Question

我已经连接了cordova.js，我有app.initialize();，并且设备准备好了。谁知道为什么？

JS：

var app = {
    initialize: function() {
        this.bindEvents();
    },
    bindEvents: function() {
        document.addEventListener('deviceready', this.onDeviceReady, false);
    },
    onDeviceReady: function() {
        app.receivedEvent('deviceready');
        document.getElementById("finishbutton").addeventlistener("click", greet)
    },
    function greet(){
        alert("The button works.")
    }

};

app.initialize();

HTML：

    </head>
    <body>
        <div 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>
        <button id = "finishbutton">Finish</button>
        <script type="text/javascript" charset="utf-8" src="cordova.js"></script>
        <script type="text/javascript" src="js/index.js"></script>
        <script type="text/javascript">
        app.initialize();
        </script>
    </body>
</html>

如果设备已经启动，我应该可以按下完成按钮并获取警报。相反，它只是锁定“连接到设备”。

试试这个：

  var app = {
        initialize: function() {
            this.bindEvents();
        },
        bindEvents: function() {
            document.addEventListener('deviceready', this.onDeviceReady, false);
        },
        onDeviceReady: function() {
            app.receivedEvent('deviceready');
            document.getElementById("finishbutton").addEventListener("click", this.greet); 
    /*here you were missing the ";" and "Event" and "Listener" should be 
capitalized */
            },
            greet: function(){
              alert("The button works."); /*here you were missing the ";", too. additionally i think you should use greet: function() */
            }

        };

Cordova.js已关联，设备已未启动
