What content of events does the DOM event module standardize? Why are there events specified by other specifications (such as HTML5)? What is the difference between these normative events? If the event target is not a DOM object, will the event still be propagated based on the event stream? I'm a front-end novice, but I don't have a thorough understanding of this part of the event. I hope the experts can give me some advice...
DOM Standard - 2.1 Introduction to "DOM Events" only defines the event interface and does not specify which events.
Standard events are defined in different DOM levels of W3.
For example, simple and crude Document Object Model Events - Level 2
More elegant Level 3
