# jsScannerHandler
Small js script adding barcode/qrcode scanner custom event emulation for websites;

<b>How does it works</b>

Register DOM element which will react to keydown event.
Best option is to use document.

```javascript
new ScannerHandler.register(document);
```

After that add event listener to document element on <b>scanEnd</b> event.

```javascript
document.addEventListener('scanEnd', function(e) {
  document.querySelector("#sth").innerHTML = e.detail.value;
});
```

Value readed by scanner will be in event.detail.value.


Simple wrapper for barcode and qr code readers HID that will fire custom event if input from scanner is detected. Detection at this point is based on time between next input characters.
