Bind an event handler to the "load" JavaScript event. This method is a shortcut for .on( "load", handler ). The load event is sent to an element when it and all sub-elements have been completely loaded. This event can be sent to any element associated with a URL: images, scripts, frames, iframes, and the window object. For example, consider a page with a simple image: <img src="book.png" alt="Book" id="book"> The event handler can be bound to th

Attach an event handler for all elements which match the current selector, now and in the future. As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers. Users of older versions of jQuery should use .delegate() in preference to .live(). This method provides a means to attach delegated event handlers to the document element of a page, which simplifies the use of event handlers when content is dynamically added to a page.

A collection of properties that represent the presence of different browser features or bugs. Intended for jQuery's internal use; specific properties may be removed when they are no longer needed internally to improve page startup performance. For your own project's feature-detection needs, we strongly recommend the use of an external library such as Modernizr instead of dependency on properties in jQuery.support. jQuery.sup

Creates a new copy of jQuery whose properties and methods can be modified without affecting the original jQuery object. This method is deprecated as of jQuery 1.7 and will be moved to a plugin in jQuery 1.8. There are two specific use cases for which jQuery.sub() was created. The first was for providing a painless way of overriding jQuery methods without completely destroying the original methods and another was for helping to do encapsulation and b

Provides a way to execute callback functions based on one or more objects, usually Deferred objects that represent asynchronous events. If a single Deferred is passed to jQuery.when(), its Promise object (a subset of the Deferred methods) is returned by the method. Additional methods of the Promise object can be called to attach callbacks, such as deferred.then. When the Deferred is resolved or rejected, usually by the code that created the Deferred o

Selects the last matched element. Note that :last selects a single element by filtering the current jQuery collection and matching the last element within it. Because :last is a jQuery extension and not part of the CSS specification, queries using :last cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :last to select elements, first select the elements usin

Show the queue of functions to be executed on the matched element. Note: This is a low-level method, you should probably use .queue() instead. jQuery.queue( element [, queueName ] ) version added: 1.3 element Element A DOM element to inspect for an att

Sorts an array of DOM elements, in place, with the duplicates removed. Note that this only works on arrays of DOM elements, not strings or numbers. The $.unique() function searches through an array of objects, sorting the array, and removing any duplicate nodes. A node is considered a duplicate if it is the exact same node as one already in the array; two different nodes with identical attributes are not considered to be duplicates. This function only

Remove a previously-stored piece of data. Note: This is a low-level method, you should probably use .removeData() instead. The jQuery.removeData() method allows us to remove values that were previously set using jQuery.data(). When called with the name of a key, jQuery.removeData() deletes that particular value; when called with no arguments, all values are removed. jQuery.removeData( element [, name ] )

Remove the whitespace from the beginning and end of a string. The $.trim() function removes all newlines, spaces (including non-breaking spaces), and tabs from the beginning and end of the supplied string. If these whitespace characters occur in the middle of the string, they are preserved. jQuery.trim( str ) version added: 1.0
