getEventListeners | object containing all the event listeners | Runtime Evironment library

I would like to gather all events and JavaScript code with dependencies for a particular form field/all form field including frameworks. I have tried with puppeteer and CDP to get the events for a field and subsequently gather JavaScript. I was able to get events details successfully. Not sure how to walk all traces from the event to collect used JavaScript code. Quick help appreciated.

Following code has been used to collect events.

Server part:

I am working on some Puppeteer powered website analytics and would really need to list all events on a page.

It's easy with "normal" JavaScript, so I thought I could just evaluate it in the Puppeteer and get to other tasks.

Well - it is not so easy and "getEventListeners" is not working for example. So this code below is not working (but if I take the code that gets valuated, copy it to browser's console and run - it works well);

When I try to use getEventListeners in puppeteerSharp I got getEventListeners is not defined error:

I'm creating a browser extension to enhance YouTube's keyboard navigation. One of the shortcuts I have in mind is for commenting¹.

_{1: I'm currently using Dart, but it mimics JS and later gets transpiled to it anyway.}

YouTube uses a lot of custom HTML elements, so it hasn't been clear to me what works and when, I end up having to reverse-engineer what's going on every time I'm faced with a custom tag.

I've basically tried mostly something like this:

In Firefox it is possible to see events associated with each element in Inspect Element of developers tools.

I want to have a list of elements and events associated with it, programmatically. preferably using selenium+python.

I know that there is getEventListeners function that can be used in developer tools of Chrome, but it is not accessible in Selenium.

I went through most of the solutions offered in this question, but found nothing to resolve my problem.

My ultimate goal is to iterate throw html elements of a given page and execute each element's events.

So I am making some overrides on a Wordpress plugin. I need to copy the event listener on an element and then replace the element and add it back. The event listener is generated by the plugin.

I thought getEventListeners() would work but I have read that it only works in console. If that is this case I'm really astounded. We're in freaking 2020 and I am not finding an obvious solution to this.

What is the solution here people?

Below is the code I was trying to implement having assumed getEventListeners wasn't just a console function.
