QRCode.js is a JavaScript library designed for generating QR codes efficiently. It also has wide cross-broswer compatibility. Notably, QRCode.js operates independently, devoid of any external dependencies
<div id="qrcode"></div>
<script type="text/javascript">
new QRCode(document.getElementById("qrcode"), "http://jindo.dev.naver.com/collie");
</script>
or with some options
<div id="qrcode"></div>
<script type="text/javascript">
var qrcode = new QRCode(document.getElementById("qrcode"), {
text: "http://jindo.dev.naver.com/collie",
width: 128,
height: 128,
colorDark : "#000000",
colorLight : "#ffffff",
correctLevel : QRCode.CorrectLevel.H
});
</script>
and you can use some methods
qrcode.clear(); // clear the code.
qrcode.makeCode("http://naver.com"); // make another code.
IE6~10, Chrome, Firefox, Safari, Opera, Mobile Safari, Android, Windows Mobile, ETC.
