How to write "if not class" jQuery selector?

Question

I want to do something with var p:

var p = $("li:last"); 

But I don't want to do anything if there is a certain Class appended. I tried :not like this:

var p = $("li:last:not(.Class)"); 

This doesn't work. How can I exclude .Class in my var?

Answer 1

var p = $("li:last").not(".Class");
