More Examples

This example demonstrates how whitespace may interfare:

Try to get the node name of the last child node of "myDIV":

<div id="myDIV">
  <p>Looks like first child</p>
  <p>Looks like last Child</p>
</div>

<script>
let text = document.getElementById("myDIV").lastChild.nodeName;
</script>
Try it Yourself »

However, if you remove the whitespace from the source, there are no #text nodes in "myDIV":

<div id="myDIV"><p>First child</p><p>Last Child</p></div>

<script>
let text = document.getElementById("myDIV").lastChild.nodeName;
</script>
