boolean true if the default action was prevented. Otherwise, returns false.

preventDefault

The preventDefault() method prevents the default action for a specified event. In this way, the source component suppresses the built-in behavior that follows the event.

stopPropagation

The stopPropagation() method of the Event interface prevents further propagation of the current event in the capturing and bubbling phases.

Example

Set up the event handler of swiperight event.

const listmenu = document.querySelector('smart-list-menu');
listmenu.addEventListener('swiperight', function (event) {
	// event handling code goes here.
})
