<!DOCTYPE html>

<body>

<ul id="myList">
  <li>Coffee</li>
  <li>Tea</li>
</ul>

<p>Click the button to see if the ul element has any child nodes.</p>

<button onclick="myFunction()">Try it</button>

<p>Try removing the child nodes of the list element, and the result will be false instead of true.</p>

<p><strong>Note:</strong> Whitespace inside a node is considered as text nodes, so if you leave any white space or line feeds inside an element, that element still has child nodes.</p>

<script>
function myFunction() {
  var list = document.getElementById("myList").hasChildNodes();
  window.alert(list);
}
</script>
