Hello guys in this tutorial we will create QR Code Generator using HTML CSS & Javascript
First we need to create two files index.html and style.css then we need to do code for it.
Step:1
Add below code inside index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>JavaScript QR Code Generator</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta https-equiv="X-UA-Compatible" content="ie=edge" />
<link rel="stylesheet" href="style.css" />
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">
<script src="https://cdnjs.cloudflare.com/ajax/libs/qrious/4.0.2/qrious.min.js"></script>
</head>
<body>
<div class="QRWrapper">
<div class="QRWrapperInner">
<div class="QRfield">
<input id="qr-text" type="text" placeholder="Text to generate QR code"/>
<button class="qr-btn" onclick="generateQRCode()">Create QR Code</button>
</div>
<div class="qr-code-result">
<p id="qr-result">This is deault QR code:</p>
<canvas id="qr-code"></canvas>
</div>
</div>
</div>
<script>
/* JS comes here */
var qr;
(function() {
qr = new QRious({
element: document.getElementById('qr-code'),
size: 200,
value: 'https://blog.stackfindover.com/'
});
})();
function generateQRCode() {
var qrtext = document.getElementById("qr-text").value;
document.getElementById("qr-result").innerHTML = "QR code for " + qrtext +":";
//alert(qrtext);
qr.set({
foreground: '#0f62fe',
size: 200,
value: qrtext
});
}
</script>
</body>
</html>
Step:2
Then we need to add code for style.css which code i provide in below screen.
* {
padding: 0;
margin: 0;
font-family: 'IBM Plex Sans', sans-serif;
}
.QRWrapper {
display: flex;
align-items: center;
justify-content: center;
height: 100vh;
}
input#qr-text {
font-size: 18px;
padding: 10px 20px;
outline: 0;
border: 1px solid #0f62fe;
min-width: 320px;
}
button.qr-btn {
background-color: #0f62fe;
border: 1px solid transparent;
color: #fff;
cursor: pointer;
padding: calc(.875rem - 3px) 60px calc(.875rem - 3px) 20px;
display: block;
transition: background-color 0.5s;
font-size: 18px;
width: 100%;
text-align: left;
outline: 0;
}
.QRWrapperInner {
display: grid;
row-gap: 50px;
align-items: center;
justify-content: center;
text-align: center;
}
