Prevents the "bubbling" effect for text selections in the DOM. For example, when you double-click a block of text on a web page and the entire block gets highlighted and selected. Yeah, this prevents that.

$.fn.disableSelection();

(function($){
	$.fn.disableSelection = function() {
		return this.each(function() {
			$(this).attr('unselectable', 'on')
				   .css({
					   '-moz-user-select':'none',
					   '-webkit-user-select':'none',
					   'user-select':'none'
				   })
				   .each(function() {
					   this.onselectstart = function() {
						   return false;
						};
				   });
		});
	};
})(jQuery);
