Question

JavaScript to Applet communication in Firefox

Asked by: jdoggz316

I was wondering if anyone has worked with javascript to java communication in FireFox 2.0? (even 1.5 would be similar i suppose) I'm working with an applet and can get the applet to call javascript functions using JSObject of the liveconnect library. The reverse will not work - i've tried using very dated tags such as applet and invoking public methods of the applet such as

document.applet[0].MethodName();

doesn't work.

 in IE i can invoke methods of the applet through javascript calls such as: dcoument.AppletName.MethodName();

Not in firefox though -

I've tried using object, embed and applet tags in firefox all to no avail.

 has anyone any experiences with invoking java applet methods thru javascript in FireFox?  (or other mozilla browsers?)

Thanks!

>> i can invoke methods of the applet through javascript calls such as: dcoument.AppletName.MethodName

That would work because by AppletName you are specifically getting a handle to that Applet.

Ensure that you have these tags in your OBJECT applet HTML tag:

Internet Explorer:
<param name = "scriptable" value = "true">
<param name = "mayscript" value = "true">

FireFox:
scriptable = "true"
mayscript = "true"

i mistyped - was doing document.applets[0]

firefox 2.0 just seems to do nothing, i dont get an exception, or a js error - i am calling a method in the applet that just returns "Hello World" tried the scriptable="true" in both the object and applet tag.

The method in the applet is :

public static String GetString()
     {
return "Hello World";
     }

if that helps - does someone have source from a working implementation in firefox?
