# QRCode.js
|
||||
QRCode.js is javascript library for making QRCode. QRCode.js supports Cross-browser with HTML5 Canvas and table tag in DOM.
|
||||
QRCode.js has no dependencies.
|
||||
|
||||
## Basic Usages
|
||||
```
|
||||
<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.
|
||||
```
|
||||
|
||||
