Webで現在地取得

Posted at

webで現在地を取得します
こちらの参考サイトよりコードを引用します。

navigator.geolocation.getCurrentPosition(function(position) {
  var latitude = position.coords.latitude;
  var longitude = position.coords.longitude;
  console.log("緯度:" + latitude + ", 経度:" + longitude);
  // 緯度:30.0000000, 経度:130.0000000
});

私の場合は小数点第7位まで測定できました。
緯度と経度から現在地を調べられるサイトを使用しましたが、誤差数メートルです。かなり細い位置まで取得できるんですね。
