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 href="http://en.wikipedia.org/wiki/Apache_Struts" rel="noreferrer">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?
