Return a set from ajax to JavaScript

I have an ajax call which will return a set<E>. I need to process this set from the JavaScript function from which I call this ajax. 

<script type="text/javascript">
    function mySr(id){ 
      $.ajax({
         type: 'POST',
         url: '../controller/action',
         data: 'id=' + id,
         success: function(data) {                 
             var length= data.length
             var size = data.size
             alert(data[0]+'----'+length+'--'+size+'----'+data)

         },
         error: function () {
             alert('error')
         } 
     });
    </script>

This is the way i used,
The alert will display like this

["37", "40","80","90"]----22--undefined----[

I understood the data is clearly reached in the script but i don't know how to iterate through it.
How to iterate here?
How to get the length?
How to get each elements?

You need to parse the data. Try putting data = $.parseJSON(data); after the line success: function(data) {

See http://api.jquery.com/jQuery.parseJSON/ for more details.
