Monitoring DOM Events with Chrome DevTools: A Comprehensive Guide

Understanding the behavior of a customizable form element on a web page is crucial for effective event handling. Chrome Developer Tools offers the ability to monitor events fired on an element, providing insights into their occurrences.

Using the monitorEvents Function

To monitor events fired on a specific element:

1. Inspect the desired element using Chrome DevTools.
2. Open the Console tab.
3. Type monitorEvents($0) in the console, where $0 represents the selected element.

As you interact with the element (e.g., move the mouse, click), the fired events' names and data will appear in the console.

Unmonitoring Events

To stop monitoring events, type unmonitorEvents($0) in the console.

Specifying Event Types

You can narrow down the monitored events by specifying a type as the second parameter:

monitorEvents(document.body, 'mouse');

This will only monitor mouse-related events like "mousedown", "mouseup", and "mousemove".

Available Event Types (as of 2023-01-30)

• mouse: "mousedown", "mouseup", "click", "dblclick", "mousemove", "mouseover", "mouseout", "mousewheel"
• key: "keydown", "keyup", "keypress", "textInput"
• touch: "touchstart", "touchmove", "touchend", "touchcancel"
• control: "resize", "scroll", "zoom", "focus", "blur", "select", "change", "submit", "reset"
