问题描述
由于一些旧版本的 IE 没有提供事件作为事件监听器的参数，我们习惯了 (event||window.event).
As some old versions of IE didn't provide the event as argument to event listeners, we got used to (event||window.event).
为了确定在现代图书馆中是否仍然有意义，我尝试查看关注的版本，但找不到此信息.
In order to decide whether it can still make some sense to have this in a modern library, I tried to look at what versions were concerned but I couldn't find this information.
那么，没有提供事件作为参数的最新版本的 IE 是什么?
So, what's the most recent version of IE that didn't provide the event as argument ?
推荐答案
Internet Explorer 提供了一个全局对象 window.event，它引用最后一个事件.在 IE9 之前没有参数处理程序.
Internet Explorer provides a global object window.event, which references the last event. And before IE9 there are no arguments in the handler.
