## CDN
### jsDelivr

### unpkg
`https://unpkg.com/qrjs2@latest/js/qrjs2.js`
## Usage and Output
## Install
`npm install qrjs2`
### SVG Element (yeah, give it to me)
```js
var div = document.createElement("div"),
text = "https://github.com",
qr = QRCode.generateSVG(text, {
ecclevel: "M",
fillcolor: "#F2F2F2",
textcolor: "#D13438",
margin: 4,
modulesize: 8
});
div.appendChild(qr);
document.body.appendChild(div);
```
Will add an SVG element to parent DIV:
```svg
.bg{fill:#F2F2F2}.fg{fill:#D13438}
...
```
### Data URI SVG String with Data URI PNG String Fallback
```js
var img = document.createElement("img"),
text = "https://github.com";
if (document.implementation.hasFeature("http://www.w3.org/2000/svg","1.1")) {
var qr = QRCode.generateSVG(text, {
ecclevel: "M",
fillcolor: "#E6E6E6",
textcolor: "#486860",
margin: 4,
modulesize: 8
});
var XMLS = new XMLSerializer();
qr = XMLS.serializeToString(qr);
qr = "data:image/svg+xml;base64," + window.btoa(unescape(encodeURIComponent(qr)));
} else {
var qr = QRCode.generatePNG(text, {
ecclevel: "M",
format: "html",
fillcolor: "#CCCCCC",
textcolor: "#006F94",
margin: 4,
modulesize: 8
});
}
img.src = qr;
document.body.appendChild(img);
```
Will add a Data URI SVG string to IMG element's SRC attribute:
```html
![]()
```
Or a Data URI PNG string to IMG element's SRC attribute:
```html
```
### HTML Table Element
```js
var div = document.createElement("div"),
text = "https://github.com",
qr = QRCode.generateHTML(text, {
ecclevel: "M",
fillcolor: "#DCDCDC",
textcolor: "#5C2E91",
margin: 4,
modulesize: 8
});
div.appendChild(qr);
document.body.appendChild(div);
```
Will add an HTML table element to parent DIV:
```html
...
```
