从Java Applet调用Javascript函数

Question

I have a Java Applet in a HTML page. I need to have the applet call a certain Javascript function to notify the HTML page of certain events.

The way I call the JavaScript function currently is:

getAppletContext().showDocument(new URL("javascript:window.notifyEvent("+msisdn+")"));

I define the actual function within the HTML code but when the applet actually calls it I get the Uncaught ReferenceError: notifyEvent is not defined error.

Where do I need to define the javascript function for the applet to be able to call it?

Thanks!

Answer 1

To do this, you must use JSObject . It's been around for a long time, although I hear there can be differences between browsers still. So if you need to support many browsers I'd suggest checking across your supported set once you see it work in one.
