Understanding Events Triggered by Element Interactions

To identify and handle events appropriately on a customizable form element, it's essential to understand the specific events fired upon interaction. Chrome DevTools offers a powerful tool, monitorEvents, to assist in this process.

Using monitorEvents()

1. Inspect the Target Element: Right-click the element and select "Inspect" or locate it in the "Elements" tab of DevTools.
2. Open the Console Tab: Switch to the "Console" tab.
3. Invoke monitorEvents: Type monitorEvents($0) into the console, where $0 represents the selected element.

When you interact with the element (e.g., hovering, clicking), the console will display the event names fired along with their corresponding data.

Stopping Event Monitoring

To cease event monitoring, enter the following command in the console:

unmonitorEvents($0)

Filtering Monitored Events (Optional)

The monitorEvents function allows you to narrow down monitored events by specifying a type as the second parameter. For instance, monitorEvents(document.body, 'mouse') would only log mouse-related events.

Available event types as of 2023-01-30 include:

• mouse
• key
• touch
• control

The monitorEvents feature enables developers to easily observe and troubleshoot event handling for customized form elements, facilitating effective interaction and user experience on the web.
