How to remove all child elements of a DOM node in JavaScript

0 votes

I have the following HTML:

<p id="foo">
    <span>hello</span>
    <div>world</div>
</p>

And I grab the node I want like so:

var myNode = document.getElementById("foo");

How could I remove the children of foo so that just <p id="foo"></p> is left?

Could I just do:

myNode.childNodes = new Array();

or should I be using some combination of removeElement?

How would I go about removing all of the child elements of a DOM node in JavaScript?

Hello @kartik,

Use modern Javascript, with remove!

const parent = document.getElementById("foo")
while (parent.firstChild) {
    parent.firstChild.remove()
}

This is a newer way to write node removal in ES5. It is vanilla JS and reads much nicer than relying on parent.

Hope it helps!!
Thank you!!
