How to get the Parent Node of DOM Element in JavaScript

JavaScript has a lot of built-in functionality that makes working with the DOM on the web easy.

When you are working with DOM elements, a common thing you will want to do is get the parent node of an element.

In this post, we'll learn how to get the parent node of a DOM element in JavaScript.

How to get the parent node of a DOM element in JavaScript

Because of HTML's DOM-like structure, elements are arranged in a tree. This means that each element has a parent node, and each element can have multiple child nodes.

First, let's look at the HTML we'll be working with:

	<div class="parent">
    <div class="child"></div>
</div>

Let's say we want to get the parent node of the child element. We can do this by first querying the DOM for the child element:

	const child = document.querySelector(".child");

console.log(child);

	<div class="child"></div>

Then, we can get the parent node of the child element by using the parentNode property:

	const child = document.querySelector(".child");

const parent = child.parentNode;

console.log(parent);

	<div class="parent">
    <div class="child"></div>
</div>

The only element that does not have a parent node is the document element. This is because the document element is the root of the DOM tree.

Other than the document element, every other element has a parent node and so when you use the parentNode property, you will always get an element back.

Conclusion

In this post, we learned how to get the parent node of a DOM element in JavaScript.

Simply query the DOM for the element you want to get the parent node of, and then use the parentNode property to get the parent node.
