How to Toggle Button State in React with One Click

React has become one of the leading libraries for building user interfaces due to its flexibility and ease of use. One common feature you'll encounter is the need for buttons that change their appearance and text when clicked, and revert back to their original state upon a second click. This guide will guide you through an effective way to implement this functionality in React.

The Problem: Changing Button States

Imagine you have a button labeled "A". When clicked, you want it to change to "B", both in appearance and text. After another click, it should return to its original state, displaying "A" once more. This can enhance user interaction and make your application more dynamic. So, how do we accomplish this in React?

The Solution: Using useState Hook

To achieve the toggle functionality, we can take advantage of the useState hook from React, which allows you to manage component states efficiently. Here's how to do it step by step:

1. Setting Up State Variables

First, you'll need to set up your state variables, which will hold the class for your button's styling and the button's text. Here’s how you can define these states:

2. Creating the Change Handler

Next, you need to create a function that will change these states when the button is clicked. Instead of setting them directly to new values, you can access the previous state to toggle between "A" and "B". This can be done like this:

This function checks the current state of classColor and classText. If it's currently set to "A" or styles.classAButton, it switches to "B" or styles.classBButton, and vice versa.

3. Button Component Implementation

Now you can implement your button with the onClick event linked to your change handler. Here’s how the button might look in your component:
