How to check if the element is not the first-child?

Question

How do you know if the current element is not the first-child?

It should work with $(this), for example:

$("li").click(function(e) {     if (/* $(this) is not the first-child */)     {         /* do something */     } }); 

Answer 1

You can do this just to test an element if it's the first child: $(this).is(':first-child'). Other selectors like :last-child would work too.
