Remove all Classes from an Element in JavaScript

There are several ways to remove all classes from an element in JavaScript. We will see more details in this guide first we have three methods below to remove all classes from an element that will see by one.

• classList
• removeAttribute
• className.

1. Using classList Method to remove classes:

The classList property provides methods to add, remove, or toggle classes on an element. To remove a class, we’ll specifically use the remove() method.

const element = document.getElementById('yourElementId');
element.classList.remove('classNameToRemove');

Explanation:

• Step 1: Select the target element using getElementById or another selection method.
• Step 2: Access the element’s classList property.
• Step 3: Use the remove() method of classList, passing the class name we want to remove as an argument.

This method is straightforward and efficient. However, keep in mind that it’s only available in modern browsers.

2. Using removeAttribute Method to modify classes:

The removeAttribute method enables us to remove attributes from an HTML element, including the class attribute.

const element = document.getElementById('yourElementId');
element.removeAttribute('class');

Explanation:

• Step 1: Identify the target element using getElementById or similar.
• Step 2: Apply the removeAttribute method, specifying 'class' as the attribute we want to remove.

This method is direct and works well for scenarios where you want to remove all classes associated with an element. However, it completely removes the class attribute, so use it judiciously based on your requirements.

3. Using className Property to remove or set desired classes:

The className property provides a straightforward way to modify or remove classes from an element.

Removing All Classes:

const element = document.getElementById('yourElementId');
element.className = '';

Explanation:

• Step 1: Identify the target element using getElementById or similar.
• Step 2: Assign an empty string '' to the className property of the element.

By setting className to an empty string, all classes associated with the element are effectively removed.

Assign a Single Class and Remove Others:

const element = document.getElementById('yourElementId');
element.className = 'desiredClass';

Explanation:

• Step 1: Locate the element using getElementById or a similar method.
• Step 2: Assign the className property to the desired class name that you want to set.

This method seems simple, but it replaces all existing classes with the specified ones.

Conclusion

In this blog, we explored three distinct methods for remove all classes from an element in JavaScript. We discussed the implementation of these methods using classList, removeAttribute, and the className property.

• classList: Offers specific methods like remove() to remove individual classes.
• removeAttribute: Directly removes the entire class attribute from the element.
• className Property: Provides flexibility by either removing all classes or assigning a single class while removing others.

Each method has its merits and specific use cases, allowing developers to choose the most suitable approach based on their requirements.
