This tutorial will teach us how to develop a Movie Seat Booking Project with plain JavaScript, HTML, and CSS.
Movie Seat Booking
Display movie choices and seats in a theatre to select from to purchase tickets.
Project Specifications
- Display UI with movie select, screen, seats, legend & seat info
- Users can select a movie/price
- Users can select/deselect seats
- User can not select occupied seats
- The number of seats and price will be updated
- Save seats, movies, and prices to local storage so that UI is still populated on refresh.
Movie Seat Booking Project with JavaScript, HTML and CSS
Create a folder called movie-seat-booking as the project workspace, and we will create all the project files in this folder.
1. index.html
Let's create index.html and add the following code to it:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta http-equiv="X-UA-Compatible" content="ie=edge" />
<link rel="stylesheet" href="style.css" />
<title>Movie Seat Booking</title>

<div class="movie-container">

<p class="text">

id="total"

</p>
<script src="script.js"></script>
</body>
</html>
2. script.js
Let's create a JavaScript file named script.js and add the following JavaScript code to it:
const container = document.querySelector('.container');
const seats = document.querySelectorAll('.row .seat:not(.occupied)');
const count = document.getElementById('count');
const total = document.getElementById('total');
const movieSelect = document.getElementById('movie');
populateUI();
let ticketPrice = +movieSelect.value;
// Save selected movie index and price
function setMovieData(movieIndex, moviePrice) {
localStorage.setItem('selectedMovieIndex', movieIndex);
localStorage.setItem('selectedMoviePrice', moviePrice);
}
// Update total and count
function updateSelectedCount() {
const selectedSeats = document.querySelectorAll('.row .seat.selected');
const seatsIndex = [...selectedSeats].map(seat => [...seats].indexOf(seat));
localStorage.setItem('selectedSeats', JSON.stringify(seatsIndex));
const selectedSeatsCount = selectedSeats.length;
count.innerText = selectedSeatsCount;
total.innerText = selectedSeatsCount * ticketPrice;
setMovieData(movieSelect.selectedIndex, movieSelect.value);
}
// Get data from localstorage and populate UI
function populateUI() {
const selectedSeats = JSON.parse(localStorage.getItem('selectedSeats'));
if (selectedSeats !== null && selectedSeats.length > 0) {
seats.forEach((seat, index) => {
if (selectedSeats.indexOf(index) > -1) {
seat.classList.add('selected');
}
});
}
const selectedMovieIndex = localStorage.getItem('selectedMovieIndex');
if (selectedMovieIndex !== null) {
movieSelect.selectedIndex = selectedMovieIndex;
}
}
// Movie select event
movieSelect.addEventListener('change', e => {
ticketPrice = +e.target.value;
setMovieData(e.target.selectedIndex, e.target.value);
updateSelectedCount();
});
// Seat click event
container.addEventListener('click', e => {
if (
e.target.classList.contains('seat') &&
!e.target.classList.contains('occupied')
) {
e.target.classList.toggle('selected');
updateSelectedCount();
}
});
// Initial count and total set
updateSelectedCount();
3. style.css
Let's create a CSS file named style.css and add the following CSS code to it:
@import url('https://fonts.googleapis.com/css?family=Lato&display=swap');
* {
box-sizing: border-box;
}
body {
background-color: #242333;

flex-direction: column;
align-items: center;
justify-content: center;
height: 100vh;
font-family: 'Lato', sans-serif;
margin: 0;
}
.movie-container {
margin: 20px 0;
}
.movie-container select {
background-color: #fff;
border: 0;
border-radius: 5px;
font-size: 14px;
margin-left: 10px;
padding: 5px 15px 5px 15px;
-moz-appearance: none;
-webkit-appearance: none;
appearance: none;
}
.container {
perspective: 1000px;
margin-bottom: 30px;
}
.seat {
background-color: #444451;
height: 12px;
width: 15px;
margin: 3px;
border-top-left-radius: 10px;
border-top-right-radius: 10px;
}
.seat.selected {
background-color: #6feaf6;
}
.seat.occupied {
background-color: #fff;
}
.seat:nth-of-type(2) {
margin-right: 18px;
}
.seat:nth-last-of-type(2) {
margin-left: 18px;
}
.seat:not(.occupied):hover {
cursor: pointer;
transform: scale(1.2);
}
.showcase .seat:not(.occupied):hover {
cursor: default;
transform: scale(1);
}
.showcase {
background: rgba(0, 0, 0, 0.1);
padding: 5px 10px;
border-radius: 5px;
color: #777;
list-style-type: none;
display: flex;
justify-content: space-between;
}
.showcase li {
display: flex;
align-items: center;
justify-content: center;
margin: 0 10px;
}
.showcase li small {
margin-left: 2px;
}
.row {
display: flex;
}
.screen {
background-color: #fff;
height: 70px;
width: 100%;
margin: 15px 0;
transform: rotateX(-45deg);
box-shadow: 0 3px 10px rgba(255, 255, 255, 0.7);
}
p.text {
margin: 5px 0;
}
p.text span {
color: #6feaf6;
}
Open index.html in Browser
Let's open the index.html file in the browser and you will be able to see the following screen:
