Hi,

Looking at the dart:js library I can't see any way to bind to js events, in my code at the moment i do this

' _alohaContext.bind('aloha-editable-deactivated', _jsEditableDeactivated);

This binds the aloha-editable-deactivated event to my handling callback in Dart, how would I do this with the dart:js package and/or using it with other supporting packages?

from aloha.

Here's one way that might work, though I haven't tested it:

_alohaContext.callMetho('on', ['aloha-editable-deactivated'], _jsEditableDeactivated);

Maybe @justinfagnani knows of a better way?

from aloha.

Not quite as above, but it does work -
jsnew.JsObject _alohaContextNew = jsnew.context['Aloha'];
_jsReady() {
_ready = true;
_onReady.add(null);

};

_alohaContextNew.callMethod('bind', ['aloha-ready',_jsReady]);

OK I think I'm good to go with the conversion, I'll update Aloha to use dart:js

from aloha.

yep, that looks right!

OK, job done, all converted to use dart:js.

This was well worthwhile, not only have we ended up using the way we are going with js interop I've learned a lot about dart:js on the way.

This was helped by the fact the debugger allows you now to see the js side of the js proxy (JsObject), when I did this originally either the way package:js worked or the the debugger worked didn't allow me to do this, either way its much better now.

@shamblett glad to hear it! If you have a time, a blog post of your experience would be a big help to the community. Or, if you like, you can update this doc with a pull request: https://github.com/dart-lang/www.dartlang.org/tree/master/src/site/articles/js-dart-interop

We can thank @jacob314 for the debugger improvements. :)

@shamblett did you notice any size or speed improvements?
