Don't be too dispointed, I may have a solution for your problem. I think you
can have an input field in the form and have your parameter in that field
and the request will send it for you, on the javaside, use
request.getParameter to get it, look like that, at client site:
function assignValue()
{
//do some other job
var changeTo = "value";
document.myform.name.value = changeTo; // do your script logic here
return true;
}
<form method="post" action="..." name="myform" onsubmit="return
assignValue()">
<input type="text" name="name" value="<%=whateverhere%>">
On the java side, you simplely need as you always to with others:
String name = (String)request.getParameter("name");
you can get what ever value you have assigned in your javascript function.
So if your question is how to pass a dynamic value to the server, I guess
the trick is reset the value in your script function right before you submit
the form. Therefore, although you see the value of the form looks "3", but
the value may be well changed to whatever you want when it arrives the
server.
Hope it answer your question

ok, hmm, I see what you are saying, but it's a bit disappoiting. I
really need
a way to
dynamically pass a javascript parameter to the server object. :(
thanks a lot though.
