title: Jquery Ajax Post request issues
body: <p>In the following code when I pass static value in <code>testArr</code> for instance, <code>[2, 3]</code>; I get <code>testArr[0] =&gt; 2 and testArr[1] =&gt; 3</code> which is correct. However if I pass dynamic value to <code>testArr</code> for instance <code>test</code>; I get <code>testArr[0] =&gt; 2,3</code>. I could not figure out the problem. Please help.</p>
  
  <pre><code>            var test = '1' + ',' + '2';
              $.ajax({
                  url : url,
                  type : "post",
                  data : {
                      'testArr[]' : [test]
  
                  },
                  success : function(response) {
                      alert(response);
                  }
              });
  </code></pre>
