This advanced feature would typically be used by dynamic script loaders that want to load additional JavaScript such as jQuery plugins before allowing the ready event to occur, even though the DOM may be ready. This method must be called early in the document, such as in the <head> immediately after the jQuery script tag. Calling this method after the ready event has already fired will have no effect. To delay the ready event, first call $.holdReady(true). When the ready event should be released to execute, call $.holdReady(false). Note that multiple holds can be put on the ready event, one for each $.holdReady(true) call. The ready event will not actually fire until all holds have been released with a corresponding $.holdReady(false) and the normal document ready conditions are met. (See ready for more information.) Example 1: Delay the ready event until a custom plugin has loaded. Javascript $.holdReady(true); $.getScript("myplugin.js", function() { $.holdReady(false); }); jQuery.when Provides a way to execute callback functions based on one or more objects, usually Deferred objects that represent asynchronous events. jQuery.when(deferreds):Promise Added in version 1.5 deferreds:Deferred One or more Deferred objects, or plain JavaScript objects. If a single Deferred is passed to jQuery.when, its Promise object (a subset of the Deferred methods) is returned by the method. Additional methods of the Promise object can be called to attach callbacks, such as deferred.then. When the Deferred is resolved or rejected, usually by the code that created the Deferred originally, the appropriate callbacks will be called. For example, the jqXHR object returned by jQuery.ajax is a Deferred and can be used this way: $.when( $.ajax("test.aspx") ).then(function(ajaxArgs){ alert(ajaxArgs[1]); /* ajaxArgs is [ "success", statusText, jqXHR ] */ }); If a single argument is passed to jQuery.when and it is not a Deferred, it will be treated as a resolved Deferred and any doneCallbacks attached will be executed immediately. The doneCallbacks are passed the original argument. In this case any failCallbacks you might set are never called since the Deferred is never rejected. For example: $.when( { testing: 123 } ).done( function(x){ alert(x.testing); } /* alerts "123" */ ); In the case where multiple Deferred objects are passed to jQuery.when, the method returns the Promise from a new "master" Deferred object that tracks the aggregate state of all the Deferreds it has been passed. The method will resolve its master Deferred as soon as all the Deferreds resolve, or reject the master Deferred as soon as one of the Deferreds is rejected. If the master Deferred is resolved, it is passed the resolved values of all the Deferreds that were passed to jQuery.when. For example, when the Deferreds are jQuery.ajax() requests, the arguments will be the jqXHR objects for the requests, in the order they were given in the argument list. In the multiple-Deferreds case where one of the Deferreds is rejected, jQuery.when immediately fires the failCallbacks for its master Deferred. Note that some of the Deferreds may still be unresolved at that point. If you need to perform additional processing for this case, such as canceling any unfinished ajax requests, you can keep references to the underlying jqXHR objects in a closure and inspect/cancel them in the failCallback. Example 1: Execute a function after two ajax requests are successful. (See the jQuery.ajax() documentation for a complete description of success and error cases for an ajax request). Javascript $.when($.ajax("/page1.php"),
