CustomEvent.initCustomEvent()
已废弃: 该特性已经从 Web 标准中删除，虽然一些浏览器目前仍然支持它，但也许会在未来的某个时间停止支持，请尽量不要使用该特性。
CustomEvent.initCustomEvent() 方法初始化了一个 CustomEvent object. 如果该事件已经被分发出去，则不会在初始化过程中重复触发．
这类对象一定是由 Document.createEvent() 方法创建的. 该方法被分发之前必须通过EventTarget.dispatchEvent()方法设置．一旦被分发则，则无法被重新设置．
该方法已经作废，不要在新项目中继续使用该方法.
Instead use specific event constructors, like CustomEvent(). The page on Creating and triggering events gives more information about the way to use these.
Syntax
event.initCustomEvent(type, canBubble, cancelable, detail);
