Question

I need to be able to get the width of elements from an array

HTML

<div id="container">
  <ul>
     <li id="one">--------</li><br />
     <li id="two">----------------</li><br />
     <li id="three">-------</li><br />
  </ul>
</div>

JS

I know i can access the individual width’s like this

$('#one').width();

But in an array

var $array = $("#container li");

How do i access a specific width of the element by its index

e.g

$array[2].width(); //which causes error

Use eq :

$('#container li').eq(i)
