jquery - How to display error message only in OnFailure of Ajax.BeginForm in MVC3? -

i have simple ajax form in mvc3 app, sends email message:

@using (ajax.beginform("sendmessage", new ajaxoptions {      loadingelementid = "wait",      onsuccess = "loadmessages",      onfailure = "showerror" })) {     <input type="text" name="message" placeholder="message" />     <input type="submit" name="submit" value="send" /> } 

if action fails send message, throws exception. exception handled , displayed in showerror(error){} javascript function:

function showerror(error) {      $("#error").text(error.responsetext); }; 

the problem is: error.responsetext html dump of entire error page.

i need display exception error message (whatever in ex.message in mvc3).

the implementation of "public actionresult sendmessage(string message) { }" irrelevant.

i need know how display exception's message in showerror(error) javascript handler.

thanks bunch.

    [httppost]     public actionresult sendmessage(string message)     {         mailmessage mail = new mailmessage();         smtpclient smtpserver = new smtpclient("smtp.gmail.com");         mail.from = new mailaddress("sender@gmail.com");         mail.subject = "some message";         mail.body = message;         mail.to.add("recepient@gmail.com");         smtpserver.send(mail);         return null;     } 

you cannot handle each , every exception in onfailure method. because onfailure called if response status not in 200 range. can handle scenario this:

    [httppost]     public actionresult sendmessage(string message)     {         mailmessage mail = new mailmessage();         actionresult response = null;         smtpclient smtpserver = new smtpclient("smtp.gmail.com");         mail.from = new mailaddress("sender@gmail.com");         mail.subject = "some message";         mail.body = message;         mail.to.add("recepient@gmail.com");         try         {             smtpserver.send(mail);             response = content("success");         }         catch (exception ex)         {             response = content(ex.message);         }         return response;      } 

here in code if mail send have returned response "success" else have returned actual error , in javascript have handled response this:

    function loadmessages(error) {     if (error == 'success') {         alert("mail sent successfully");     }     else {         $("#error").text(error);     } 

hope you.
