Answer 1

Just use a class name instead of an id, you will be able to reuse the code you have just added but in this way.

 var list = $(".menu");

One advice, don't do the highlighting of the item menu with javascript, do it server-side, and you can add the "activating" class directly in the HTML of the LI.

Answer 2

This is the way to do it with Jquery

val elementList = $(".menu");
for (var i = 1; i <= list.length; i++) {
    elementList[i].attr("id", "menu" + i);
}

Answer 3

var i=0;
$('.menuHeader').each(function(){
    i++;
    var newID='menu'+i;
    $(this).attr('id',newID);
    $(this).val(i);
});
