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

Bind an event handler to be fired when the mouse leaves an element, or trigger that handler on an element. This method is a shortcut for .on('mouseleave', handler) in the first two variations, and .trigger('mouseleave') in the third. The mouseleave JavaScript event is proprietary to Internet Explorer. Because of the event's general utility, jQuery simulates this event so that it can be used regardless of browser. This event is sent to an element when

A factory function that returns a chainable utility object with methods to register multiple callbacks into callback queues, invoke callback queues, and relay the success or failure state of any synchronous or asynchronous function. The jQuery.Deferred() factory creates a new deferred object. The jQuery.Deferred method can be passed an optional function, which is called just before the method returns and is passed the new deferred object as both the t

Selects all elements that are hidden. Elements can be considered hidden for several reasons: They have a CSS display value of none. They are form elements with type="hidden". Their width and height are explicitly set to 0. An ancestor element is hidden, so the element is not shown on the page. Elements with visibility: hidden or opacity: 0 are considered to be visible, since they still consume space in the layout. During animations that hide an elem

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

Icons jQuery UI provides a number of icons that can be used by applying class names to elements. The class names generally follow a syntax of .ui-icon-{icon type}-{icon sub description}-{direction}. For example, the following will display an icon of a thick arrow pointing north: <span class="ui-icon ui-icon-arrowthick-1-n"></span> The icons are also integrated into a number of jQuery UI's widgets, such as accordion, button, menu. The following is a full list of the icons provided:

Selects all elements that are the nth-child of their parent, counting from the last element to the first. Because jQuery's implementation of :nth- selectors is strictly derived from the CSS specification, the value of n is "1-indexed", meaning that the counting starts at 1. For other selector expressions such as :eq() or :even jQuery follows JavaScript's "0-indexed" counting. Given a single <ul> containing three <li>s, $( "li:nth-last-chil

Bind an event handler to the "click" JavaScript event, or trigger that event on an element. This method is a shortcut for .on( "click", handler ) in the first two variations, and .trigger( "click" ) in the third. The click event is sent to an element when the mouse pointer is over the element, and the mouse button is pressed and released. Any HTML element can receive this event. For example, consider the HTML: <div id="target"> Click here <

Hide the matched elements by fading them to transparent. The .fadeOut() method animates the opacity of the matched elements. Once the opacity reaches 0, the display style property is set to none, so the element no longer affects the layout of the page. Durations are given in milliseconds; higher values indicate slower animations, not faster ones. The strings 'fast' and 'slow' can be supplied to indicate durations of 200 and 600 milliseconds, respectiv

Creates a button widget Buttons Buttons are coded with standard HTML input elements, then enhanced by jQuery Mobile to make them more attractive and useable on a mobile device. Form buttons For ease of styling, the framework automatically converts any input element with a type of submit, reset, or button into a custom styled button - there is no need to add the data-role="button" attribute. However, if needed, you can directly call the button p
