原标题:uploadify onError not called

我们如何通过习俗错误信息来提升负荷?

如果在控制人员的行动上,有一个例外(以尝试/捕获物为选择)——我们如何将其上载文字? 永远不会援引过错误事件?

    [HttpPost]
    public ActionResult Upload(HttpPostedFileBase fileData, FormCollection forms)
    {
      try
      {                
        if (fileData.ContentLength > 0)
        {
          var statusCode = Helper.UploadList();
          if (statusCode.Equals(System.Net.HttpStatusCode.Created))
          return Json(new { success = true });                      
        }                  
      }
      return Json(new { success = false });        
    }
    catch (Exception ex)
    {  
    return Json(new { success = false });       
    }   
}

     onComplete : function (event, queueID, fileObj, response, data) {
                    if (response ==  {"success":true} ) {
                        alert("File uploaded successfully.");
                    }
                    else if (response ==  {"success":false} ) {
                        alert( File failed to upload. Please try again! );                   
                    }
                    else {
                        $("#file_uploadDomain").uploadifyCancel(queueID);
                    }
                    return false;
                },

                 onError : function(event, ID, fileObj, errorObj) {
                    alert(errorObj.type +   Error:   + errorObj.info);
                },
