In this way, the console object can be use to add any number of new commands you may need. var trap = function () { // create an Array from the arguments Object var args = Array.prototype.slice.call(arguments); // console.raw captures the raw args, without converting toString console.raw.push(args); var message = args.join(' '); console.messages.push(message); fallback(message); }; // redefine console if (typeof console === 'undefined') { console = { messages: [], raw: [], dump: function() { return console.messages.join('\n'); }, log: trap, debug: trap, info: trap, warn: trap, error: trap, assert: trap, clear: function() { console.messages.length = 0; console.raw.length = 0 ; }, dir: trap, dirxml: trap, trace: trap, group: trap, groupCollapsed: trap, groupEnd: trap, time: trap, timeEnd: trap, timeStamp: trap, profile: trap, profileEnd: trap, count: trap, exception: trap, table: trap }; } })(null); // to define a fallback function, replace null with the name of the function (ex: alert) Some extra info The line var args = Array.prototype.slice.call(arguments); creates an Array from the arguments Object.
