Phonegap Build：加速度计无法正常运行

2019-11-21 11:27:21 作者：互联网

首先,我说我已经看到很多这样的问题,其中许多只是说< script src =“ cordova-x-x-x.js”< / script>有人说不将cordova.js文件包含到Phonegap Build中.

因此,我已经测试和修复了一段时间的代码,仍然从onError函数得到错误信息.我还复制并粘贴了phonegap docs的代码.

因此,这是url中的干净代码：

<!DOCTYPE html>
<html>
  <head>
    <title>Acceleration Example</title>

    <script type="text/javascript" charset="utf-8" src="cordova.js"></script>
    <script type="text/javascript" charset="utf-8">
    document.addEventListener("deviceready", onDeviceReady, false);

    function onDeviceReady() {
        navigator.accelerometer.getCurrentAcceleration(onSuccess, one rror);
    }

    function onSuccess(acceleration) {
        alert('Acceleration X: ' + acceleration.x + '\n' +
              'Acceleration Y: ' + acceleration.y + '\n' +
              'Acceleration Z: ' + acceleration.z + '\n' +
              'Timestamp: '      + acceleration.timestamp + '\n');
    }

    function one rror() {
        alert('onError!');
    }

    </script>
  </head>
  <body>
  </body>
</html>

并且在我的config.xml文件中添加了：

<gap:plugin name="org.apache.cordova.device-motion" />
<gap:plugin name="org.apache.cordova.device-orientation" />

解决方法:

在测试并询问了Phonegap Build的工作人员之后,他们向我展示了具有所有功能的代码.这是使加速度计与Phonegap Build一起使用的最佳方法

    <!DOCTYPE html>
<html>
  <head>
    <title>Device Ready Example</title>

    <script type="text/javascript" charset="utf-8" src="cordova.js"></script>
    <script type="text/javascript" charset="utf-8">

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

    function onDeviceReady() {
        alert("Device is Ready");
        alert(device.available);
    }

    function getAcceleration(){
        navigator.accelerometer.getCurrentAcceleration(onAccelSuccess, one rror);
    }

    function onAccelSuccess(acceleration) {
        var element = document.getElementById('accelerometer');
        element.innerHTML = 'Acceleration X: ' + acceleration.x         + '<br />' +
                            'Acceleration Y: ' + acceleration.y         + '<br />' +
                            'Acceleration Z: ' + acceleration.z         + '<br />' +
                            'Timestamp: '      + acceleration.timestamp + '<br />';
    }

    function one rror() {
        alert('onError!');
    }

    function startWatch() {
        // Update acceleration every 1 seconds
        var options = { frequency: 1000 };

        watchID = navigator.accelerometer.watchAcceleration(onAccelSuccess, one rror, options);
    }

    function stopWatch() {
        if (watchID) {
            navigator.accelerometer.clearWatch(watchID);
            watchID = null;
        }
    }
    </script>
  </head>
  <body onl oad="onLoad()">
    <p>
        <button onclick="getAcceleration()">Get Acceleration</button>
    </p>
    <p>
        <button onclick="startWatch()">Watch Acceleration</button>
    </p>
    <p>
        <button onclick="stopWatch()">Stop Watching Acceleration</button>
    </p>
    <div id="accelerometer">Waiting for accelerometer...</div>
  </body>
</html>
