Learn all about the jQuery function jQuery.get().
This is a shorthand Ajax function, which is equivalent to:
As of jQuery 1.5, the
success callback function is also passed a "jqXHR" object (in jQuery 1.4, it was passed the
XMLHttpRequest object). However, since JSONP and cross-domain GET requests do not use XHR, in those cases the
textStatus parameters passed to the success callback are undefined.
Most implementations will specify a success handler:
This example fetches the requested HTML snippet and inserts it on the page.
The jqXHR Object
As of jQuery 1.5, all of jQuery’s Ajax methods return a superset of the
XMLHTTPRequest object. This jQuery XHR object, or "jqXHR," returned by
$.get() implements the Promise interface, giving it all the properties, methods, and behavior of a Promise (see Deferred object for more information). The
jqXHR.done() (for success),
jqXHR.fail() (for error), and
jqXHR.always() (for completion, whether success or error) methods take a function argument that is called when the request terminates. For information about the arguments this function receives, see the jqXHR Object section of the
The Promise interface also allows jQuery’s Ajax methods, including
$.get(), to chain multiple
.always() callbacks on a single request, and even to assign these callbacks after the request may have completed. If the request is already complete, the callback is fired immediately.
jqXHR.complete() callback methods introduced in jQuery 1.5 are deprecated as of jQuery 1.8. To prepare your code for their eventual removal, use
