Email Validator using HTML, CSS and JavaScript – Coding Torque

Share your love

Hello Guys! Welcome to Coding Torque. In this blog, I’m going to explain to you how to make an Email Validator using HTML, CSS and JavaScript. You can use this effect on your website/portfolio to showcase any skills/features. This will be a step-by-step guide. Let’s get started 🚀.

Before we start, here are some JavaScript Games you might like to create:

1. Snake Game using JavaScript

2. 2D Bouncing Ball Game using JavaScript

3. Rock Paper Scissor Game using JavaScript

4. Tic Tac Toe Game using JavaScript

5. Whack a Mole Game using JavaScript

 

I would recommend you don’t just copy and paste the code, just look at the code and type by understanding it.

 

HTML Code 

Starter Template

<!doctype html>
<html lang="en">

<head>
    <!-- Required meta tags -->
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <title>Email Validator using JavaScript - @codingtorque</title>
</head>

<body>
    <!-- Further code here -->
</body>

</html>

Paste the below code in your <body> tag

<div class="email-input">
    <input type="email" placeholder="aaron@gmail.com">
    <svg viewBox="0 0 18 18">
        <path d="M11.5,10.5 C6.4987941,17.5909626 1,3.73719105 11.5,6 C10.4594155,14.5485365 17,13.418278 17,9 C17,4.581722 13.418278,1 9,1 C4.581722,1 1,4.581722 1,9 C1,13.418278 4.581722,17 9,17 C13.418278,17 17,13.42 17,9"></path>

const regex = new RegExp(
    '^(([^<>()[\\]\\\\.,;:\\s@\\"]+(\\.[^<>()[\\]\\\\.,;:\\s@\\"]+)*)|' +
    '(\\".+\\"))@((\\[[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\.[0-9]{1,3}\\])' +
    '|(([a-zA-Z\\-0-9]+\\.)+[a-zA-Z]{2,}))$'
);

document.querySelectorAll('.email-input').forEach(container => {

    let input = container.querySelector('input')

    input.addEventListener('keyup', e => container.classList.toggle('valid', regex.test(input.value)))

});
