So, what happened to the DOM level 1?
For example, there are DOM level 0 events like this
window.onload = func;
element.onclick = func;
and there is DOM level 2 (and now even level 3) events
element.addEventListener("click", func, false);
However, there is no mention anywhere about DOM level 1 events? Was it like with Lesuire suit Larry 4 that got lost before it was ever released or was the nr 1 just skipped or didn’t the level 1 include anything related to the events?
DOM Level 0 isn’t an actual spec, DOM Level 0 is just what we call DOM/JS features before the DOM was released. The W3C released DOM Level 1 in 1998. Prior to that there was no DOM spec.
There was no events model in DOM Level 1, it was released in DOM Level 2.
