iterate php array after ajax call

Question

i got an ajax function that calls a php who returns an array:

<?php
$testing = array("one","two","three", "four");   
echo json_encode($testing);        
?>

i call it with this ajax call;

$.ajax({
url:"ajax_response.php",
type:"POST",   
success:function(msg)
{
  var array = msg;    
  var test = array[2];      
  alert(test);
}
});

the problem is that i want to get array[1] as "one" and im geting 1 character on every array position ex: array[0] = "o", array[1] = "n", array[2] = "e". Its like the json encode or semething is spliting my array variables into characters.

Any help ??

Thanks in advance

You have to parse your answer. Easiest way would be to put a dataType to your AJAX call:

$.ajax({
    url: "ajax_response.php",
    dataType: 'json', // add the dataType
    type: "POST",   
    success: function(msg) {
        var array = msg;    
        var test = array[2];      
        alert(test);
    }
});

Or you can parse it "by hand". This is sometimes necessary:

success: function(msg) {
    var array = JSON.parse(msg); // or parse it manually
    var test = array[2];      
    alert(test);
}

your response is in string format try this at your success function

success:function(msg)
{
  var array ;
 eval('array ='+msg );  
  var test = array[2];      
  alert(test);
}

Well, EVER might be extreme, but here it is NOT the right tool. Not at all. – Bruno Schäpper Aug 03 '12 at 09:03
@VainFellowman yes , I also donot fever it but I have had some problem with JSON as browser compatibility in early days so have just pasted that code I have used – Rupesh Patel Aug 03 '12 at 09:08
You are right, in older days. But there are other approaches, like JSON parse and stringify libraries. – Bruno Schäpper Aug 03 '12 at 09:16
@VainFellowman So let it be here, I am not gonna delete my answer, if nothing else work, It will work :) – Rupesh Patel Aug 03 '12 at 09:19
No problem. I just wanted to point out the better solution, and the risk of using eval(). – Bruno Schäpper Aug 03 '12 at 09:24
