Question

我正在开发基于原生应用程序的项目。我必须在cordova中编写一个简单的计步器。我已将该插件下载到我的文件中，但我没有成功将所有信息都恢复这是我的代码：

＆＃13;

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 explicitly call 'app.receivedEvent(...);'
    onDeviceReady: function() {
        app.receivedEvent('deviceready');
    },
    // 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);
    }
};

app.initialize();

    // pedometerData.floorsAscended;
    // pedometerData.floorsDescended;
};
         pedometer.startPedometerUpdates(successHandler, onError);
 
         pedometer.stopPedometerUpdates(successCallback, failureCallback);

根据the docs：

平台和设备支持

仅限iOS 8+。甚至，并非所有设备都支持这些功能   使用iOS 8，请确保使用检查功能支持   功能

因此，您可以测试此代码是否支持该功能：

pedometer.isStepCountingAvailable(function(){
    console.log( "Pedometer step counting is available" );
}, function(){
    console.log( "Pedometer step counting is NOT available" );
});

然后您可以使用pedometer.isDistanceAvailable()和pedometer.isFloorCountingAvailable

执行相同的操作

如何使用计步器插件？
