Benuterabfrage per Scipt in HTML einbinden

[Pragma]

Nachtrag:

document.write('<OBJECT ID="webcam"...');
...
document.write('<PARAM NAME="Username" VALUE="' + jsVarUser + '">');
document.write('<PARAM NAME="Password" VALUE="' + jsVarPass + '">');

Die Ausgabe von der Username und Password Params per JS sollte reichen:
<OBJECT ...>
<PARAM NAME="Type" VALUE="2">
...
<PARAM NAME="ShowFps" VALUE="1">
<script type="text/javascript">
document.write('<PARAM NAME="Username" VALUE="' + jsVarUser + '">');
document.write('<PARAM NAME="Password" VALUE="' + jsVarPass + '">');
</script>
</OBJECT>
