Validating Email Fields in Vuetify: A Step-by-Step Guide

In this template, we have a Vuetify container containing a form with an input field for the email address. We also have an alert component to display validation feedback.

<v-container>
    <h3>Vuetify Validate Email Address</h3>
    <v-form @submit.prevent="submitForm">
        <v-alert v-if="feedback" :type="feedback.type">{{ feedback.message }}</v-alert>
        <v-text-field v-model="email" label="Email"></v-text-field>
        <v-btn type="submit" color="success" label="Submit">Submit</v-btn>
    </v-form>
</v-container>

JavaScript Logic

Now, let's implement the JavaScript logic to handle email validation and form submission

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

    createApp({
        data() {
            return {
                email: "",
                feedback: null,
            };
        },
        computed: {
            emailError() {
                return !this.email ? ["Email is required"] : this.email.match(/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/) ? [] : ["Invalid email format"];
            },
        },
        methods: {
            submitForm() {
                this.feedback = !this.emailError.length ? { type: 'success', message: 'Email is valid.' } : { type: 'error', message: this.emailError[0] };
            },
        },
    })
        .use(vuetify)
        .mount('#app');
</script>

This JavaScript code defines a Vue.js app with the following key features:

Data properties for the email input and feedback.
A computed property emailError to check the validity of the email address.
A method submitForm to handle form submission and provide feedback
