Handle 500 errors in JSON (jQuery)

ajax, jquery, json

Solution

Did you try `statuscode` callback like

 $.ajax({
    statusCode: {
        500: function() {
          alert("Script exhausted");
        }
      }
   });

Problem

This JSON request: ``` $.ajax({ url:jSONurl+'?orderID='+thisOrderID+'&variationID='+thisVariationID+'&quantity='+thisQuantity+'&callback=?', async: false, type: 'POST', dataType: 'json', success: function(data) { if (data.response == 'success'){ //show the tick. allow the booking to go through $('#loadingSML'+thisVariationID).hide(); $('#tick'+thisVariationID).show(); }else{ //show the cross. Do not allow the booking to be made $('#loadingSML'+thisVariationID).hide(); $('#cross'+thisVariationID).hide(); $('#unableToReserveError').slideDown(); //disable the form $('#OrderForm_OrderForm input').attr('disabled','disabled'); } }, error: function(data){ alert('error'); } }) ``` In certain circumstances will bring back a 500 error in the form of: ``` jQuery17205593111887289146_1338951277057({"message":"Availability exhausted","status":500}); ``` This however is still useful to me and I need to be able to be able to handle this correctly. For some reason though, when this 500 error is returned, my error function is not called and I just get a "NetworkError: 500 Internal Server Error" error in firebug. How can I handle this?
