Phonegap没有调用设备就绪功能

我无法让设备就绪功能在phonegap即xcode模拟器中工作.html如下:`

    <title>Boilerplate</title>
</head>
<body>

    <div id="main" data-role="page">
        <div data-role="header" class="logo">
            <img class="logo" src="img/premium-logo.jpg" />
        </div>

        <div data-role="content">

            <h1>Apache Cordova Test Zone</h1>
            <div class="test-zone" id="test-zone">

            </div>

        </div>

        <div data-role="footer">

            <h4>Footer of main page</h4>

        </div>

    </div>



    <script type="text/javascript" src="js/jquery-2.0.3.min.js"></script>
    <script type="text/javascript" src="js/jQuery-Mobile-1.3.1-min.js"></script>
    <script type="text/javascript" src="cordova-2.3.0.js"></script>
    <script type="text/javascript" src="js/index.js"></script>
    <script type="text/javascript">
        $(document).ready(init());
    </script>
</body>

Javascript文件index.js:

 function init() {
   document.addEventListener("deviceready", onDeviceReady, false);
 }

 function onDeviceReady() {
   alert('It works!');
 }

如果我注释掉init函数中的行并用onDeviceReady()替换它; 我可以获得关于chrome的警报.

为什么它不能在带有上述代码的模拟器中工作.谢谢

onDeviceReady事件仅在从设备模拟器测试您的phonegap应用程序时有效,而不是在chrome中.

这是我发现做两个框架(phonegap和jQuery Mobile)一起工作的最好方法.

在我的index.html中

 <script type="text/javascript" src="js/libs/LABjs/LAB.min.js"></script>
 <script type="text/javascript" src="js/libs/jQuery/jquery-1.9.1.js"></script>
 <script type="text/javascript" src="js/index.js"></script>
 <script type="text/javascript" src="js/libs/jQuery/jquery.mobile-1.3.1.js"></script>

请注意我使用LABjs库来加载JS脚本(仅当我们检测到我们在设备中时才会加载cordova.js),你可以在google for LABjs库中找到它.

在我的"js/index.js"中

 var deviceReadyDeferred = $.Deferred();
 var jqmReadyDeferred = $.Deferred();
 var resourcesReady = false;


 var app = {
    // Application Constructor
    initialize: function() {
        document.addEventListener('deviceready', this.onDeviceReady, false);

        //load scripts
        if (navigator.userAgent.match(/(iPhone|iPod|iPad|Android|BlackBerry)/)) {
            $LAB.script("cordova.js").wait(
                function(){
                    document.addEventListener('deviceready', this.onDeviceReady, false);
                    console.log('We are on Device');
                }
            );
        }else
        {
            console.log('We are on Browser');
            var _this = this;
            setTimeout(function(){
                _this.onDeviceReady(); 
            }, 1);
        }

        console.log('app.initialize() Called');
        $.when(deviceReadyDeferred, jqmReadyDeferred).then(this.doWhenBothFrameworksReady);
    },

    // deviceready Event Handler
    onDeviceReady: function() {
        console.log("onDeviceReady");
        deviceReadyDeferred.resolve();
    },

    doWhenBothFrameworksReady: function()
    {
        console.log("doWhenBothFrameworksReady");
        resourcesReady = true;
    }
};

$(document).one("mobileinit", function () {
    $.support.cors = true;
    $.mobile.allowCrossDomainPages = true;
    $.mobile.phonegapNavigationEnabled = true;
    console.log('MobileInit');
    jqmReadyDeferred.resolve();
 });



function PageShowFunction(e)
{
    // we are sure that both frameworks are ready here
}

function CallPageEvent(funcToCall,e)
{
    if(resourcesReady)
    {
        return funcToCall(e);
    }else
    {
        setTimeout(function() {
            CallPageEvent(funcToCall,e);
        }, 200);
    }
}


$(document).ready(function () {
    console.log("document ready");
    // ALL the jQuery Mobile page events on pages must be attached here otherwise it will be too late 
    // example:
    // I use the CallPageEvent beacause this event could be called before the device ready
    /* 
     $("#page").on("pageshow", function(e) {
                CallPageEvent(PageShowFunction,e);
            }
     */



});

app.initialize();
