Why form binding matters in Vue - See It in Action

Why form binding matters

📖 Scenario: You are building a simple contact form for a website. The form needs to collect a user's name and email address. To make the form interactive and easy to use, you will use Vue's form binding feature.

🎯 Goal: Create a Vue component that binds form input fields to data properties. This will allow the form to update the data automatically as the user types, showing the live values below the form.

📋 What You'll Learn

Create a Vue component using the Composition API with <script setup>.

Set up reactive data properties for name and email.

Bind the input fields to these data properties using v-model.

Display the current values of name and email below the form.

💡 Why This Matters

🌍 Real World

Form binding is essential for interactive web forms where user input needs to be captured and used immediately, such as contact forms, surveys, and login pages.

Understanding form binding in Vue is a key skill for frontend developers building user-friendly and accessible web applications.

1

Set up reactive data properties

Create a Vue component with <script setup> and import ref from 'vue'. Then create two reactive variables called name and email initialized to empty strings.

Vue

// Your code here

Need a hint?

Use ref('') to create reactive variables for name and email.

2

Add the form inputs with v-model binding

Below the <script setup>, add a <template> section. Inside it, create a form with two input fields: one for name and one for email. Bind each input's value to the corresponding reactive variable using v-model.

Vue

import { ref } from 'vue'

const name = ref('')
const email = ref('')



  

Need a hint?

Use v-model="name" and v-model="email" on the input fields to bind them.

3

Display the live values below the form

Inside the <template> but below the form, add two paragraphs that show the current values of name and email using Vue's mustache syntax {{ }}.

Vue

import { ref } from 'vue'

const name = ref('')
const email = ref('')



  
    Name:
    

    Email:
    
  
  

Need a hint?

Use {{ name }} and {{ email }} inside paragraphs to show live data.

4

Add accessibility and form structure improvements

Add aria-label attributes to both input fields with values "Name input" and "Email input" respectively. Also, wrap the form in a <section> with a heading <h2> that says "Contact Form".

Vue

import { ref } from 'vue'

const name = ref('')
const email = ref('')



  
  

Need a hint?

Use aria-label on inputs for accessibility and wrap the form in a <section> with a heading.
