if(scannedTextMemo)
{
scannedTextMemo.innerHTML = scannedText;
}
var scannedTextMemoHist =this.scannedTextMemoHistView; /////////////
if(scannedTextMemoHist)
{
scannedTextMemoHist.value = scannedTextMemoHist.value + '\n' + scannedText;
}
}
ngOnInit() {
}
ngAfterViewInit() {
var jbScanner = new JsQRScanner(this.onQRCodeScanned);
jbScanner.setSnapImageMaxSize(300);
