说明：

位置信息将通过手机GPS设备或其它信息如IP地址、移动网络信号获取，由于获取位置信息可能需要较长的时间，当成功获取位置信息后将通过successCB回调函数返回。

参数：

successCB: ( GeolocationSuccessCallback ) 必选 获取设备位置信息成功回调函数
errorCB: ( GeolocationErrorCallback ) 可选 获取设备位置信息失败回调函数
options: ( PositionOptions ) 可选 获取设备位置信息的参数

返回值：

void : 无

属性：

coords: (Coordinates 类型 )地理坐标信息，包括经纬度、海拔、速度等信息
coordsType: (String 类型 )获取到地理坐标信息的坐标系类型
可取以下坐标系类型： "wgs84"：表示WGS-84坐标系； "gcj02"：表示国测局经纬度坐标系； "bd09"：表示百度墨卡托坐标系，仅百度定位支持； "bd09ll"：表示百度经纬度坐标系，仅百度定位支持。
timestamp: (Number 类型 )获取到地理坐标的时间戳信息
时间戳值为从1970年1月1日至今的毫秒数。
address: (Address 类型 )获取到地理位置对应的地址信息
获取地址信息需要连接到服务器进行解析，所以会消耗更多的资源，如果不需要获取地址信息可通过设置PositionOptions参数的geocode属性值为false避免获取地址信息。如果没有获取到地址信息则返回undefined。

平台支持
- Android - 2.3+ (支持) :
  使用系统定位模块无法获取位置信息。
- iOS - 5.1+ (支持) :
  系统定位模块也支持获取位置信息。
addresses: (String 类型 )获取完整地址描述信息
如果没有获取到地址信息则返回undefined。

属性：

latitude: (Number 类型 )坐标纬度值
数据类型对象，地理坐标中的纬度值。
longitude: (Number 类型 )坐标经度值
数据类型对象，地理坐标中的经度值。
altitude: (Number 类型 )海拔信息
数据类型对象，如果无法获取此信息，则此值为空（null）。
accuracy: (Number 类型 )地理坐标信息的精确度信息
数据类型对象，单位为米，其有效值必须大于0。
altitudeAccuracy: (Number 类型 )海拔的精确度信息
数据类型对象，单位为米，其有效值必须大于0。如果无法获取海拔信息，则此值为空（null）。
heading: (Number 类型 )表示设备移动的方向
数据类型对象，范围为0到360，表示相对于正北方向的角度。如果无法获取此信息，则此值为空（null）。如果设备没有移动则此值为NaN。

数据类型对象，单位为米每秒（m/s），其有效值必须大于0。如果无法获取速度信息，则此值为空（null）。

PositionOptions

JSON对象，监听设备位置信息参数

属性：

enableHighAccuracy: (Boolean 类型 )是否高精确度获取位置信息
高精度获取表示需要使用更多的系统资源，默认值为false。
timeout: (Number 类型 )获取位置信息的超时时间
单位为毫秒（ms），默认值为不超时。如果在指定的时间内没有获取到位置信息则触发错误回调函数。
maximumAge: (Number 类型 )获取位置信息的间隔时间
单位为毫秒（ms），默认值为1000（即1秒）。调用plus.geolocation.watchPosition时为更新位置信息的间隔时间。注意：在不同定位模块下支持范围值可能不同，如百度定位模块的间隔范围为大于等于1秒，如果设置的值小于最小值则使用最小值。

provider: (String 类型 )优先使用的定位模块

可取以下供应者： "system"：表示系统定位模块，支持wgs84坐标系； "baidu"：表示百度定位模块，支持gcj02/bd09/bd09ll坐标系； "amap"：表示高德定位模块，支持gcj02坐标系。默认值按以下优先顺序获取（amap>baidu>system），若指定的provider不存在或无效则返回错误回调。注意：百度/高德定位模块需要配置百度/高德地图相关参数才能正常使用。

平台支持

Android - 2.2+ (支持)
iOS - 4.5+ (支持) :
HBuilderX2.4.3+版本支持高德定位模块，默认使用优先级（amap>baidu>system）； HBuilderX2.4.2及以前版本不支持高德定位模块，默认使用系统定位模块。

说明：

这里根据W3C规范定义了定位标准错误码，在此基础上5+ 扩展了错误码，参考 5+ API错误代码中的“Geolocation模块错误”

常量：

PERMISSION_DENIED: (Number 类型 )访问权限被拒绝
系统不允许程序获取定位功能，错误代码常量值为1。
POSITION_UNAVAILABLE: (Number 类型 )位置信息不可用
无法获取有效的位置信息，错误代码常量值为2。
TIMEOUT: (Number 类型 )获取位置信息超时
无法在指定的时间内获取位置信息，错误代码常量值为3。

属性：

code: (Number 类型 )错误代码
可取值：
- PERMISSION_DENIED - 用户拒绝授权
- POSITION_UNAVAILABLE - 位置服务不可用，如系统定位服务关闭
- TIMEOUT - 定位超时，定位时超过PositionOptions.timeout设置的时间触发，此时通常可以重试
- 其它错误 - 5+ 扩展错误码，参考 5+ API错误代码中的“Geolocation模块错误”
message: (String 类型 )错误描述信息
详细错误描述信息。
