AJAX Success event not firing

Question

Tuesday, August 5, 2014 2:58 PM

I have a webforms project and an mvc controller project.  I use the mvc controller project as a service to provide data from the db in JSON format.  The mvc controller is working fine and sends out the JSON result (verified in fiddler) but for some reason, why is my success event not firing?  The MVC project is deployed as an application in IIS and I have use the URL as my source for the ajax.

$('#ctl00_ctl00_mainbody_topnavigateright_UserStatus_lblUserTagCommentsCount').hover(function () {
$.ajax({
type: "GET",
contentType: 'application/json; charset=utf-8',
url: '<%= Global.WebServiceUrl %>' + '/services/getUserTagsByUserId?userId=113',
dataType: "json",
success: function (data) {
alert('test');
//alert(exists);
} //End Success Function
}); //End Ajax Call

});

Hello,

Based on your description, I see your ajax request return data ok but it not call the success function.

For this issue, I think the response not contains a correct json data format however your ajax function expects

a json format data.

dataType: "json",

You can remove above line for a test, and see if your success method called.

Besides, I suggest you add a error callback function to your ajax function and fine what the error is indeed.

 $.ajax({
      type: "GET",
      url: "url",
      data: cartObject,
      contentType: "application/josn",
      dataType: "json",
      success: function () {
        OnSuccess(cartObject.productID)
      },
      error: function () {
        OnError(cartObject.productID)
      },
      complete: function () {
        // Handle the complete event
        alert("ajax completed " + cartObject.productID);
      }
    });  // end Ajax
