Question

使用jquery构造进行初始化，getCurrentPosition / watchPosition在iOS Safari或Xcode模拟器上不再起作用。

此代码在5月之前有效。我删除了大多数代码以测试基本的navigator.geolocation.getCurrentPosition功能。如果将getCurrentPosition代码从Historigin对象/初始化函数中拉出并将其放在最后一行之外，则getCurrentPosition将起作用。照原样，我当前得到的结果是：ERROR（3）：位置检索超时。

  function onDeviceReady() {
  Historigin.initialize();
  }
  app.initialize();
  });
</script>
</body>

main.js

var Historigin = {
initialize: function() {

    var options = {
    enableHighAccuracy: true,
    timeout: 5000,
    maximumAge: 0
    };
    function success(pos) {
        var crd = pos.coords;
        console.log('Your current position is:');
        console.log(`Latitude : ${crd.latitude}`);
        console.log(`Longitude: ${crd.longitude}`);
        console.log(`More or less ${crd.accuracy} meters.`);
    }

    function error(err) {
        console.warn(`ERROR(${err.code}): ${err.message}`);
    }

    navigator.geolocation.getCurrentPosition(success, error, options);
}
};

我希望将当前位置的经纬度输出到console.log。

我可以使用app.initialize从jquery构造中执行getCurrentPosition吗
