[Feature Request] Auto-redirect

[mwambajoshua]

Hey, pardon me for the the dumb question. I there a way to make the scanner automatically redirect once it has decoded the qr url?

Interesting feature request, I would like to prototype this and get back to you.

Thanks for raising this.

for now, you can do this

function validURL(str) {
  var pattern = new RegExp('^(https?:\\/\\/)?'+ // protocol
    '((([a-z\\d]([a-z\\d-]*[a-z\\d])*)\\.)+[a-z]{2,}|'+ // domain name
    '((\\d{1,3}\\.){3}\\d{1,3}))'+ // OR ip (v4) address
    '(\\:\\d+)?(\\/[-a-z\\d%_.~+]*)*'+ // port and path
    '(\\?[;&a-z\\d%_.~+=-]*)?'+ // query string
    '(\\#[-a-z\\d_]*)?$','i'); // fragment locator
  return !!pattern.test(str);
}

function onScanSuccess(qrCodeMessage) {
  if (validURL(qrCodeMessage)) {
    window.location.href = qrCodeMessage;
  }
}

var html5QrcodeScanner = new Html5QrcodeScanner(
	"qr-reader", { fps: 10, qrbox: 250 });
html5QrcodeScanner.render(onScanSuccess);
