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:
HTML<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:
JAVASCRIPTconst child = document.querySelector(".child");
console.log(child);
HTML<div class="child"></div>
Then, we can get the parent node of the child element by using the parentNode property:
JAVASCRIPTconst child = document.querySelector(".child");
const parent = child.parentNode;
console.log(parent);
HTML<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.
