It is possible to call into a plugin using Javascript. You need to
create a mechanism to do this as part of your plugin. This is how the
jnext plugin works. See the web-browsers Foundry27 project home page
news item:

  "Javascript Native Extensions ported to QNX
  Do you want to invoke any local executable or interface to any native
functionality using 
  Javascript on your WebPage? Then the Javascript Native Extensions
framework is what you need. 
  The work done by http://www.jnext.org has been ported to QNX. The
source code is available 
  here:
http://community.qnx.com/svn/repos/web-browsers/3rdparty/trunk/jnext-1.0
.8.3  "

Jnext is just an NPAPI based plugin with Javascript glue at the front
end. You could look into the source code and use some of the same ideas
in your plugin.

Hi,

thank you for you fast answer.
I had a look on the sample-plugin and it looks to me very similar like
the PlugIn I have made for Firefox (np_entry, npn_gate... are the same).
But I have still one question is it not posible to call PluginFunctions
via JavaScript. I "think" NetscapeAPI has the interface to call via
JavaScript functions from Plugin. 
Example:
<object id="simpleplugin" type="application/simple-plugin"
class=hiddenObject></object><br>

<script>
var embedPlug = document.getElementById('simpleplugin');

function show(arg)
{
  document.getElementById("result").innerHTML += "<p>" +  arg + "</p>";
}

if (embedPlug)
{	  
  show("plug.version = " + embedPlug.version); <!--version is a func in
Plugin-->
}


Of course needs the Plugin to include the Java interface.
But maybe I am mixing this with extensions.

If I interpret you answer and the code of Webkit it means to me that it
is not posible to call functions via JavaScript form a Plugin
"Scriptable Plugin". Is it realy only posible to talk between Webkit and
Plugin with defined Functions in the NAPI like Mouseover, Mouseclik,
Loadurl.

Thank You!
