How to Allow 10-Digit Number Validation in Vuetify Text Fields?

Setting Up Vuetify Text Field for 10-Digit Number Validation

When it comes to allowing 10-digit number validation in Vuetify text fields, the process involves a few key steps. Let's start by setting up a Vuetify text field specifically designed to capture 10-digit phone numbers within a Vue.js application.

Vuetify Text Field Validation Rule for 10-Digit Numbers

<v-container>
    <h3>Vuetify Text Field Allow 10 digit Number</h3>
    <v-form @submit.prevent="register">
        <v-text-field v-model="phoneNumber" label="Phone Number" :rules="phoneNumberRules"></v-text-field>
    </v-form>
</v-container>

Applying Validation Rules to the Vuetify Text Field

The heart of this validation lies in the validatePhoneNumber method defined in the JavaScript code. This method ensures that the input provided is indeed a 10-digit number. If the input is empty or does not match the required format, an appropriate error message is displayed, guiding the user to enter a valid 10-digit phone number

 <script>
        new Vue({
            el: '#app',
            vuetify: new Vuetify(),
        data() {
                return {
                    phoneNumber: "",
                };
            },
            methods: {
                validatePhoneNumber(value) {
                    if (!value) return "Phone number is required";
                    if (!/^\d{10}$/.test(value)) return "Phone number must be a 10-digit number";
                    return true;
                },
            },
            computed: {
                phoneNumberRules() {
                    return [
                        (v) => this.validatePhoneNumber(v) || "Invalid phone number",
                    ];
                },
            },
        });
    </script>

To enforce the 10-digit number validation, the phoneNumberRules computed property is utilized. This property applies the custom validation logic to the Vuetify text field. If the user enters an invalid phone number, an error message stating "Invalid phone number" is displayed, ensuring data accuracy in your application
