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 could do this:

$(function() {
    PerformCall();        
});

function PerformCall() {
   $.getJSON("/controller/method/", null, function(data) {
       for(var i = 0; i < data.length; i++) {
        // Do stuff with data
       }
   });
}
