How do I view events fired on an element in Chrome DevTools?

by

I have a customizable form element on a page from a library. I want to see what javascript events are fired when I interact with it because I am trying to find out which event handler to use.

How do I do that using Chrome Web Developer?

You can use monitorEvents function.

Just inspect your element (right mouse click → Inspect on visible element or go to Elements tab in Chrome Developer Tools and select wanted element) then go to Console tab and write:

monitorEvents($0)

Now when you move mouse over this element, focus or click it, the name of the fired event will be displayed with its data.

To stop getting this data just write this to console:

unmonitorEvents($0)

$0 is just the last DOM element selected by Chrome Developer Tools. You can pass any other DOM object there (for example result of getElementById or querySelector).

You can also specify event “type” as second parameter to narrow monitored events to some predefined set. For example:

monitorEvents(document.body, 'mouse')

List of this available types is here.

I made a small gif that illustrates how this feature works:
