Redirect Javascript Syntax Errors And Console.log To Somewhere Else

I'm trying to send whatever would normally appear in the javascript console to my own custom functions. I've tried the following window.console.error = window.console.debug = wind

Solution 1:

window.onerror = function(message, source, lineno, colno, error) {
   alert(message);
}
