jQuery loop over JSON result from AJAX Success?

Question

On the jQuery AJAX success callback I want to loop over the results of the object. This is an example of how the response looks in Firebug.

[
 {"TEST1":45,"TEST2":23,"TEST3":"DATA1"},
 {"TEST1":46,"TEST2":24,"TEST3":"DATA2"},
 {"TEST1":47,"TEST2":25,"TEST3":"DATA3"}
]

How can I loop over the results so that I would have access to each of the elements? I have tried something like below but this does not seem to be working.

jQuery.each(data, function(index, itemData) {
  // itemData.TEST1
  // itemData.TEST2
  // itemData.TEST3
});

Answer 1

you can remove the outer loop and replace this with data.data:

$.each(data.data, function(k, v) {
    /// do stuff
});

You were close:

$.each(data, function() {
  $.each(this, function(k, v) {
    /// do stuff
  });
});

You have an array of objects/maps so the outer loop iterates over those. The inner loop iterates over the properties on each object element.
