I recently started a JavaScript course on scrimba. As part of this course I was required to create a passenger counter app. It was relatively easy.
I completed this again locally.
This was my HTML code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Passenger Counter App</title>
<link rel="stylesheet" href="index.css">
<script src="index.js" defer></script>
</head>
<body>
<div class="container">
<h1>People entered:</h1>
<h2 id="count-display">0</h2>
<div class="row">
<a href="#" class="btn" id="increment-btn" onclick="increment()">Increment</a>
<a href="#" class="btn" id="save-btn" onclick="save()">Save</a>
</div>
<p id="entries-log">Previous entries: </p>
</div>
</body>
</html>
This is my CSS styles:
*, *::before, *::after {
box-sizing: border-box;
}
:root {
--primary-dark: #23242b;
--btn-1: #c40000;
--btn-2: #01750b;
}
body {
margin: 0;
min-height: 100vh;
text-align: center;
color: var(--primary-dark);
background-image: url(station.jpg);
background-repeat: no-repeat;
background-size: cover;
font-family: 'Segoe UI', Tahoma, Verdana, sans-serif;
}
h1 {
letter-spacing: 0.125em;
text-transform: capitalize;
}
h2 {
font-size: 4rem;
margin: 0.75em 0;
}
.btn {
color: #FFFFFF;
padding: 0.75em 1.8em;
text-decoration: none;
display: inline-block;
border-radius: 0.25em;
text-transform: uppercase;
font-weight: bold;
letter-spacing: 2px;
}
.btn + .btn {
margin-left: 0.25em;
}
#increment-btn {
background-color: var(--btn-1);
}
#save-btn {
background-color: var(--btn-2);
}
#entries-log {
font-weight: bold;
}
This is my JavaScript Code:
let countDisplay = document.getElementById('count-display');
let entryLog = document.getElementById('entries-log')
let count = 0;
// Increment count being displayed
function increment() {
count++;
countDisplay.textContent = count;
}
// Save and log entries of people entering the station and reinitialize count
function save() {
entryLog.textContent += count + " - ";
count = 0;
}
