How to Activate a Link on Click and Deactivate Others in JavaScript

As web developers, we often encounter situations where we need to ensure that only one link can be active at a time while the others are inactive. If you've ever experienced this challenge, you're not alone! In this guide, we will explore how to activate a link on click and deactivate the others using JavaScript. This solution enhances user experience and maintains a clean interface.

While this setup enables the clicking of links, it does not remove the active status from previously clicked links.

The Solution

To correctly manage the activation and deactivation of links upon clicking, we can refine the initial code. The main idea is to loop through all links, remove the active state from each, and then apply the active class to the clicked link:

Store All Links: Retrieve all the anchors (<a>) within the parent element.

Add Click Event Listeners: For each link, bind a click event that will:

Prevent the default behavior of the link.

Remove the active class from all links.

Add the active class to the currently clicked link.

Here is how the complete code looks with these enhancements:
