jQuery Background image url getter setter

This simple jquery plugin adds the option to get / set the url of the background image of the jQuery selected elements. The main point of this is just simplifying the extraction of the background image's - location in clean url-format from the element's css properties, so it can be used for other images. This is done by a simple regular expression.

(function ($) {
	$.fn.backgroundImageUrl = function(options) {
		if (options){
			return this.each(function(){
				$(this).css('backgroundImage','url:('+options+')');
			});
		}else {
			var pattern = /url\(|\)|"|'/g;
			return $(this).css('backgroundImage').replace(pattern,"");
		}
	};
})(jQuery);
