Phantomjs: getEventListeners

[heiskr]

I use PhantomJS for testing, and for one project we are testing bindings on native DOM objects.

Some of the developer tools include a way to get the event listeners:

https://developer.chrome.com/devtools/docs/commandline-api#geteventlistenersobject
https://getfirebug.com/wiki/index.php/GetEventListeners

It would be neat to have this available in PhantomJS for testing as well.

Love yall!

I love this idea but it poses an interesting question: to what object do we attach the getEventListeners method? It would need to be in the client-side scope of the WebPage instances, so perhaps just to each page's window object?

Coincidentally, this would be very easy to implement by just using JavaScript to duck-punch the addEventListener and removeEventListener methods on the Element prototype as well.

We really need this feature to evaluating web pages for accessibility features

[jongund]

What we really want to test for accessibility is the presence or absence of particular event handlers. For example if their are mouse event handlers on a DOM node or one of its ancestors are their corresponding keyboard event handlers on the DOM node or one of its ancestors.

So initially we would just need a Boolean test to identify any event handlers of a specific type (e.g. mousedown, keypress) on an DOM node.

+1 as this is also related to an IndieUI feature that could/would/will be relevant to other web technologies as well!!
