[jQuery] assigning data from $.getJSON() to a global variable?

[funkadelic]

Hi,

Is there a way to take the JSON from a $.getJSON() call and assign it
to a var in the global scope?

i tried the following but it didn't work:

var globalX;

function foo() {
  $.getJSON("jsondata.js",function(data){
    globalX = data;
  });
}

thanks
