Question

For example

function getResult(field) {
    $.ajaxSetup ({cache: false, async: false});
    $.get("api.php?field="+field, function(i) {
        result = i;
    });
    return result;
};

The problem with this is that result becomes global. If I do var result = i; then the parent function (getResult) cannot see the variable result.

Is there a clever way to do this?

The code that I have posted works correctly. I have set my AJAX calls to be done synchronously.

Answer 1

function doIt(arr) {
  var result = [];
  $.each(arr, function (y_u_key_jQuery_y_u_no_fix_api, value) {
    result.push(value);
  });
  return result;
}

Generally what you want to do is create a local variable in the outer function that the inner function manipulates through closure scope
