cannot change camera #411

Open juergenroesch opened 2 years ago

juergenroesch commented 2 years ago

I'am using the simple code but on the example-page the change of the camera to backside is available. If I copy the code, I see the "select Camera (2)" but there is no dropdown

To Reproduce

<div id="qr-reader" style="width:100%"></div>
<div id="qr-reader-results"></div>

<script src="https://unpkg.com/html5-qrcode" type="text/javascript"></script>

function onScanSuccess(decodedText, decodedResult) {
    $("#qr-reader-result").text("Code: " + decodedText);
}
var html5QrcodeScanner = new Html5QrcodeScanner(
    "qr-reader", { fps: 10, qrbox: 250 });
html5QrcodeScanner.render(onScanSuccess);

Smartphone (please complete the following information): iPhone different phones

If found the cause... it is related it MaterializeCSS is used, then the select disappears...
