover" data-trigger= "focus" championship= "Dismissible popover" data-content= "And here's some amazing content. It's very engaging. Correct?" >Dismissible popover</a> Usage

Data attributes for individual popovers
Options for private popovers can alternatively be specified through the utilise of data attributes, as explained higher up.
Methods
$().popover(options)
Initializes popovers for an chemical element drove.
.popover('bear witness')
Reveals an element's popover. Returns to the caller before the popover has actually been shown (i.e. before the shown.bs.popover event occurs). This is considered a "manual" triggering of the popover. Popovers whose both title and content are zero-length are never displayed.
$ ( '#element' ). popover ( 'testify' ) .popover('hide')
Hides an element's popover. Returns to the caller before the popover has actually been hidden (i.e. earlier the hidden.bs.popover event occurs). This is considered a "manual" triggering of the popover.
$ ( '#element' ). popover ( 'hide' ) .popover('toggle')
Toggles an chemical element's popover. Returns to the caller earlier the popover has actually been shown or hidden (i.e. before the shown.bs.popover or hidden.bs.popover event occurs). This is considered a "manual" triggering of the popover.
$ ( '#element' ). popover ( 'toggle' ) .popover('destroy')
Hides and destroys an element'due south popover. Popovers that utilise delegation (which are created using the selector option) cannot be individually destroyed on descendant trigger elements.
$ ( '#element' ). popover ( 'destroy' ) Events
| Effect Blazon | Clarification |
|---|---|
| show.bs.popover | This issue fires immediately when the testify instance method is called. |
| shown.bs.popover | This consequence is fired when the popover has been made visible to the user (will wait for CSS transitions to consummate). |
| hide.bs.popover | This outcome is fired immediately when the hide instance method has been called. |
| hidden.bs.popover | This event is fired when the popover has finished being hidden from the user (will await for CSS transitions to consummate). |
| inserted.bs.popover | This event is fired after the testify.bs.popover upshot when the popover template has been added to the DOM. |
$ ( '#myPopover' ). on ( 'hidden.bs.popover' , office () { // do something… }) Example alerts
Add dismiss functionality to all warning letters with this plugin.
When using a .close button, it must be the first kid of the .alert-dismissible and no text content may come up before information technology in the markup.
Usage
But add data-dismiss="alert" to your close push button to automatically give an alert close functionality. Closing an alert removes it from the DOM.
<button type= "button" class= "close" data-dismiss= "alert" aria-label= "Close" > <span aria-hidden= "true" > × </span> </button> To accept your alerts use animation when closing, make sure they have the .fade and .in classes already applied to them.
Methods
$().alert()
Makes an alarm listen for click events on descendant elements which have the data-dismiss="alarm" attribute. (Not necessary when using the information-api's automobile-initialization.)
$().alert('shut')
Closes an alert by removing it from the DOM. If the .fade and .in classes are present on the element, the alert will fade out before it is removed.
Events
Bootstrap'due south warning plugin exposes a few events for hooking into alert functionality.
| Effect Type | Description |
|---|---|
| close.bs.alert | This consequence fires immediately when the shut instance method is chosen. |
| airtight.bs.warning | This event is fired when the alarm has been airtight (will await for CSS transitions to consummate). |
$ ( '#myAlert' ). on ( 'airtight.bs.alert' , function () { // do something… }) Exercise more than with buttons. Control button states or create groups of buttons for more components like toolbars.
Stateful
Add information-loading-text="Loading..." to use a loading state on a push.
This characteristic is deprecated since v3.3.5 and has been removed in v4.
Employ whichever state you like!
For the sake of this demonstration, we are using data-loading-text and $().button('loading'), but that's non the just state yous can use. Come across more on this below in the $().push(string) documentation.
<button type= "push" id= "myButton" data-loading-text= "Loading..." class= "btn btn-primary" > Loading state </push button> <script> $ ( '#myButton' ). on ( 'click' , function () { var $btn = $ ( this ). button ( 'loading' ) // business logic... $btn . button ( 'reset' ) }) </script> Single toggle
Add data-toggle="button" to activate toggling on a single push.
