Logging Clientside JavaScript Errors on Server

How can I log client side javascript errors to the server? I’m using jQuery and MVC.

Answer 1

Since they’re client-side errors, you’ll have to send them to the server using XMLHttpRequest. You could use try...catch statements or window.onerror:

window.onerror = function (msg, url, line)
{
    var message = "Error in "+url+" on line "+line+": "+msg;
    $.post("logerror.aspx", { "msg" : message }); 
}

Be aware that line and url can be very inaccurate in IE versions prior to 8.
