jquery - How to order (sort) a <li> list with numeric content?

Question

I have a list as below that is created dynamically:

<ul>
  <li>20</li>
  <li>10</li>
  <li>5</li>
  <li>3</li>
  <li>32</li>
  <li>25</li>
  <li>6</li>
  <li>12</li>
  <li>8</li>
</ul>

Answer 1

var li = $('ul li');
li.sort(function(a, b) {
    if(parseInt($(a).text()) > parseInt($(b).text()))
        return 1;
    else return -1;
});
$('ul').empty().html(li);
