Instantiating Multiple Material Design Components in JavaScript

When working with Material Design components, you typically encounter various situations where you need to instantiate them. This can feel straightforward when dealing with a single component, but the challenge arises when you're required to handle multiple components simultaneously.

In this guide, we’ll explore the solution to this common problem: how to effectively instantiate multiple Material Design components using JavaScript, specifically focusing on the MDCRipple component.

The Problem: Instantiating Multiple Components

Let's break down the challenge. You might be familiar with the following example for instantiating a single MDCRipple component:

This snippet efficiently adds a ripple effect to one icon-button. However, what if you have multiple buttons? Following the Material Design Components (MDC) documentation, one might attempt to use querySelectorAll like this:

Unfortunately, this approach doesn’t allow you to set properties such as iconButtonRipple.unbounded = true; on all instantiated components.

The Solution: Correctly Instantiating Multiple Components

Fortunately, there are cleaner and more efficient ways to instantiate multiple MDCRipple components. Below are a couple of methods that will help you achieve this task effortlessly:

Method 1: Using Arrow Functions with Spread Syntax

Explanation:

querySelectorAll grabs all elements with the class .mdc-icon-button.

The ... (spread syntax) creates an array from the NodeList returned by querySelectorAll.

Using .map(), we create a new MDCRipple instance for each element and immediately set its unbounded property to true.

Method 2: Setting Properties After Instantiation

Explanation:

Similar to the first method, we select all the buttons and create an array of MDCRipple instances.

We then iterate through the ripples array with .forEach() to set the unbounded property to true on each instance.

Conclusion

Both methods illustrated above allow you to efficiently instantiate multiple MDCRipple components while ensuring that the necessary configurations, such as the unbounded feature, are applied to all instances. Choose the method that feels most comfortable for your coding style!

By using these techniques, you streamline your code, making it more maintainable and effective for handling multiple Material Design components in your web applications. Now, go ahead and utilize these methods in your projects to enhance your UI with Material Design's ripple effects.
