Check if a path is absolute or relative

Common method

If you only need to test for http:// or https:// then the most efficient way is:

var path = 'http://blah.com/some/other/stuff';
if (path.indexOf('http://') === 0 || path.indexOf('https://') === 0) {
   // absolute
} else {

Placeholder workaround for IE8 and lower browsers

This snippet is best used in a conditional comment block.

<!--[if lt IE 8]>
  <script src="YOUR_IE_FILE.js"></script>
<![endif]-->

/**
 * IE8 JS does not support indexOf()
 * here is my mock prototype for it.
 */
if (!Array.prototype.indexOf)
{
  Array.prototype.indexOf = function(elt /*, from*/)
  {
    var len = this.length >>> 0;
    var from = Number(arguments[1]) || 0;

#Bored of using this?

var foo = ['a', 'b', 'c'];
if( foo.indexOf('b') >= 0 ) {
    console.log('Exists!')
}

##Use bitwise instead!

};
