Question

我有一些似乎没有被执行的脚本，但我不知道为什么，我正在尝试使用IOS模拟器和safari来调试它以查看日志。

以下是index.html的内容

<html>
<head>
    <meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *">
    <meta name="format-detection" content="telephone=no">
    <meta name="msapplication-tap-highlight" content="no">
    <meta name="viewport" content="user-scalable=no, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width">
    <link rel="stylesheet" type="text/css" href="css/index.css">
    <title>Test</title>
</head>
<body>

    <div id="appContainer" class="app">
        <h1>Apache Cordova</h1>
        <div id="deviceready" class="blink">
            <p class="event listening">Connecting to Device</p>
            <p class="event received">Device is Ready</p>
        </div>
    </div>
    <script>
      alert('Wait!'); // is not working
    </script>
    <script type="text/javascript" src="cordova.js"></script>
    <script type="text/javascript" src="js/index.js"></script>
</body>

这是index.js的内容

alert("wait"); // That one is working, why ?

var app = {
// Application Constructor
initialize: function() {
    console.log("app init");  // not working
    this.bindEvents();
    console.log("app init end");  // not working
},
// Bind Event Listeners
//
// Bind any events that are required on startup. Common events are:
// "load", "deviceready", "offline", and "online".
bindEvents: function() {
    console.log("bind start");  // not working
    document.addEventListener("deviceready", this.onDeviceReady, false);
    document.addEventListener("click", this.onClick, false);
    console.log("bind end");  // not working
},
// deviceready Event Handler
//
// The scope of "this" is the event. In order to call the "receivedEvent"
// function, we must explicitly call "app.receivedEvent(...);"
onDeviceReady: function() {
    console.log("device start");
    app.receivedEvent("deviceready");
    document.getElementById("appContainer").addEventListener("click", this.onClick, false);
    document.getElementById("appContainer").addEventListener("touchstart", this.onClick, false);
    document.getElementById("appContainer").addEventListener("touchend", this.onClick, false);
    console.log("device end");
},
// 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);
},
onClick: function(e) {
    console.log("click"); // not working or it may be the eventlistener
},

};

console.log("init s"); // not working
app.initialize();
console.log("init e"); // not working

我不明白的是 1 - 为什么index.html中的警报（“等待”）不起作用。 2 - 为什么console.log无法运行设备启动，设备结束和已接收事件：deviceready 3 - 为什么app.initialize似乎没有被执行（因为没有日志）但实际上是因为设备就绪事件被触发而被执行 4 - 当我在模拟器中触发单击时，为什么我看不到onClick函数中的日志（如果设备就绪事件工作，单击，touchstart和touchend应该不工作？）

有人可以向我解释为什么似乎没有什么工作正常吗？

我正在使用cordova 5.3.1，几乎不需要修改init包。我试图删除ios并再次添加它但它没有改变任何东西。

感谢您的帮助

“console”global是一个Apache Cordova插件。它只能 ondeviceready 。看看http://plugins.cordova.io/#/package/org.apache.cordova.console

试试这个

var app = {
    initialize: function() {
        console.log("app init");
        this.bindEvents();
        console.log("app init end");
    },
    // Bind Event Listeners
    bindEvents: function() {
        console.log("bind start");
        document.addEventListener("click", this.onClick, false);
        console.log("bind end"); 
    },
    onDeviceReady: function() {
        console.log("device start");
        app.initialize();
        app.receivedEvent("deviceready");
        document.getElementById("appContainer").addEventListener("click", this.onClick, false);
        document.getElementById("appContainer").addEventListener("touchstart", this.onClick, false);
        document.getElementById("appContainer").addEventListener("touchend", this.onClick, false);
        console.log("device end");
    },
    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);
    },
    onClick: function(e) {
        console.log("click"); // not working or it may be the eventlistener
    },

};

//initialize app on device ready
document.addEventListener("deviceready", app.onDeviceReady, false);

至于你的“警示”之谜，window.alert兼容性在Cordova的背景下已被证明是不可靠的。我建议你使用

navigator.notification.alert

这是插件对话框https://www.npmjs.com/package/cordova-plugin-dialogs

的一部分

另外，如果这是你的目标，有更好的方法来操纵DOM和CSS。
