Calling Js From An Applet Works In Firefox & Chrome But Not Safari

I have the following code in an applet to call some Javascript (it's a bit convoluted because the fn that's called gets an object from the DOM identified by divId and calls a funct

Solution 1:

LiveConnect is not fully supported in all browsers. Especially, Safari doesn't convert Java Strings to the prober JS equivalent when using call. In your case you can just use eval at the Applet side instead of call and put in a JSON string object with the arguments. Something like:

javascript.eval(callback + "({\"id\":\"" + id + "\",\" ... })")

Basically, you need to know the cross-browser compatible subset of LiveConnect that works. I've written a blog post that describes the subset: http://blog.aarhusworks.com/applets-missing-information-about-liveconnect-and-deployment/

It comes with a LiveConnect test suite which runs in the browser: http://www.jdams.org/live-connect-test

Solution 2:

I had a similar issue with calling a method on an applet in Safari. It was returning a JavaRuntimeObject that I caused an exception when it was user later on.

As pointed out by @edoloughlin I had to use (applet.getMethod() + "") after which point the proper string was evaluated.

The comment saved me a bunch of time so I thought it useful to add here as I can't comment above.
