get last element of array in input tag with jquery

I have

<div id="exp">
  <input type="hidden" name="sum[]" value="1" />
  <input type="hidden" name="sum[]" value="2" />
  <input type="hidden" name="sum[]" value="3" />
  <input type="hidden" name="sum[]" value="4" />
</div>

And I want in jquery get the value of the last element of the array. I've tried:

alert(sum[sum.length-1]);

But shows me 'undefined'. What am I doing wrong?

You can use this:

var lastValue = $("#exp input:last").val();

This uses a jQuery selector to find the last input element that is a child of #exp and get its value.

You can see it work here: http://jsfiddle.net/jfriend00/Lh7sJ/
