JavaScript Get the Parent Element parentNode

Summary: in this tutorial, you will learn how to get the parent node of an element by using the JavaScript parentNode attribute of the Node object.

Introduction to parentNode attribute

To get the parent node of a specified node in the DOM tree, you use the parentNode property:

let parent = node.parentNode;

Code language: JavaScript (javascript)

The parentNode is read-only.

The Document and DocumentFragment nodes do not have a parent. Therefore, the parentNode will always be null.

If you create a new node but haven’t attached it to the DOM tree, the parentNode of that node will also be null.

JavaScript parentNode example

See the following HTML document:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>JavaScript parentNode</title>
</head>
<body>
<div id="main">
<p class="note">This is a note!</p>
</div>

<script>
let note = document.querySelector('.note');
console.log(note.parentNode);
</script>
</body>
</html>

Code language: HTML, XML (xml)

The following picture shows the output in the Console:

How it works:

  • First, select the element with the .note class by using the querySelector() method.
  • Second, find the parent node of the element.

Summary

  • The node.parentNode returns the read-only parent node of a specified node or null if it does not exist.
  • The document and DocumentFragment do not have a parent node.
