Growl Notifications: How to push Growl notifications from a website?

I'm wondering how I can push desktop Growl notifications from my web application to the user of my web application. I would like to use javascript, if possible, otherwise a language like Ruby or PHP would be my second choice.

Have you implemented something like t开发者_JAVA技巧his before? How can it be done?

I figured out how to use Ruby to push Growl notifications. I would still like to find a JavaScript solution, but if there is no way to use JavaScript, then here is a Ruby solution:

Use the ruby-growl gem:

gem install ruby-growl

Then in your Ruby script:

require 'ruby-growl'
g = Growl.new "localhost", "ruby-growl", ["ruby-growl Notification"]
g.notify "ruby-growl Notification", "It Came From Ruby-Growl", "Greetings!"

Also, in order for this to work, you have to enable "Listen for incoming notifications" and "Allow remote application registration" on the Network tab of the Growl Preference Pane

You can send Growl notifications from Javascript (with a bit of Flash as a helper, but that part is behind the scenes). Here is a test page: http://www.growlforwindows.com/gfw/examples/js/

Note that this only currently works on Windows - the Javascript/Flash support in Growl on the Mac is currently broken as noted here: https://groups.google.com/forum/?fromgroups=#!topic/growl-development/BNF8tcUE1kM
