Can I extend the console object (for rerouting the logging) in javascript?

Question

Is it possible to extend the console object?

I tried something like:

Console.prototype.log = function(msg){     Console.prototype.log.call(msg);     alert(msg); } 

But this didn't work. I want to add additional logging to the console object via a framework like log4javascript and still use the standard console object (in cases where log4javascript is not available) in my code.

Thanks in advance!

Try following:

(function() {     var exLog = console.log;     console.log = function(msg) {         exLog.apply(this, arguments);         alert(msg);     } })()

You Can Also add log Time in This Way :

added Momentjs or use New Date() instead of moment.

var oldConsole = console.log; console.log = function(){     var timestamp = "[" + moment().format("YYYY-MM-DD HH:mm:ss:SSS") + "] ";     Array.prototype.unshift.call(arguments, timestamp);     oldConsole.apply(this, arguments); };