Pre-toggled buttons need .agile and aria-pressed="true"
For pre-toggled buttons, you lot must add the .active class and the aria-pressed="true" attribute to the button yourself.
<button type= "push" class= "btn btn-main" data-toggle= "button" aria-pressed= "false" > Unmarried toggle </button> Checkbox / Radio
Add data-toggle="buttons" to a .btn-group containing checkbox or radio inputs to enable toggling in their respective styles.
Preselected options need .agile
For preselected options, you must add the .active course to the input'south label yourself.
Visual checked state only updated on click
If the checked country of a checkbox push button is updated without firing a click event on the button (east.g. via <input type="reset"> or via setting the checked property of the input), you will demand to toggle the .agile class on the input'south label yourself.
<div class= "btn-grouping" data-toggle= "buttons" > <characterization class= "btn btn-main active" > <input type= "checkbox" checked > Checkbox 1 (pre-checked) </label> <label form= "btn btn-primary" > <input blazon= "checkbox" > Checkbox ii </characterization> <label form= "btn btn-main" > <input type= "checkbox" > Checkbox iii </label> </div>
<div class= "btn-grouping" information-toggle= "buttons" > <label class= "btn btn-primary active" > <input type= "radio" name= "options" id= "option1" checked > Radio ane (preselected) </characterization> <label class= "btn btn-primary" > <input type= "radio" name= "options" id= "option2" > Radio 2 </characterization> <label class= "btn btn-chief" > <input blazon= "radio" name= "options" id= "option3" > Radio 3 </label> </div> Methods
$().button('toggle')
Toggles push button state. Gives the button the appearance that information technology has been activated.
$().push('reset')
Resets button state - swaps text to original text. This method is asynchronous and returns before the resetting has actually completed.
$().button(string)
Swaps text to any data defined text state.
<push blazon= "button" id= "myStateButton" data-complete-text= "finished!" grade= "btn btn-principal" > ... </push button> <script> $ ( '#myStateButton' ). on ( 'click' , function () { $ ( this ). button ( 'complete' ) // button text will be "finished!" }) </script> Flexible plugin that utilizes a scattering of classes for easy toggle behavior.
Plugin dependency
Collapse requires the transitions plugin to exist included in your version of Bootstrap.
Case
Click the buttons below to show and hibernate another element via class changes:
-
.plummethides content -
.collapsingis applied during transitions -
.plummet.inshows content
You can apply a link with the href attribute, or a push button with the data-target attribute. In both cases, the data-toggle="collapse" is required.
Link with href

Make expand/collapse controls accessible
Be certain to add aria-expanded to the command chemical element. This attribute explicitly defines the current state of the collapsible element to screen readers and similar assistive technologies. If the collapsible chemical element is closed past default, information technology should take a value of aria-expanded="false". If you lot've set the collapsible chemical element to exist open by default using the in class, set aria-expanded="true" on the control instead. The plugin volition automatically toggle this attribute based on whether or non the collapsible chemical element has been opened or closed.
Additionally, if your control chemical element is targeting a single collapsible element – i.e. the data-target attribute is pointing to an id selector – you may add an boosted aria-controls attribute to the control element, containing the id of the collapsible element. Modern screen readers and like assistive technologies make use of this attribute to provide users with boosted shortcuts to navigate directly to the collapsible element itself.
Usage
The collapse plugin utilizes a few classes to handle the heavy lifting:
-
.collapsehides the content -
.plummet.inshows the content -
.collapsingis added when the transition starts, and removed when information technology finishes
These classes tin be found in component-animations.less.
Via data attributes
Simply add together data-toggle="collapse" and a data-target to the element to automatically assign control of a collapsible element. The data-target attribute accepts a CSS selector to apply the collapse to. Exist sure to add together the class collapse to the collapsible element. If you'd like it to default open, add the additional course in.
To add accordion-like grouping management to a collapsible control, add the data attribute data-parent="#selector". Refer to the demo to run across this in activeness.
