Remove the all classes from an element using JavaScript

In this tutorial, we are going to learn about how to remove the all classes from an HTML element using JavaScript with the help of examples.

Consider, we have a following html in our page.

<div class="container center red" id="left-div">
   some text
</div>

Now, we need to remove the all class names from a div element.

Removing all classes from an element

To remove the all classes from an element, we need to set the element className property to an empty string ('').

Here is an example:

<div class="container center red" id="left-div">
   some text
</div>

JavaScript:

const div = document.getElementById('left-div');
div.className = '';

In the example above, we have removed all class names from a div element.

Using removeAttribute() method (alternative approach)

To remove the all classnames from a element, we can use the removeAttribute() method in JavaScript.

The removeAttribute() method takes the attribute name (ex: class, id etc) as an argument and removes it from the element.

Here is an example:

const div = document.getElementById('left-div');

// it removes the all classes from a div elementdiv.removeAttribute('class');
