That said, in some situations it may be desirable to turn this functionality off. Therefore, we also provide the ability to disable the data attribute API by unbinding all events on the body namespaced with `'data-api'`. This looks like this:$('body').off('.data-api')Alternatively, to target a specific plugin, just include the plugin's name as a namespace along with the data-api namespace like this:
$('body').off('.alert.data-api')We also believe you should be able to use all Bootstrap plugins purely through the JavaScript API. All public APIs are single, chainable methods, and return the collection acted upon.
$(".btn.danger").button("toggle").addClass("fat")All methods should accept an optional options object, a string which targets a particular method, or nothing (which initiates a plugin with default behavior):
$("#myModal").modal() // initialized with defaults
$("#myModal").modal({ keyboard: false }) // initialized with no keyboard
$("#myModal").modal('show') // initializes and invokes show immediatelyEach plugin also exposes its raw constructor on a `Constructor` property: $.fn.popover.Constructor. If you'd like to get a particular plugin instance, retrieve it directly from an element: $('[rel=popover]').data('popover').

Call the scrollspy via JavaScript:
$('#navbar').scrollspy()<a href="#home">home</a> must correspond to something in the dom like <div id="home"></div>.
When using scrollspy in conjunction with adding or removing of elements from the DOM, you'll need to call the refresh method like so:
$('[data-spy="scroll"]').each(function () {
var $spy = $(this).scrollspy('refresh')
});
Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in data-offset="".

$('#myTab a').click(function (e) {

$('#myTab a[href="#profile"]').tab('show'); // Select tab by name
$('#myTab a:first').tab('show'); // Select first tab
$('#myTab a:last').tab('show'); // Select last tab
$('#myTab li:eq(2) a').tab('show'); // Select third tab (0-indexed)
You can activate a tab or pill navigation without writing any JavaScript by simply specifying data-toggle="tab" or data-toggle="pill" on an element. Adding the nav and nav-tabs classes to the tab ul will apply the Bootstrap tab styling.
<ul class="nav nav-tabs"> <li><a href="#home" data-toggle="tab">Home</a></li> <li><a href="#profile" data-toggle="tab">Profile</a></li> <li><a href="#messages" data-toggle="tab">Messages</a></li> <li><a href="#settings" data-toggle="tab">Settings</a></li> </ul>

<ul class="nav nav-tabs" id="myTab">
