Logging to the console not working in IE11

Derrick Shriver

I'm finding that in IE11, console.log() is not working. The following code is being executed to create a dummy console object. The question is why is **console** undefined in the first place. Cobalt.Loader.js

// Stub out the console if not present (e.g. IE when not debugging, Microsoft Office plugins, etc.)
if (typeof console === "undefined") {
	// Stub in dummy functions in place of all possible `console` methods
	(function() {
		var dummyFn = function() { };
		var consoleMethods = ["log", "debug", "info", "warn", "error", "assert", "clear", "dir", "dirxml", "trace", "group", "groupCollapsed", "groupEnd", "time", "timeEnd", "timeStamp", "profile", "profileEnd", "count", "exception", "table"];
		for (var c = 0, len = consoleMethods.length; c < len; c++) {
			console[consoleMethods[c]] = dummyFn;
		}
	})();

Debugging tools are open and yet console is undefined while debugging. It does become defined (per the console itself) after the page load completes, making me believe that something in Cobalt is affecting it. In IE10 mode, it works as expected.

Thanks for clarifying the potential relationship to Cobalt. Otherwise, this seems like an industry question.

We should include the answer from a link here (as per stackoverflow posting recommendations) as well as the link itself.
