what is the difference between js events and DOM events?

Question

I am trying to understand events(such as: click, keyPress...) in js. But when I studied online, I saw it mentioned a lot on 'DOM events'. So my question is js events the same as DOM events? If not, what is the difference?

Answer 1

DOM events fires when the DOM changes or interacts with user, and they are Javascript events. Please have a read all of them: http://www.w3schools.com/jsref/dom_obj_event.asp

Apart from DOM events, you can define your own event objects in Javascript and use the 'dispatchEvent' method to fire that event. For example:

var event = new Event('build');

// Listen for the event.
elem.addEventListener('build', function (e) { ... }, false);

// Dispatch the event.
elem.dispatchEvent(event);

In short, you can think of DOM events are native Javascript events that fires from DOM elements. While a Javascript event can be a DOM event or Custom event
