js custom event

Comment

// create a custom event
const custom_event = new CustomEvent("custom_event_name", {
	// whether or not the event 'bubbles' up the DOM tree
	// (should parent elements also have their event listener triggered, or just the element itself)
	bubbles: true,
	// special property allowing you to provide additional information
	detail: {
		
	}
});

// to add an event listener
element.addEventListener("custom_event_name", function() {
	// event handler
});

// to trigger an event
element.dispatchEvent(custom_event);
