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) {
          


        

Answer 1

$("li").click(function(e) {
   if ($(this).index != 0 )
  {
      /* do something */
   }
});
