getJSON Synchronous

Since $.getJSON() uses ajax configurations, just set the global ajax configs:

// Set the global configs to synchronous $.ajaxSetup({    async: false});// Your $.getJSON() request is now synchronous...// Set the global configs back to asynchronous $.ajaxSetup({    async: true});

Asynchronusly does mean the Request is running in the background, and calls your function back when it got a response. This method is best if you want to have a result but allow to use your app within the request. If you want to have a direct response, take a look at a synchron request. this request will pause script execution until it got a response, and the user can not do anything until the response was recieved. You can toggle it via:

async: false,

So for example:

$.ajax({    url: "myurl",    async: false,    ...})

$.getJSON(), doesn't accept a configuration, as it says in the docs it's a shorthand version of:

$.ajax({  dataType: "json",  url: url,  data: data,  success: success});

So just rewrite your request in terms of that and async:false will work just as you expect.
