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

Keep it simple, use the DOM

$("li").click(function(e) {

    if (this.previousSibling != null)
    {
        /* do something */
    }

});
