Change Input Masks Based on Selected Button in React JS

When building user interfaces, especially forms, developers often need to implement input masks to ensure that the data entered fits a certain format. This is particularly important for fields such as phone numbers, dates, or any other information that requires specific formatting. In this guide, we will explore how to dynamically change input masks based on the button a user selects in a React application.

The Problem

You have a grid of buttons, each corresponding to a different type of input mask you want to apply. For example, selecting a button could apply a mask for a phone number, while another could apply a mask for a date. You already have a basic setup with a state that tracks the selected button, but you need a more organized way to manage multiple masks.

Current Setup

You might be using something like this for your state:

You've successfully implemented a simple conditional check for two masks, like so:

The Solution: Use a Switch Statement

To tackle the issue with multiple masks, the solution lies in using a switch statement to determine which mask to apply based on the selectedButton. Here's how you can implement it:

Step 1: Define a Function to Return the Appropriate Mask

Create a function that takes the selected button as input and returns the corresponding mask:

Step 2: Use the Function in Your Input Mask Hook

Now, incorporate this function when setting up your input mask:

This way, the input mask will dynamically change based on which button the user selects.

Alternatively: Mapping Buttons to Masks

If you're looking for a more elegant solution or if your mask names can easily correlate with your button keys, you can use array indexing or mappings. Here’s an example approach where you might simply rename your masks or the buttons:

In this setup, the key selected directly corresponds to the respective mask, simplifying your code.

Conclusion

Implementing dynamic input masks based on user selection improves user experience and ensures that data is properly formatted. By using a switch statement or mapping, you can easily expand this functionality to accommodate as many masks as you need. Now you're equipped with a robust method to handle multiple input masks in your React applications!

Feel free to experiment with the setup to see what works best for your specific needs. Happy coding!
