This topic came up internally on the IE team, and we thought it would
be noteworthy to put this question before the working groups in hopes
of getting a spec clarification made.
The question is: for XHR and other non-DOM related objects that
support the EventTarget interface, meaning objects that will be
surfaced off of "window" but aren't really a part of the markup tree,
how should event propagation be handled?
Events only propagate within a DOM tree. In addition there are some
special cases for the global object noted in the HTML5 specification.
Other than that there is no propagation.
This is I guess a bit unrelated, but I was wondering whether thought
been given to allowing custom events to allow formal propagation beyond
the document (as described in
https://developer.mozilla.org/en/Code_snippets/Interaction_between_privileged_and_non-privileged_pages#Sending_data_from_chrome_to_unprivileged_document
) in a way that works cross-browser?
Although this is more suitable for small-scale experimentation rather
than formal APIs (especially with events not allowing formal
namespaces), it would be nice to have a method for allowing
web<->extension communication that could potentially be expanded to work
in more than one browser, especially as other browsers enhance their
add-on infrastructure. (I guess in Firefox the document is all part of
one big tree that includes the add-on markup, so propagation is indeed
within the same DOM tree, but not sure whether other browsers treat
add-ons as fully separate, or if there is at least interest to make them
work the same way.)
