How can I dynamically set an applet's param values using JavaScript?

Use document.write to generate the APPLET and enclosing PARAM tags. 

<HTML>
    <HEAD>
        <SCRIPT LANGUAGE="JavaScript">

            function writeAppletTag() {
                document.writeln('<APPLET CODE="MyApplet" WIDTH="100" HEIGHT="100">');
                document.writeln(buildParamTag('name1','value1'));
                document.writeln(buildParamTag('name2','value2'));                
                document.writeln('</APPLET>');                
            }

            function buildParamTag(name, value) {
                return '<PARAM NAME="' + name + '" VALUE="' + value + '">';
            }

        </SCRIPT>            
    </HEAD>
    <BODY>    
        <SCRIPT LANGUAGE="JavaScript">
            writeAppletTag();
        </SCRIPT>
    </BODY>
</HTML>

In the example, the parameter names and values are static, but they could for instance be fetched from cookies.

NOTE: Don't bother trying to generate only the PARAM tags (and leave the APPLET tag as regular HTML) because it won't work.
