How to find out if there is Javascript code that is listening to keyboard events?

Question

How can I find out if there is Javascript code listening/intercepting keyboard events and ideally find the exact line/location in the code (e.g. in ChromeDev Tools)?

Answer 1

My Answer is for Chrome Browser

• If you need to View event listeners registered on objects then you can use getEventListeners(object)
• If you need to monitor events use monitorEvents()

You can read more about these API

You can also observe these events from the Dev tools
