      Default:

    Selected elements are in the order of their appearance in the document. Forms and their child elements should not use input names or ids that conflict with properties of a form, such as submit, length, or method. Name conflicts can cause confusing failures. For a complete list of rules and to check your markup for these problems, see DOMLint. Because is a jQuery extension and not part of the CSS specification, queries using cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using to select elements, first select the elements using a pure CSS selector, then use .filter(""). Because is a jQuery extension and not part of the CSS specification, queries using cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. For better performance in modern browsers, use instead. All jQuery effects, including , can be turned off globally by setting jQuery.fx.off = true, which effectively sets the duration to 0. For more information, see jQuery.fx.off. Note that this method currently does not provide cross-platform support for setting data on XML documents, as Internet Explorer does not allow data to be attached via expando properties. In Internet Explorer prior to version 9, using .prop() to set a DOM element property to anything other than a simple primitive value (number, string, or boolean) can cause memory leaks if the property is not removed (using .removeProp()) before the DOM element is removed from the document. To safely set values on DOM objects without memory leaks, use .data(). Since the .live() method handles events once they have propagated to the top of the document, it is not possible to stop propagation of live events. Similarly, events handled by .delegate() will propagate to the elements to which they are delegated; event handlers bound on any elements below it in the DOM tree will already have been executed by the time the delegated event handler is called. These handlers, therefore, may prevent the delegated handler from triggering by calling event.stopPropagation() or returning false. Due to browser security restrictions, most "Ajax" requests are subject to the same origin policy; the request can not successfully retrieve data from a different domain, subdomain, or protocol. Script and JSONP requests are not subject to the same origin policy restrictions. If a request with returns an error code, it will fail silently unless the script has also called the global .ajaxError() method. Alternatively, as of jQuery 1.5, the .error() method of the jqXHR object returned by is also available for error handling. ""
