How do I get Index of Listview?

I can the correct index of listview using this code:

$('#listview').on('click', 'li', function() {
    alert( $(this).index());
});

This returns the correct index.

However if using this code, it always returns 0:

$('#listview').on('click', 'div', function() {
    alert( $(this).index());
});

I use second code to differentiate the click event among different divs.

The index gives you the position of the element relative to its siblings in the HTML tree. if your div is within the li and your HTML looks like this

<ul id="listview">
   <li><div>First div for click handler</div></li>
   <li><div>Second div for click handler</div></li>
</ul>

Then 0 is the correct index for any div in the listview. Maybe you need something like this

$(this).closest('li').index();

in your click handler.
