Then, in your Flex application, check for the existance of the jsEnabled variable in Application.application.parameters. If it exists, the <noscript /> block embedded the SWF and the user's JavaScript is disabled. 2) In your Flex app, try calling ExternalInterface.call("Date"). If JavaScript is enabled and ExternalInterface is working, you should get the current date/time from JavaScript. If JavaScript is disabled or ExternalInterface is not available, you should get "null" back. I'll do a bit more testing after work tonight and update the entry. Sorry again for the confusion, Peter OK, I was thinking of this problem over lunch and think I have two possibilities:

I’ll do a bit more testing after work tonight and update the entry.

From the docs: <blockquote>Note: The <code>ExternalInterface.available</code> property reports whether the current container is a type that supports ExternalInterface connectivity. It will not tell you if JavaScript is enabled in the current browser.</blockquote> I'll try and update the entry later today and find a better solution (since as you point out, the Flex Alert is pretty much impossible). :) Peter Klaus,

However, if I do so, I don't get the Flex Alert. Of course I also don't get the Javascript alert, too. Have I got this wrong or is there an issue with the example? Thanks!