Via JavaScript
Enable manually with:
$ ( '.collapse' ). collapse () Options
Options can be passed via information attributes or JavaScript. For data attributes, append the pick name to data-, equally in information-parent="".
| Name | type | default | clarification |
|---|---|---|---|
| parent | selector | imitation | If a selector is provided, so all collapsible elements under the specified parent will be closed when this collapsible item is shown. (like to traditional accordion behavior - this is dependent on the console class) |
| toggle | boolean | truthful | Toggles the collapsible element on invocation |
Methods
.collapse(options)
Activates your content as a collapsible element. Accepts an optional options object.
$ ( '#myCollapsible' ). collapse ({ toggle : false }) .collapse('toggle')
Toggles a collapsible element to shown or hidden. Returns to the caller earlier the collapsible element has really been shown or hidden (i.east. before the shown.bs.plummet or hidden.bs.plummet issue occurs).
.collapse('evidence')
Shows a collapsible chemical element. Returns to the caller before the collapsible element has actually been shown (i.east. before the shown.bs.collapse event occurs).
.collapse('hide')
Hides a collapsible element. Returns to the caller before the collapsible element has actually been hidden (i.due east. before the hidden.bs.collapse event occurs).
Events
Bootstrap's plummet class exposes a few events for hooking into collapse functionality.
| Event Blazon | Description |
|---|---|
| show.bs.collapse | This outcome fires immediately when the show example method is called. |
| shown.bs.collapse | This consequence is fired when a collapse element has been made visible to the user (will wait for CSS transitions to complete). |
| hide.bs.collapse | This issue is fired immediately when the hide method has been chosen. |
| hidden.bs.collapse | This event is fired when a collapse element has been hidden from the user (will wait for CSS transitions to consummate). |

Transition animations not supported in Internet Explorer 8 & ix
Bootstrap exclusively uses CSS3 for its animations, just Internet Explorer 8 & 9 don't support the necessary CSS backdrop. Thus, at that place are no slide transition animations when using these browsers. We have intentionally decided not to include jQuery-based fallbacks for the transitions.
Initial agile chemical element required
The .active class needs to be added to one of the slides. Otherwise, the carousel will non be visible.
Glyphicon icons non necessary
The .glyphicon .glyphicon-chevron-left and .glyphicon .glyphicon-chevron-right classes are not necessarily needed for the controls. Bootstrap provides .icon-prev and .icon-next every bit plainly unicode alternatives.
Optional captions
Add together captions to your slides hands with the .carousel-caption element within any .item. Identify just nearly whatsoever optional HTML within there and it volition exist automatically aligned and formatted.
First slide label
Nulla vitae elit libero, a pharetra augue mollis interdum.
Second slide label
Lorem ipsum dolor sit amet, consectetur adipiscing elit.
Third slide label
Praesent commodo cursus magna, vel scelerisque nisl consectetur.
Previous Next
<div form= "item" > <img src= "..." alt= "..." > <div class= "carousel-explanation" > <h3>...</h3> <p>...</p> </div> </div> Usage
Multiple carousels
Carousels require the use of an id on the outermost container (the .carousel) for carousel controls to function properly. When adding multiple carousels, or when changing a carousel's id, exist sure to update the relevant controls.
Via data attributes
Utilize data attributes to easily control the position of the carousel. information-slide accepts the keywords prev or next, which alters the slide position relative to its current position. Alternatively, employ data-slide-to to pass a raw slide index to the carousel data-slide-to="two", which shifts the slide position to a particular index showtime with 0.
The information-ride="carousel" aspect is used to marking a carousel every bit animative starting at page load. It cannot be used in combination with (redundant and unnecessary) explicit JavaScript initialization of the aforementioned carousel.
Via JavaScript
Telephone call carousel manually with:
$ ( '.carousel' ). carousel () Options
Options tin can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-interval="".
| Proper noun | type | default | description |

| pause | string | zero | "hover" | If set to "hover", pauses the cycling of the carousel on mouseenter and resumes the cycling of the carousel on mouseleave. If set to nix, hovering over the carousel won't pause it. |
| wrap | boolean | true | Whether the carousel should bike continuously or have hard stops. |
| keyboard | boolean | true | Whether the carousel should react to keyboard events. |
Methods
.carousel(options)

Events

Both events have the post-obit additional backdrop:
-
management: The direction in which the carousel is sliding (either"left"or"right"). -
relatedTarget: The DOM element that is being slid into place as the active item.
