How to order (sort) a <li> list with numeric content?
Below should do the trick:
$(function() {
$('button').click(function() {
var liContents = [];
$('ul li').each(function() {
liContents.push(parseInt($(this).text(), 10));
});
liContents.sort(numOrdDesc);
$('ul li').each(function() {
$(this).text(liContents.pop());
});
});
});
function numOrdDesc(a, b) {
return (b - a);
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<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>
<button>Sort</button>
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);
There are jQuery plugins to handle this as well. Check out TinySort
