Question

我正在使用phonegap 3而我无法调用我的功能，它无法正常工作！

这是我的代码，它是创建联系人的基本示例，但我不会创建一堆按钮来执行不同的操作，如创建，删除列表和类似的东西，但我无法接受它。执行的唯一代码位于“OnDeviceReady”函数的内部。

我如何调用我的函数以及如何调用？因为基本的Javascript不会运行。谢谢！

我的js文件

var app = {
    // Application Constructor
    initialize: function() {
        this.bindEvents();
    },
    // Bind Event Listeners
    //
    // Bind any events that are required on startup. Common events are:
    // 'load', 'deviceready', 'offline', and 'online'.
    bindEvents: function() {
        document.addEventListener('deviceready', this.onDeviceReady, false);
    },
    // deviceready Event Handler
    //
    // 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');
        var myContact = navigator.contacts.create({"displayName": "Test User"});
        myContact.note = "This contact has a note.";
        console.log("The contact, " + myContact.displayName + ", note: " + myContact.note);
        app.receivedEvent('contactcreated');
        myContact.save(app.onContactSaveSuccess,app.onContactSaveError);
    },
    // Update DOM on a Received Event
    receivedEvent: function(id) {
        var parentElement = document.getElementById(id);
        var listeningElement = parentElement.querySelector('.listening');
        var receivedElement = parentElement.querySelector('.received');
        listeningElement.setAttribute('style', 'display:none;');
        receivedElement.setAttribute('style', 'display:block;');

        console.log('Received Event: ' + id);
    },
    onContactSaveSuccess: function(contact) {
        window.alert("Save Success");
    },
    onContactSaveError: function(contact) {
        window.alert("Save Failed");
    },
};

Seens就像你需要在POO上阅读：http://en.wikipedia.org/wiki/Prototype-based_programming

基本上，您在var app范围内创建的函数如下所示：app.myFunction（）;

如果您希望在发生设备事件时调用，则需要将其添加为设备事件的侦听器。请查看文档：{{3}}
