Calling JS Functions from an applet..

[SPG]

Hi,

I have a requirement to call a method on a page from an applet that is not
the page that owns the applet..

For example.

Page A has the applet.
It opens page B.

Something happens that makes the applet call a method (Javascript).

I need to be able to call method DoSomething() in Page B from the applet.

I know how to call a method on the main page by using the JSObject returned
from getWindow(this); in the applet.

Is there a way I can pass the reference of the new spawned window into the
applet so I can then call the method on this page?

Cheers,

Steve

If script in page A opens page B make sure you store the window
reference in a global variable:
var win;
win = window.open('pageB.html', 'winB');

then in the applet you should be able to access the variable win as a
member of
JSObject window = getWindow(this);
JSObject win = window.getMember("win");
win.call("functionName", arg)
Of course the usual JavaScript restrictions of same origin policy will
apply so page A and B should come from the same server.

Bingo!
