4. Make the entire LI clickable

This trick is very useful when you're using UL list to make a menu. What it does is, when you click on the LI area (outside of the link), it will search for the url in the anchor tag and execute the link:

	$("ul li").click(function(){
	  //get the url from href attribute and launch the url
	  window.location=$(this).find("a").attr("href"); return false;
	});
