我使用的是phonegap 3，但无法调用我的函数，它不起作用!
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，例如创建、删除列表等类似的操作，但我无法使用它。唯一执行的代码位于“OnDeviceReady”函数内部。
我如何调用我的函数以及如何调用？因为基本的Javascript无法运行。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");
},
};
最佳答案
看来您需要阅读一些有关 POO 的内容:http://en.wikipedia.org/wiki/Prototype-based_programming
基本上，您在 var app 作用域内创建的函数如下所示:app.myFunction();
如果您希望在设备事件发生时调用 then，则需要将 then 添加为设备事件的监听器。看看文档:http://docs.phonegap.com/en/3.4.0/cordova_events_events.md.html#Events
