Add jQuery support for outerHTML, with feature detection

gistfile1.js

// Add support for outerHTML, which in FF was only added at version 11.
// Only use elem.outerHTML once support for FF<11 is no longer needed.
(function($){
	$.fn.outerHTML = function() {
		var a = this.get(0).outerHTML;
		return a ? a : $('<p/>').append(this.clone()).html();
	}
})(jQuery);
