Navigator.mozSetMessageHandler()

这篇翻译不完整。请帮忙从英语翻译这篇文章

概要

该方法用来允许应用为系统消息注册处理程序,对消息作出反应。

任何应用都允许注册到任何消息,但一些消息仅仅可以被送到有对应接收权限的应用。不同于DOM事件,如果应用没有针对系统消息的处理程序,它们将留在队列里。如果有排队消息,可以传入一个type参数调用navigator.mozHasPendingMessage()查看,当一个处理程序被设置,待处理消息将异步的地发送到应用。

语法

navigator.mozSetMessageHandler(type, handler);

参数

 
type
type是一个字符串,表示要为其注册处理函数的一类消息。
handler
当系统发送消息时,该处理函数被调用,其接收参数由消息类型来确定。

消息类型

目前Firefox OS允许注册以下消息 :
