This line of code attempts to retrieve two elements simultaneously, which is not supported. The getElementById method accepts only one argument at a time.

Solution: Defining a Function to Handle Multiple Elements

To efficiently manage multiple buttons, we can create a function that takes an array of button configurations (IDs, icons, and text) and sets up event listeners for each button. This approach is clean, reusable, and eliminates redundancy.

Step-by-Step Implementation

Create an Array of Button Configurations: This will store the IDs, the icons, and the text you want to display when the buttons are clicked.

Create a Function to Add Click Handlers: This function will loop through the array and set up the necessary event listeners.

Call the Function with Your Button Configurations.

Here’s how it looks in practice:

Conclusion

Using a structured approach to manage multiple button elements in JavaScript allows for cleaner code and greater efficiency. By creating a function to handle button clicks based on an array of configurations, you can easily expand your functionality in the future without cluttering your codebase. This not only helps with readability but also aids in easier debugging and maintenance.

So next time you’re faced with multiple IDs, remember this solution!
