How to call a Javascript func from an Applet.

[Roberto Gallo]

Hello again;


My objective is to construct a small control structure to coordinate
some applets that are in a single page and need some concurrence control
mechanism and messaging.

I expect to do that using Javascript. I have an applet that needs to
call a Javascript function that is inside the same page the Applet.

How can I do that?





Thank you.

Roberto Gallo.

Why? Why not use another Applet?

The group of people with the relevant
Java, is (slightly) larger than those with
both the relevant Java *and* JS enabled.

[ And, yes, I do know people who
have Java installed, but JS disabled. ]

I didn´t know it was possible. After a google I could find it.
Thank you.

First in the HTML file your applet needs the permission to call JavaScript:
<applet .................. mayscript="true" >

Then in your applet code you can do like this:

import netscape.javascript.*;
....
// first get the window containing your applet:
JSObject window = JSObject.getWindow(this);
// then you can call any javascript stuff:
window.eval("alert('hello')");
...

For more information about the package netscape.javascript (classes
JSObject and JSException) see for example:
http://members.ozemail.com.au/~phoenix1/html/packages.htm
or google for "netscape.javascript.JSObject".
