Scripts and Applet

[Roberto Gallo]

Hi;

I have two problems regarding Scripts and Applets. I need to construct a
page that has some instances of the same Applet. These instances are
responsible to get informations from the user and the system. The
information is latter sent to the site.

How can I reference distinct Applets instances of the same Applet Class
inside the page?
How can I get the values stored in the Applet's variables using
JavaScript?

Thank you
Roberto Gallo.

Well, for JavaScript is doesn't matter what class an applet is an
instance of, if you use an <applet> element like
<applet name="applet1" ...>...</applet>
then Javascript can access
var applet = document.applet s.applet1;
Then you can check
if (applet.methodN ame) {
var s = applet.methodNa me();
}
and the applet should have a public method methodName that returns the
value you want from the applet.

Be aware that you have to be sure that the applet is already loaded
before you call any methods. Otherwise you will get a 'applet.methodN ame
is not a function'-error (at least for Mozilla on Linux, at Windows it
works fine for IE and Mozilla).
