有任何浏览器实现了DOM3 EventListenerList？ [英] Have any browsers implemented the DOM3 EventListenerList?
问题描述
答案不在2010年3月：
The answer was no back in March 2010:
我想知道自那以后是否有任何进展。
I'm wondering if there has been any progress since then.
如果答案仍然没有...任何浏览器可能支持的任何指示？
If the answer's still no ... any indication of when any browser might support it?
推荐答案
EventListenerList在一些旧的草稿的DOM 3事件，并从规范中长期移除。据我所知，至少Gecko仍然没有像常规网页这样的东西，虽然现在有一个用于枚举听众的特权代码（扩展名）的API （请参阅 https://bugzilla.mozilla.org/show_bug.cgi?id=570678#c0 ）。
EventListenerList was in some old draft of DOM 3 Events and was long removed from the spec. As far as I know, at least Gecko still doesn't have anything like this for regular web pages, although it now has an API for privileged code (extensions) to enumerate listeners (see https://bugzilla.mozilla.org/show_bug.cgi?id=570678#c0).
我浏览了W3C邮件列表，有几个关于这个话题的讨论，但显然没有找到任何用例来证明这个特征。这是我可以找到的最新消息：
I looked through the W3C mailing lists, and there were a few discussions on this topic, but apparently no use-cases were found to justify the feature. This is the most recent message I could find:
[...]添加此功能的动机是什么？以前，工作组决定删除相关但不太强大的
hasEventListenerNS方法，因为缺少用例，因为
是潜在的安全问题。
[...] what is the motivation for adding this functionality at all? Previously, the working group resolved to remove the related but less powerful hasEventListenerNS method for lack of a use case, and because there are potential security issues.

(2001) http://lists.w3.org/Archives/Public/w3c-wai-ua/2001OctDec/thread.html#msg89 has some discussion from way back when the EventListenerList was considered.
（2006） http ：//lists.w3.org/Archives/Public/www-archive/2006Mar/0032.html 向作者提出了一个问题，该作者似乎对DOM3 EventListenerList对这种用例的使用情况负责一个特征档案没有列出答复。
(2006) http://lists.w3.org/Archives/Public/www-archive/2006Mar/0032.html asks a question to the author of quirksmode who seems to be responsible for the DOM3 EventListenerList myth about the use cases of such a feature; the archives do not list a reply.
