A highlight from this release

This command returns the event listeners registered on a given object. The object is usually an element, but it can also be e.g. a ‘window’.


The return object can be further inspected in the DOM panel as depicted on the following screenshot.

getEventListeners() command

The screenshot shows an array with two listeners registered for the ‘load’ event. If you click on the f1() or f2() function, you’ll be automatically navigated to the Script panel to see the implementation.

You can try an example online.
