States if the current page, in the user's browser, is being rendered using the W3C CSS Box Model. This property was removed in jQuery 1.8. Please try to use feature detection instead. jQuery.boxModel version added: 1.0

Check to see if a DOM element is a descendant of another DOM element. The $.contains() method returns true if the DOM element provided by the second argument is a descendant of the DOM element provided by the first argument, whether it is a direct child or nested more deeply. Otherwise, it returns false. Only element nodes are supported; if the second argument is a text or comment node, $.contains() will return false. Note: The first argument must be

Contains flags for the useragent, read from navigator.userAgent. This property was removed in jQuery 1.9 and is available only through the jQuery.migrate plugin. Please try to use feature detection instead. The $.browser property provides information about the web browser that is accessing the page, as reported by the browser itself. It contains flags for each of the four most prevalent browser classes (Internet Explorer, Mozilla, Webkit, and Opera) a

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,

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

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

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

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
