javascript - 为什么 onDeviceReady 中的这个与平常不一样？

Question

下面的代码来自PhoneGap 3.0生成的index.js，我的问题是为什么它的设计不允许我们像平常一样使用this.receivedEvent(并获取事件对象作为参数)。

// The scope of 'this' is the event. In order to call the 'receivedEvent'
// function, we must explicity call 'app.receivedEvent(...);'
onDeviceReady: function() {
   app.receivedEvent('deviceready');
},

谢谢

Answer 1

这是通常的调用:

document.addEventListener("deviceready", onDeviceReady, false);

function onDeviceReady() {
    // Now safe to use device APIs
}
