What Is InitEvents() And Should I Use It In 2018?

I'm trying to understand the code of another programmer and there is a initEvents () method. Some articles tells that this is an outdated method, but I'm not sure. Could you help m

Solution 1:

This is indeed a deprecated method which will init the event before dispatching, you should instead use the Event constructor which have a second argument for event initialisation and then dispatch the event as you like.
Something like this:

// create a look event that bubbles up and cannot be canceled

var evt = new Event("look", {"bubbles":true, "cancelable":false});
document.dispatchEvent(evt);

// event can be dispatched from any element, not only the document
myDiv.dispatchEvent(evt);
