How to Strike Through Text When Checking a Checkbox in React-Bootstrap

Creating a todo list application is a great way to learn React, and adding the feature of striking through text when a checkbox is checked makes it all the more engaging. Many developers, especially beginners, encounter challenges in managing the state and style of their components. In this post, we will address a common problem where users want their text to be visually marked as completed when the associated checkbox is checked — and how to achieve it neatly using React and React-Bootstrap.

The Problem

You might find yourself in a situation where you want to represent completed tasks with a strikethrough effect. Let's break down the issues involved in implementing this feature:

Checkbox Interactivity: The basic functionality is straightforward, but integrating it with visual indicators like strikethrough can lead to confusion about how to manage component states.

Use of Refs Incorrectly: Some developers attempt to manipulate DOM elements directly using refs instead of letting React manage the state, which causes coupling issues.

Understanding Controlled Components: It's essential to grasp the concept of controlled components in React for better state management.

The Solution: Controlled Components Pattern

To achieve the desired effect without unnecessary complexity, we will utilize controlled components. This practice keeps the checkbox state and the visual representation tightly synced, ensuring a responsive and reliable user experience.

Step 1: Set Up Your Component

We’ll revise your component to implement a more conducive approach using hooks. Instead of relying on refs to manage the text decoration, we'll handle it using React's state and props.

Here's the revised code utilizing a controlled component pattern:

Step 2: Explanation of the Code

Separate Component for Each Checkbox: We create a FormCheckBox component that maintains its own checked state. This encapsulation allows for cleaner management of each checkbox's state.

Dynamic Styles: The styles object dynamically changes according to the checkbox state, creating an interactive user experience where the text's decoration changes in real-time.

Event Handling: The toggleCheck function updates the local checked state whenever the checkbox is clicked, making the component re-render and show the appropriate strikethrough styling.

Step 3: Maintaining Overall State

If you want to extend functionality to track the state of all checkboxes across multiple items, you can maintain a single state object in the main App component. This lets you record the check state in an array and render each checkbox appropriately based on their completion status.

Conclusion

By using controlled components and proper state management within React, you can efficiently manage checkbox interactions and their corresponding styles in a todo list application. This not only improves your code quality but also enhances user experience remarkably.

We hope you found this guide helpful! The next time you work on a todo list with React-Bootstrap, remember to leverage controlled components for a seamless interaction!
