The hooks added by Google seems more to replace and not to add a
scripting language. My goal is to add a scripting language. Up to now,
i've been able to implement it pretty nicely in the <script> tag by
using either the language or the type attribute. I've got a good part
of the bindings working and can easily interact with the DOM just like
In the events of a tag, i needed to add checks to see what type of
script was being called. A lot if not all of the time, we will usually
defined scripting language and call into the right code. My problem
lies there mostly. At that point, it seems to be "understood" that it
is called that returns a subclass of an EventListener
( JSLazyEventListener ). That's also something i need to change in
order for those functions to return just an EventListener so i can
hook into my own subclass of EventListener. That is where i am right
now, subclassing the EventListener.
The project is challenging but that's the whole point. I think i
understand how i need to do it. I just wanted to ping the list and see
if anyone had any tips or maybe even some sort of document describing
the flow of function calls.
