Global AJAX Request Error Display for Asp.net MVC 2

So you thought you might like to,
Go to the show.
To feel the warm thrill of confusion,
That space cadet glow.
Tell me is something eluding you, sunshine?
Is this not what you expected to see?

 

Ever get that kind of feeling when trying to debug server side request errors using AJAX (MS AJAX or jQuery) in MVC. I mean, on a normal posts that fails you get the nice yellow error screen that says “Hey you …” and “Bring on the (Stack Trace)!” and makes your wonder “Is there anybody out there?”. We’ll no more. Here’s a basic script you can just hook up while building/debugging your app that if you get a server side error making an AJAX request you’ll get the same effect as a full post back.

 

Code Snippet
/// <reference path="../Common/jquery-1.4.1-vsdoc.js" />
/// <reference path="../Common/MicrosoftAjax.js" />

$(document).ready(function () {

    //replace the screen with the response error

    //jQuery —————————————————–
    $(document).ajaxError(function (event, request, settings) {

        $(document.body).html(request.responseText);

    });

    //MS AJAX —————————————————-
    function OnWebRequestComplete(executor, eventArgs) {

        if (executor.get_statusCode() === 500) {

            $(document.body).html(executor.get_responseData());
        }
    }

    Sys.Net.WebRequestManager.add_completedRequest(OnWebRequestComplete);

});
