Execute the next function on the queue for the matched element. Note: This is a low-level method, you should probably use .dequeue() instead. When jQuery.dequeue() is called, the next function on the queue is removed from the queue, and then executed. This function should in turn (directly or indirectly) cause jQuery.dequeue() to be called, so that the sequence can continue. jQuery.dequeue( element [, queueName ]

A multi-purpose callbacks list object that provides a powerful way to manage callback lists. The $.Callbacks() function is internally used to provide the base functionality behind the jQuery $.ajax() and $.Deferred() components. It can be used as a similar base to define functionality for new components. $.Callbacks() supports a number of methods including callbacks.add(),callbacks.remove(), callbacks.fire() and callbacks.disable(). Getting started Th

An object containing all CSS properties that may be used without a unit. The .css() method uses this object to see if it may append px to unitless values. You can think about jQuery.cssNumber as a list of all CSS properties you might use without a unit. It's used by .css() to determine if it needs to add px to unitless values. The keys of the jQuery.cssNumber object are camel-cased and the values are all set to true. If you want to prevent the .css()

Perform an asynchronous HTTP (Ajax) request. The $.ajax() function underlies all Ajax requests sent by jQuery. It is often unnecessary to directly call this function, as several higher-level alternatives like $.get() and .load() are available and are easier to use. If less common options are required, though, $.ajax() can be used more flexibly. At its simplest, the $.ajax() function can be called with no arguments: $.ajax(); Note: Default settings can

Creates an object that handles the actual transmission of Ajax data. A transport is an object that provides two methods, send and abort, that are used internally by $.ajax() to issue requests. A transport is the most advanced way to enhance $.ajax() and should be used only as a last resort when prefilters and converters are insufficient. Since each request requires its own transport object instance, transports cannot be registered directly. Therefore,

Handle custom Ajax options or modify existing options before each request is sent and before they are processed by $.ajax(). A typical prefilter registration using $.ajaxPrefilter() looks like this: $.ajaxPrefilter(function( options, originalOptions, jqXHR ) { // Modify options, control originalOptions, store jqXHR, etc }); where: options are the request options originalOptions are the options as provided to the $.ajax() method, unmodified and, th

Set default values for future Ajax requests. Its use is not recommended. For details on the settings available for $.ajaxSetup(), see $.ajax(). All subsequent Ajax calls using any function will use the new settings, unless overridden by the individual calls, until the next invocation of $.ajaxSetup(). Note: The settings specified here will affect all calls to $.ajax or Ajax-based derivatives such as $.get(). This can cause undesirable behavior since

Insert every element in the set of matched elements before the target. The .before() and .insertBefore() methods perform the same task. The major difference is in the syntax-specifically, in the placement of the content and target. With .before(), the selector expression preceding the method is the container before which the content is inserted. With .insertBefore(), on the other hand, the content precedes the method, either as a selector expression o

A string containing the jQuery version number. The .jquery property is assigned to the jQuery prototype, commonly referred to by its alias $.fn. It is a string containing the version number of jQuery, such as "1.5.0" or "1.4.4". jquery version added: 1.0 Examples: Determine if an object is a

Selects all elements of type image. :image is equivalent to [type="image"] Because :image is a jQuery extension and not part of the CSS specification, queries using :image cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. For better performance in modern browsers, use [type="image"] instead. jQuery( ":image" ) version added: 1.0
