How to increase id div value?

I have a task to set the menu as selected. For this, I use a dynamic identifier. Therefore, I want to increase it in relation to the choice

My code

<div class="menuHeader ui-corner-top" id="menu"+ i>
    <span><a href="#" onclick="Home()">Home</a></span>
</div>
<div class="menuHeader ui-corner-top" id="menu"+ i>
    <span><a href="#" onclick="NewTransaction()">New Transaction</a></span>
</div>
<div class="menuHeader ui-corner-top" id="menu"+ i>
    <span><a href="#" onclick="Portfolio()">Portfolio</a></span>
</div>

javascript

$(document).ready(function () {
             alert(document.URL);
             var list = $("#menu");
             for (var i = 1; i <= list.length; i++) {
                 list[i].innerHTML = i;
             }
             var str = document.URL.toLowerCase().indexOf("portfolio/index");
             alert(str);
             if (str >= 0) {
                 $('#menu').addClass("menuHeaderActive");
             }
         });

This is the way to do it using jQuery

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