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.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
