jQuery remove all list items from an unordered list

Question

$("ul").empty() works fine. Is there some other error?

$('input').click(function() {
  $('ul').empty()
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul>
  <li>test</li>
  <li>test</li>
</ul>

<input type="button" value="click me" />

As noted by others, $('ul').empty() works fine, as does:

$('ul li').remove();

JS Fiddle demo.

This should work:

$("ul").html('')

$("ul").empty() should work and clear the childrens. you can see it here:

http://jsfiddle.net/ZKFA5/

   var ul = document.getElementById("yourElementId");

     while (ul.firstChild)
         ul.removeChild(ul.firstChild);
