jQuery - rule for “does not contain element”

Question

I want to create a rule to target the a element in the following:

   

      Root Me         


        

Answer 1

$('#root a').click(function(e) {
    if ( $(this).parents('ul').length > 1 ) {
       e.preventDefault(); // cancel action for anchors inside of #root who have multiple parent list elements 
    }
});

Change logic per requirement.
