geolocation.getCurrentPosition

返回設備的當前位置作為 Position 物件。

navigator.geolocation.getCurrentPosition(geolocationSuccess,
                                         [geolocationError],
                                         [geolocationOptions]);

參數

geolocationSuccess：傳遞當前位置的回檔。
geolocationError： *（可選）*如果錯誤發生時執行的回檔。
geolocationOptions： *（可選）*地理定位選項。

說明

geolocation.getCurrentPosition是一個非同步函數。它將返回到該設備的當前位置 geolocationSuccess 回檔與 Position 物件作為參數。如果有錯誤， geolocationError 回檔通過 PositionError 物件。

支援的平臺

Android 系統
黑莓手機 WebWorks （OS 5.0 和更高）
iOS
Tizen
Windows Phone 7 和 8
Windows 8

快速的示例

// onSuccess Callback
// This method accepts a Position object, which contains the
// current GPS coordinates
//
var onSuccess = function(position) {
    alert('Latitude: '          + position.coords.latitude          + '\n' +
          'Longitude: '         + position.coords.longitude         + '\n' +
          'Altitude: '          + position.coords.altitude          + '\n' +
          'Accuracy: '          + position.coords.accuracy          + '\n' +
          'Altitude Accuracy: ' + position.coords.altitudeAccuracy  + '\n' +
          'Heading: '           + position.coords.heading           + '\n' +
          'Speed: '             + position.coords.speed             + '\n' +
          'Timestamp: '         + position.timestamp                + '\n');
};

// onError Callback receives a PositionError object
//
function onError(error) {
    alert('code: '    + error.code    + '\n' +
          'message: ' + error.message + '\n');
}

navigator.geolocation.getCurrentPosition(onSuccess, onError);
