Unlock the Power of Form Validation with Vuetify

Improving User Experience with Form Validation

When it comes to online forms, a seamless user experience is crucial. Unfortunately, many forms fall short when it comes to providing adequate feedback during error-handling. This can lead to frustration and abandonment. By implementing quality form validation, we can significantly enhance the user experience.

Getting Started with Vue.js and Vuetify

To begin, let’s create a new Vue.js project using Vue CLI. If you don’t have Vue CLI installed, simply run the following command:

npm install -g @vue/cli

Once installed, create a new project by running:

vue create vuetify-form-validation

Choose the default preset to get started.

Next, add Vuetify to your project by running:

vue add vuetify

Select the default preset.

Building the Registration Form Interface

Our registration form will consist of five fields: First Name, Last Name, Email, Password, and Re-type Password. We’ll use Vuetify’s grid components to divide the page into two columns. Create a new file called RegistrationForm.vue and add the following code:

<template>
  <v-container fluid>
    <v-row>
      <v-col cols="6" class="purple" style="height: 100vh;">
        <h1>Registration Form</h1>
      </v-col>
      <v-col cols="6" class="text-center" style="height: 100vh;">
        <h1>Register Now!</h1>
        <p>Please fill out the form below.</p>
        
      </v-col>
    </v-row>
  </v-container>
</template>

Implementing Form Validation

Now, let’s add our form fields and implement validation using Vuetify’s v-form component. Add the following code inside the right column:

<form ref="form">
  <v-text-field
    v-model="firstName"
    :rules="nameRules"
    label="First Name"
    required
  ></v-text-field>

  <v-text-field
    v-model="lastName"
    :rules="nameRules"
    label="Last Name"
    required
  ></v-text-field>

  <v-text-field
    v-model="email"
    :rules="emailRules"
    label="Email"
    required
  ></v-text-field>

  <v-text-field
    v-model="password"
    :rules="passwordRules"
    label="Password"
    type="password"
    required
  ></v-text-field>

  <v-text-field
    v-model="rePassword"
    :rules="passwordRules"
    label="Re-type Password"
    type="password"
    required
  ></v-text-field>

  <v-checkbox
    v-model="terms"
    :rules="termsRules"
    label="I agree to the terms and conditions"
    required
  ></v-checkbox>

  <v-btn @click="submitForm">Register</v-btn>
</form>

Validating Form Fields

Next, we’ll define our validation rules for each field. In the script tag, add the following code:

export default {
  data() {
    return {
      firstName: '',
      lastName: '',
      email: '',
      password: '',
      rePassword: '',
      terms: false,
      nameRules: [v =>!!v || 'Name is required'],
      emailRules: [v => /.+@.+\..+/.test(v) || 'Invalid email'],
      passwordRules: [
        v =>!!v || 'Password is required',
        v => /(?=.*[a-z])/.test(v) || 'Must contain lowercase letter',
        v => /(?=.*[A-Z])/.test(v) || 'Must contain uppercase letter',
        v => /(?=.*\d)/.test(v) || 'Must contain number',
        v => /(?=.*[!@#$%^&*()])/.test(v) || 'Must contain special character'
      ],
      termsRules: [v =>!!v || 'Terms must be accepted']
    }
  },
  methods: {
    submitForm() {
      this.$refs.form.validate()
    }
  }
}
