console.log override function for browsers without console object - such is IE8 if debugging is not enabled.

ie8_console_alert.js

var alertFallback = true;
if (typeof console === "undefined" || typeof console.log === "undefined") {
 console = {};
 if (alertFallback) {
     console.log = function(msg) {
          alert(msg);
     };
 } else {
     console.log = function() {};
 }
}
