Javascript: using callback functions

Hi there,

I have a function like this:

function GetResourceFunction(path, id, callback);

Open in new window

I am using it like this: So, the result is only available in the callback function.
 var GetResourceFunction(path, id, function(response){ "result is available here..."});

Open in new window

I wrote the following function to return the resources from the result.
getResources = function(path, id){
    var resources;
    GetResourceFunction(path, id, function(response){
            resources = response.result; // this callback won't be called immediately
    return resources;

Open in new window

I want to use that results in the following function.  However, as the callback is not called immediately, how can I get the results in anotherFunction?

 var anotherFunction = function() {
     //need to use the resources here....

Open in new window

You have to wait for the callback to be called.  After all, the data you want does not exist until the callback has finished, correct?

If this is an AJAX workflow, try switching the call to be synchronous.  That will "freeze" the application state until the call returns, which allows the callback to act.  Otherwise, you'll need to use something like jQuery's promise or deferred API.
