How can Chrome DevTools help you understand JavaScript events triggered by user interactions?

Monitor Events with Chrome DevTools

In the world of web development, it can be crucial to know which JavaScript events are triggered upon user interactions. Chrome DevTools has a valuable feature that aids in this endeavor: the monitorEvents function.

Using monitorEvents

To leverage this function:

1. Inspect the target element using right-click or the Elements tab.

2. Switch to the Console tab and enter:

   monitorEvents(<pre class="brush:php;toolbar:false">unmonitorEvents(<pre class="brush:php;toolbar:false">monitorEvents(document.body, 'mouse')

   ))

($0 represents the selected DOM element.)

Capturing Event Data

With monitorEvents active, each time you interact with the element, Chrome DevTools will display the event name and its data in the console. This information helps identify the appropriate event handler for your specific needs.
