Vuetify Change Button Color if Button active or selected

In this tutorial, we will explore how to change the color of Vuetify buttons when they are active or selected. We'll be using Vue.js and Vuetify to create a simple interface with three buttons. The button that is clicked will change color to indicate its active state. This functionality is achieved by dynamically adding a CSS class to the buttons

How to Change Button Color in Vuetify When the Button is Active or Selected?

The HTML Structure consists of a Vuetify container containing three buttons, each with a click event listener. The buttons have a default primary color and a dynamic class binding to change their color when they are active

Changing Vuetify Button Color When Active or Selected

<v-container>
    <h3>Vuetify Change Button Color if Button active or selected</h3>
    <v-btn @click="changeActiveButton(1)" color="primary" :class="{ 'active-button': activeButton === 1 }">Button
        1</v-btn>
    <v-btn @click="changeActiveButton(2)" color="primary" :class="{ 'active-button': activeButton === 2 }">Button
        2</v-btn>
    <v-btn @click="changeActiveButton(3)" color="primary" :class="{ 'active-button': activeButton === 3 }">Button
        3</v-btn>

</v-container>

Run

In the JavaScript code, we use Vue.js and Vuetify to create our application. We set up a Vue app and define the 'activeButton' data property, initialized to 'null'. This property stores the currently active button number. We also define a method called 'changeActiveButton', which is called when a button is clicked.

The JavaScript Code

<script type="module">
    const { createApp } = Vue;
    const { createVuetify } = Vuetify;
    const vuetify = createVuetify();

    createApp({
        data() {
            return {
                activeButton: null,
            };
        },
        methods: {
            changeActiveButton(buttonNumber) {
                if (this.activeButton === buttonNumber) {
                    // If the clicked button is already active, deactivate it
                    this.activeButton = null;
                } else {
                    // Deactivate the previously active button
                    this.activeButton = buttonNumber;
                }
            },
        },

    })
        .use(vuetify)
        .mount('#app');
</script>

The 'changeActiveButton' method takes a 'buttonNumber' argument to identify which button was clicked. If the clicked button is already active, we set 'activeButton' to 'null' to deactivate it. If a different button is clicked, we update 'activeButton' with the 'buttonNumber', effectively deactivating the previously active button and activating the newly clicked one.

By using the ':class' directive, we apply the 'active-button' CSS class to the buttons when 'activeButton' is equal to their respective button numbers. This class is responsible for changing the button's color when active.
