推荐答案

如果您向下滚动一下，你会看到：

警告！在DOM Level 2
事件中引入了 MutationEvent 接口，但是尚未完全可互操作地在用户代理程序之间实现
。另外，还有一些批评说，
接口的设计引入了一个性能和实现
的挑战。目前正在开发一个新的规范，目的是为了解决突变事件解决的用例，但是以
的表现方式。因此，本规范描述了突变事件
，以供参考和遗留行为的完整性，但不推荐
使用 MutationEvent 接口和 MutationNameEvent
接口。

Warning! The MutationEvent interface was introduced in DOM Level 2 Events, but has not yet been completely and interoperably implemented across user agents. In addition, there have been critiques that the interface, as designed, introduces a performance and implementation challenge. A new specification is under development with the aim of addressing the use cases that mutation events solves, but in more performant manner. Thus, this specification describes mutation events for reference and completeness of legacy behavior, but deprecates the use of both the MutationEvent interface and the MutationNameEvent interface.

替换API是突变观察者，它们完全指定中的.whatwg.org /＃mutation-observersrel =noreferrer>，它们取代了所有的DOM级别X的愚蠢。

The replacement API is mutation observers, which are fully specified in the DOM Living Standard that supercedes all of the DOM level X silliness.
