RE: Adding an interface to provide a list of listeners

The enumerating event handler issues are a huge problem for web accessibility evaluation checking tools.

We have to use proprietary APIs to get event handler information for the rules in the OpenAjax Accessibility Evaluation library.

Tools we are developing using proprietary APIs to get event information:

I'm not sure the reply "this been discussed and rejected several times before ... I would advise against reopening the discussion."  is terribly helpful. To Shane's original question: which WG would be best to address this with or to search down the history of the relevant discussions? Is there a way to get access to those previous discussions or at least a summary as to why?

Frankly, it does indeed seem like a worthwhile feature request. A google search for "Get event listener" retrieves over a million results
https://www.google.com/search?q="get+event+listener"

I'm also personally aware of others' desire for something like "getEventListener"
https://www.google.com/search?q=getEventListener


And that search turns up almost a quarter-of-a-million results. The top results are quite relevant to this discussion and also demonstrate that many people are looking for such a thing.  The fact is, the browsers themselves already have this, but it isn't exposed in a way that devs can get to.

The DOM specification is a living standard, so don't worry about
rocking boats.

However, this has been discussed and rejected several times before; is
there any new information that suggests a reasonable chance to
overturn those decisions? If not, I would advise against reopening the
discussion.
