尽管从服务器发送了响应数据，但 JSON 请求仍直接跳转到错误语句

Question

Background :

this is a simple ajax request to fetch data from database, my query and server side code works just fine.

Problem :

When i put the GET URL in my browser it shows the correct JSON response, but firebug (Firefox extension) doesn't show any response, and the error message is logged.

alert('success'); doesn't show

$('#loadOrderDetails').click(function () {
 var id = document.getElementById("order_id").value;
 var dataString = 'order_id=' + id ;
  alert(dataString);
    $.ajax({
    type: "GET",
    url: "index.php?route=new/orders/GetOrder",
    data: dataString,
    cache: false,
    dataType: 'json',
    success: function (data) {
    alert ('success');
   // my code to show data in table..
                  },
                  error: function (req, status, err) {
                      console.log('something went wrong', status, err);
                  }
              })
          });

any suggestions?
