jQuery Select Text Range

Here's a jQuery function I wrote which you can use to select a range of text in an input field.

$.fn.selectRange = function(start, end) {
	return this.each(function() {
		if(this.setSelectionRange) {
			this.focus();
			this.setSelectionRange(start, end);
		} else if(this.createTextRange) {
			var range = this.createTextRange();
			range.collapse(true);
			range.moveEnd('character', end);
			range.moveStart('character', start);
			range.select();
		}
	});
};
