Hello
I need to send parameters from Perl to Java function in an ASP page.
I tried something like this:
------------------------------------------------------
<%
$Parameter1 = "Myname";
$Parameter2 = 2;
$Temp->JavaFunc($Parameter1,$Parameter2, 'String');


%>
<script language="JavaScript" >
function JavaFunc(Parameter1, Parameter2, String)
{
}
-----------------------------------------------------
But I got:
" $Temp->JavaFunc($Parameter1,$Parameter2, 'String'); error '80004005'
  Can't call method "JavaFunc" on an undefined value. "

What wrong? or how can I do it else?.
Thanks

You can't pass Perl to JavaScript directly.
Perl is a server side system.
JavaScript is client side.

*IF* you know the layout of your returning HTML pages,
you can get Perl to build a <FORM> containing hidden fields
(<INPUT TYPE=HIDDEN NAME=varname VALUE="valueyouwant">)

Then you can have your Javascript functions do something like
newvalue=document.HIDEFORM.elements[1].value
So your perl needs to output
<FORM NAME=HIDEFORM>
<INPUT TYPE=HIDDEN NAME=Output VALUE="1234">
</FORM>

And newvalue will be set to 1234
(you may have to put elements[0] depending on your browser
version)

You do not have to use forms, as ptruman said.

This will do it:
print <<END;
<SCRIPT LANGUAGE="JavaScript">
<!--
JavaFunc('$Parameter1', '$Parameter2', 'String');
// -->
<SCRIPT>
END
