Console Normalizer

IE, oh IE, how we fight... this utility fixes issues with IE's console object so you can use it just like a real console.

Usage

    <script src="normalizeconsole.min.js"></script>
    <script>
        console.group('Play around');
        console.time('timer');

        console.log('hello'); // does not blow up if IE console is closed

        console.log.apply(console, ['one', 'two', 'three']); // does not cause an Invocation error

        typeof(console.log); // function (some things you shouldn't have to say...)

        console.info();
        console.warn();
        console.error();

        console.timeEnd('timer');
        console.groupEnd();
    </script>

What it fixes

IE 8 & 9's console objects are a bit... well, it's IE, our favorite stepchild. To be fair, Chrome has a few similar issues which are fixed by this utility as well. Here's a quick summary, with details below:

window.console available in IE, even if it is closed
console.log/info/warn/error.apply work in IE and Chrome
console.time and console.timeEnd supported
console.group and console.groupEnd supported
Function.prototype.bind added if it doesn't exist (for IE 8)

console is null or not an object

The window.console object is only availble in IE 8/9 when it is opened; this is also true in Chrome.

console.group and console.groupEnd

Implements compatible functions for group and groupEnd

console.time and console.timeEnd

Implements compatible functions for time and timeEnd

Function.prototype.apply

Calling apply on any of the logging methods (i.e. console.log.apply(console, arguments)) breaks with "Object doesn't support this property or method" in IE8 and a Method Invocation Error in IE 9. This is because it is a "host object" and does not extend Object.

Function.prototype.bind in IE 8

As a side effect, this utility also implements a compatible version of Function.prototype.bind for IE 8.

Compatibility

Compatible with everything after IE 5.5
