Changing Background and Text Colors in VueJS 3 on Click Events

When working with VueJS, enhancing the user experience is often about interactivity. One common requirement is changing the background and text color of a container when it is clicked. If you've found yourself wanting to implement this feature in VueJS 3, you're in the right place! In this post, we will discuss how to achieve this functionality using a simple and effective approach.

The Problem

You have an existing VueJS application with a layout that contains several containers. Each container is supposed to perform a specific function, like managing users or settings. You want to enhance the user interaction by changing the background and text colors of these containers when a user clicks on them. Basically, you want to make the interface more dynamic and visually engaging.

The Solution

Step 1: Set Up a Reactive State

To manage the class of your container dynamically, we will create a reactive state in your Vue component. This state will hold the class name that you want to apply based on the user's actions.

Add the Reactive Variable:

Here, desiredClass is a reactive ref that will change based on the user's clicks.

Step 2: Bind the Class to Your Container

Next, you will need to bind this reactive state to the class attribute of your container. This way, whenever desiredClass is updated, the container will reflect the desired styles automatically.

Bind the Class:

Notice the use of :class, which binds desiredClass. This binding allows Vue to reactively update the styles of the container.

Step 3: Implement the Change Handler

Now, you will implement a method that will modify the desiredClass variable based on user interaction. For example, when a user clicks on a specific container, the background and text colors can be changed accordingly.

Create the Change Handler:

In this example, when the container receives a click, desiredClass updates to reflect a new background color (blue) and text color (white). Adjust these color classes as you see fit for your application's design.

Step 4: Handling Multiple Containers

If you have multiple containers that you wish to style differently on click, you can expand this method by passing the intended class name or state to your changeBackgroundColor method.

Handle Different Clicks:

Then in your HTML, you can call the function with different parameters based on the container clicked:

This ensures each container can customize its styles independently based on user interaction.

Conclusion

Changing the background and text colors dynamically in VueJS 3 is a straightforward process that greatly enhances the interactivity of your application. By employing Vue's reactive capabilities, you can build a more engaging interface effectively. Whether you are managing different functionalities or simply enhancing aesthetics, the ability to react to user clicks by modifying style properties adds a lot of value to your application.

Now, take these steps and add some color and excitement to your VueJS project! Happy coding!
