DOM Level 0事件与DOM Level 2事件之间有什么区别？ [英] What is the difference between DOM Level 0 events vs DOM Level 2 events?

问题描述

DOM Level 0事件与DOM Level 2事件之间有什么区别？我问，因为我被告知Firefox和IE以不同的顺序调用它们，之前我从未听过这些术语。

What is the difference between DOM Level 0 events vs DOM Level 2 events? I ask because I was told that Firefox and IE call them in a different order and I had never heard those terms before.

推荐答案

DOM Level 0事件基于在DOM元素上使用元素属性或命名事件的概念，例如：

DOM Level 0 events were based around the concept of using element attributes or named events on DOM elements, e.g.:

<input type="button" onclick="clickMe();" />

或

input.onclick = function() { ... };

使用DOM Level 2，我们现在有了一种更标准化的方法来管理事件和订阅， addEventListener ， removeEventListener 等。

With DOM Level 2, we've now got a more standardised approach to managing events and subscriptions, with addEventListener, removeEventListener, etc.
