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 <

Ajax already gives you a callback, you are supposed to use it:

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