Question

我在phonegap 3.1上有一个罗盘插件的大问题，

这是我的js代码的一部分：

var compass = {
    inicialize:function(){
        var options = {
            frequency: 3000
        };
        var watchID = navigator.compass.watchHeading(compass.showInformation, function(err){console.log('Error',err)},options);
    },

    showInformation:function(heading){
        alert('Heading',heading.magneticHeading);
        console.log('Show Heading',heading);
        $('#compass').html(heading.magneticHeading);
    }
}

我已经在config.xml上添加了插件：

我运行adb logcat，这是我的日志：

Answer 1

这可能是因为没有添加Compass插件。

要添加插件，请在根Cordova项目目录中运行：

cordova plugin add org.apache.cordova.device-orientation

这将通过在您的目录中生成相应的文件来修复有关navigator.compass未定义的错误，但您仍需要添加适当的权限才能使此功能正常工作。

请参阅文档以获取更多详细信息： https://cordova.apache.org/docs/en/3.1.0/cordova_compass_compass.md.html#Compass 建议，每次加载Cordova在线文档，在阅读页面之前，请检查右上角的版本。
