I don't know about the word "fixed" :). But attribute support is definitely one 
of the .NET interop scenarios on my radar.

Subject: Re: [Ironruby-core] ScriptableMember and Silverlight

Hey Sean,

Yeah, I'm well aware of the issue with not being able to use [ScriptableMember] 
for IronRuby. =(

1. Access Javascript variable from Ruby:

If in your HTML you have some variable:
<script type="text/javascript">
  var jsVar = "Hello from Javascript"
</script>

Then in your Ruby script you can access it:

Include System::Windows::Browser
HtmlPage.window.eval "jsVar"

2.  Access Ruby function from Javascript

This is not directly possible because of not having attribute support. Curt 
might have more input into whether this will be fixed in the future.

However, if you're not opposed to hacky solutions, attach Ruby to a JS event 
(HtmlElement#attach_event), and when you want data from Ruby fire the JS event 
and Ruby could write the data to the DOM (a hidden div, perhaps?). Ugh, that 
sucks, but it's what we've got today.

I'd suggest trying the first option, and we'll keep you posted on making Ruby 
objects scriptable from JS.

Hello all,  I need some way to either access a javascript variable or expose a 
function to javascript to be called later.  I've tried option #2, with the 
following call, but I don't know how to specify a member function as 
scriptable.  In C#, you use a meta-flag [ScriptableMember] above the function.

HtmlPage.register_scriptable_object('mn', self)

What about the other approach?  I know you can access the dom, but I need to 
access a plain old variable from javascript.

Thanks!
