TypeScript element.classList.remove() method (with examples)

In the realm of web development, manipulating elements dynamically is a common task. TypeScript, being a superset of JavaScript, offers a more structured approach to this. One of the fundamental tasks in manipulating element classes involves the element.classList.remove() method. This tutorial will guide you through its use in TypeScript with practical examples.

Understanding the DOM and classList

Before we dive into the remove() method, it’s crucial to understand what the DOM (Document Object Model) and classList are. The DOM represents the document structure, and classList is a read-only property that returns a live DOMTokenList collection of the class attributes of the element. It provides methods to add, remove, and toggle CSS classes on an element.

Basic Usage

To start with, let’s see how you can simply remove a class from an element using the remove() method:


In this example, if the element with the ID ‘myElement’ has the class ‘my-class’, it will be removed. If the class does not exist, the method will not throw an error; it simply does nothing.

Removing Multiple Classes

The remove() method allows the removal of multiple classes at once:

document.getElementById('anotherElement').classList.remove('first-class', 'second-class');

This example demonstrates removing more than one class from an element. It’s a straightforward way to clean up your element’s classes.

Conditional Removal

Sometimes, you might want to remove a class based on some condition. TypeScript’s type safety and logic handling amplify the effectiveness of such operations:

if (condition) {

This snippet shows how you could conditionally remove a class from an element. The condition could be any logical condition relevant to your scenario.

Advanced Scenario: Interaction with Other Methods

The classList API is not just about removing classes; it’s a versatile tool. Here’s how you can combine remove() with add() and contains() to create more dynamic interactions:

const myElement = document.getElementById('dynamicElement');
if (myElement.classList.contains('active')) {
} else {

This code checks if the element has the ‘active’ class. If yes, it removes it and adds ‘inactive’. If not, it does the opposite. This pattern is useful for toggling states in response to user actions.

Working with Angular

In a TypeScript-centric environment like Angular, you may more often manipulate classes through binding. However, direct class manipulation using classList.remove() can still be handy, especially when dealing with dynamic or conditional classes that are more complex:

  selector: 'my-component',
  template: `Toggle Class`,
export class MyComponent {
  @ViewChild('myDiv') myDiv: ElementRef;

  toggleClass() {
    const classList = this.myDiv.nativeElement.classList;
    if (classList.contains('hidden')) {
    } else {

This Angular example shows how to use classList directly in a component to toggle a class. It demonstrates the synergy between TypeScript and framework-specific features for dynamic class manipulation.


The element.classList.remove() method is a powerful tool in the arsenal of web developers working with TypeScript. Whether you’re working directly with the DOM in a vanilla TypeScript setting or within frameworks like Angular, understanding how to manipulate element classes can greatly improve the interactivity and responsiveness of your applications. With the foundation laid out in this tutorial, you can explore more sophisticated ways to enhance your web applications.