All carousel events are fired at the carousel itself (i.e. at the <div grade="carousel">).
| Effect Blazon | Description |
|---|---|
| slide.bs.carousel | This event fires immediately when the slide instance method is invoked. |
| slid.bs.carousel | This event is fired when the carousel has completed its slide transition. |
$ ( '#myCarousel' ). on ( 'slide.bs.carousel' , function () { // exercise something… }) Example
The affix plugin toggles position: fixed; on and off, emulating the consequence establish with position: pasty;. The subnavigation on the right is a alive demo of the affix plugin.
Usage
Utilise the affix plugin via data attributes or manually with your own JavaScript. In both situations, yous must provide CSS for the positioning and width of your affixed content.
Annotation: Do not employ the braze plugin on an chemical element contained in a relatively positioned element, such as a pulled or pushed column, due to a Safari rendering problems.
Positioning via CSS
The affix plugin toggles between three classes, each representing a particular land: .affix, .affix-elevation, and .braze-bottom. Y'all must provide the styles, with the exception of position: fixed; on .affix, for these classes yourself (independent of this plugin) to handle the bodily positions.
Here'south how the affix plugin works:
- To start, the plugin adds
.affix-topto signal the chemical element is in its acme-almost position. At this point no CSS positioning is required. - Scrolling by the element you desire affixed should trigger the actual affixing. This is where
.affixreplaces.affix-elevationand setsposition: stock-still;(provided past Bootstrap's CSS). - If a bottom offset is defined, scrolling past it should replace
.brazewith.braze-bottom. Since offsets are optional, setting one requires you to set the appropriate CSS. In this instance, addposition: absolute;when necessary. The plugin uses the data attribute or JavaScript option to make up one's mind where to position the chemical element from there.
Follow the to a higher place steps to set your CSS for either of the usage options below.
Via data attributes
To hands add affix behavior to whatever chemical element, merely add information-spy="affix" to the element you lot want to spy on. Use offsets to define when to toggle the pinning of an element.
<div data-spy= "braze" data-starting time-meridian= "sixty" data-offset-lesser= "200" > ... </div> Via JavaScript
Call the affix plugin via JavaScript:
$ ( '#myAffix' ). affix ({ beginning : { top : 100 , bottom : role () { return ( this . lesser = $ ( '.footer' ). outerHeight ( true )) } } }) Options
Options tin can be passed via data attributes or JavaScript. For data attributes, suspend the selection name to data-, as in information-first-elevation="200".
| Name | blazon | default | clarification |
|---|---|---|---|
| offset | number | function | object | 10 | Pixels to commencement from screen when calculating position of scroll. If a single number is provided, the showtime volition be applied in both top and bottom directions. To provide a unique, lesser and acme showtime just provide an object offset: { peak: ten } or offset: { top: x, bottom: 5 }. Use a function when you need to dynamically summate an outset. |
| target | selector | node | jQuery element | the window object | Specifies the target chemical element of the braze. |
Methods
.affix(options)
Activates your content as affixed content. Accepts an optional options object.
$ ( '#myAffix' ). affix ({ offset : 15 }) .affix('checkPosition')
Recalculates the state of the braze based on the dimensions, position, and scroll position of the relevant elements. The .braze, .affix-pinnacle, and .affix-lesser classes are added to or removed from the affixed content according to the new land. This method needs to be called whenever the dimensions of the affixed content or the target element are changed, to ensure correct positioning of the affixed content.
$ ( '#myAffix' ). affix ( 'checkPosition' ) Events
Bootstrap's braze plugin exposes a few events for hooking into affix functionality.
| Effect Blazon | Description |
|---|---|
| affix.bs.affix | This event fires immediately before the element has been affixed. |
| affixed.bs.affix | This event is fired after the element has been affixed. |
| affix-summit.bs.affix | This event fires immediately before the element has been affixed-top. |
| affixed-top.bs.affix | This upshot is fired after the chemical element has been affixed-top. |
| affix-bottom.bs.braze | This outcome fires immediately earlier the chemical element has been affixed-bottom. |
| affixed-bottom.bs.braze | This event is fired subsequently the element has been affixed-bottom. |
