Is there some way I can show custom exception messages as an alert in my jQuery AJAX error message?
For example, if I want to throw an exception on the server side via Struts by throw new ApplicationException("User name already exists");
, I want to catch this message (‘user name already exists’) in the jQuery AJAX error message.
jQuery("#save").click(function () { if (jQuery('#form').jVal()) { jQuery.ajax({ type: "POST", url: "saveuser.do", dataType: "html", data: "userId=" + encodeURIComponent(trim(document.forms[0].userId.value)), success: function (response) { jQuery("#usergrid").trigger("reloadGrid"); clear(); alert("Details saved successfully!!!"); }, error: function (xhr, ajaxOptions, thrownError) { alert(xhr.status); alert(thrownError); } }); } });
On the second alert, where I alert the thrown error, I am getting undefined
and the status code is 500.
I am not sure where I am going wrong. What can I do to fix this problem?
