event.type property

The event.type property contains the type of an event that occurred.

Syntax

event.type;

In the following example, a click handler is attached to an element, so the event type will be 'click':

<button id="elem">button</button>

let elem = document.querySelector('#elem');

elem.addEventListener('click', function(event) {
	console.log(event.type);
});

The code execution result:

'click'

In the following example, a focus loss handler is bound to an input, so the event type will be 'blur':

<input id="elem">

let elem = document.querySelector('#elem');

elem.addEventListener('blur', function(event) {
	console.log(event.type);
});

The code execution result:

'blur'
