getMember() return null
I have some difficulties in applet communicating to javascript.I use IE5 and sun plug-in1.3.
The html file is:
<objectname="sign" classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" mayscript
width = 80 height = 16 codebase="http://java.sun.com/products/plugin/1.3/jinstall-13-win32.cab#Version=1,3,0,0">
<param name = CODE value = "TSignApplet" >
<PARAM NAME = CODEBASE VALUE = "." >
<param name = ARCHIVE value = "TSignApplet.jar" >
<PARAM NAME="MAYSCRIPT" VALUE="true" >
<param name="scriptable" value="true" >
<param name="type" value="application/x-java-applet;version=1.3">

</object>
<form name="theForm" id="theForm">
<input type="button" name="ss" value="sign" onClick="document.sign.hello(document.theForm)">
<input type="text" name="myText" value="demo" >
</form>
The applet method is:
public void hello(JSObject form)
{
try{
if (form==null)
{
System.out.println("the form is null");
}
else
{
System.out.println("form object transfered");
}
System.out.println("object is: "+form.toString());
String name=(String)form.getMember("name");
System.out.println("the form name is:"+name);
JSObject text=(JSObject)form.getMember("myText");
if (text==null)
{
System.out.println("sigh...,the text object is null");
}
}
catch(JSException jse)
{
System.out.println("exception");
}
}
The output is:
form object transfered
object is: sun.plugin.javascript.ocx.JSObject@1671b2
the form name is:null
sigh...,the text object is null
Why does happen?
Thanks in advance.
