How to Dynamically Change CSS Classes on Tab Click Using JavaScript and jQuery

Have you ever faced a situation where clicking a tab on your website doesn’t reflect the expected changes in style? This happens when you're trying to add a CSS class dynamically in your web application without seeing any visible change. In this guide, we will walk through a common problem related to dynamic CSS class manipulation using jQuery, and how to solve it effectively.

The Problem

You have a code snippet that allows users to click on different company tabs, and you want to highlight the currently selected tab by adding a special CSS class (action). However, upon clicking a tab, you find that the tab does not change color as intended. Instead, it seems like the previously selected tab retains the action class. This is frustrating because it hinders user experience.

Code Breakdown

Let’s take a look at the HTML, CSS, and JavaScript involved in your implementation:

Diagnosis of the Issue

In the JavaScript code, when a tab is clicked, you use the jQuery selector to add the action class to all links with the Company-SwitchURL-link class. This means every tab will receive the action class, causing the one that should be highlighted to simply appear like others, especially when there’s a refresh triggered by a function that pulls new data.

The Solution

To resolve this issue, you need to make a couple of adjustments in your JavaScript code. Specifically, you should ensure that you are only applying the action class to the clicked tab and removing it from all others.

Updated JavaScript Code

Here’s how you can correct this:

Key Changes Explained

Remove class from all links: The line $(".Company-SwitchURL-link").removeClass("action"); ensures that before adding the class to the currently clicked tab, all others will have it removed, preventing multiple tabs from being highlighted at once.

Adding class to the clicked tab: Using $(this).addClass("action"); targets only the clicked tab, which is exactly what you need to dynamically highlight it.

Enhance Your CSS

You may also want to review and update your CSS to ensure it clearly reflects visual changes for the action class:

Conclusion

By making a few simple adjustments to how you manage CSS classes, you can create a more intuitive and dynamic user experience on your website. Remember to always ensure that your modifications target the intended elements specifically, which will simplify updates and enhance interactions for users. Now you can enjoy seamless switching between company tabs with visual feedback!
