Ajax Call Error Message
522 down vote favorite 189 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()) { javascript ajax error message 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? jquery ajax struts custom-exceptions share|improve this question edited Sep 9 '15 at 5:43 Kasun Randika 2,14911635 asked Dec 18 '08 at 12:06 add a comment| 16 Answers 16 active oldest votes up vote 258 down vote Make sure you're setting Response.StatusCode to something other than 200.
