Question

这是我拥有的所有代码，我既没有得到xcode中的日志也没有得到deviceReady事件（我也没有得到任何其他平台。在Ubuntu + Android + Eclipse上我得到了控制台日志，但没有deviceReady。也没有chrome）

js / cordova-1.5.0.js存在并被加载，表示我已放入其中的警告声明。我应该在哪里寻找线索？在此先感谢;）

<div id="d"></div>
<script>
    function foo() {console.log('test'); document.getElementById('d').innerHTML += 'called';}
    window.setTimeout(foo, 5000);
    window.setTimeout(foo, 15000);
    window.setTimeout(foo, 25000);
    window.setTimeout(foo, 35000);
    alert('hi');
    console.log('non timed console.log');

</script>
<script src="js/cordova-1.5.0.js"></script>
<script>    
    document.addEventListener("deviceready", onDeviceReady, false);

    function onDeviceReady() {
        alert('deviceReady');
        //somewhy this never happens
    }

</script>

Answer 1

Console.log仅适用于deviceReady事件
Phonegap为android和ios使用不同的phonegap.js文件，只有 android one随可下载档案一起发布。读 Dhaval的评论，以了解在哪里获得ios版本。
我使用Weinre进行调试，几乎错过了它覆盖了console.log方法，因此console.log不适用于weinre

Answer 2

正如Alex指出的那样，在PhoneGap设备准备好之后，console.log才可用。通过过早调用，您将触发参考错误。

删除所有现有的javascript，然后尝试此操作（使用您自己的自定义代码替换倒数第二行的提醒）：

var app = {
    // denotes whether we are within a mobile device (otherwise we're in a browser)
    iAmPhoneGap: false,
    // how long should we wait for PhoneGap to say the device is ready.
    howPatientAreWe: 10000,
    // id of the 'too_impatient' timeout
    timeoutID: null,
    // id of the 'impatience_remaining' interval reporting.
    impatienceProgressIntervalID: null,

    // 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);
        // after 10 seconds, if we still think we're NOT phonegap, give up.
        app.timeoutID = window.setTimeout(function(appReference) {
            if (!app.iAmPhoneGap) // jeepers, this has taken too long.
                // manually trigger (fudge) the receivedEvent() method.   
                appReference.receivedEvent('too_impatient');
        }, howPatientAreWe, this);
        // keep us updated on the console about how much longer to wait.
        app.impatienceProgressIntervalID = window.setInterval(function areWeThereYet() {
                if (typeof areWeThereYet.howLongLeft == "undefined") { 
                    areWeThereYet.howLongLeft = app.howPatientAreWe; // create a static variable
                } 
                areWeThereYet.howLongLeft -= 1000; // not so much longer to wait.

                console.log("areWeThereYet: Will give PhoneGap another " + areWeThereYet.howLongLeft + "ms");
            }, 1000);
    },
    // 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.iAmPhoneGap = true; // We have a device.
        app.receivedEvent('deviceready');

        // clear the 'too_impatient' timeout .
        window.clearTimeout(app.timeoutID); 
    },
    // Update DOM on a Received Event
    receivedEvent: function(id) {
        // clear the "areWeThereYet" reporting.
        window.clearInterval(app.impatienceProgressIntervalID);
        console.log('Received Event: ' + id);
        myCustomJS(app.iAmPhoneGap); // run my application.
    }
};

app.initialize();

function myCustomJS(trueIfIAmPhoneGap) {
    // put your custom javascript here.
    alert("I am "+ (trueIfIAmPhoneGap?"PhoneGap":"a Browser"));
}

我知道这个问题是在9个月前被问到的，但我偶然发现了同样的问题。

如果您希望调试消息显示在weinre控制台中，则必须调用：

window.cordova.logger.useConsole(false);

在deviceready之后。

<强>更新

您似乎需要运气才能将控制台消息输入weinre - 这很糟糕:(

没有设备准备好，没有使用cordova 1.5的xcode的console.log
