CustomEvent.initCustomEvent()

这篇翻译不完整。请帮忙从英语翻译这篇文章

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. 如果该时间已经被分发出去,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.

Parameters

type
类型DOMString,事件名称.
canBubble
