jQuery: wait for function to complete to continue processing?

Question

Hey all. I have, what appears to be, a trivial problem. I have the following JavaScript:

$(function() {
    var r = GetResults();

    for(var i = 0; i <

You can have a callback with parameters that should work nicely...

$(function() {
    GetResults(function(data) {
      for(var i = 0; i < data.length; i++) {
        // Do stuff with data
      }
    });

});

function GetResults(func) {
   $.getJSON("/controller/method/", null, func);
}
