安全上下文
此特征只可用于 安全上下文 (HTTPS)，在某些或所有 支持浏览器 .

Geolocation interface represents an object able to programmatically obtain the position of the device. It gives Web content access to the location of the device. This allows a Web site or app to offer customized results based on the user's location.

An object with this interface is obtained using the navigator.geolocation property implemented by the Navigator 对象。

注意： For security reasons, when a web page tries to access location information, the user is notified and asked to grant permission. Be aware that each browser has its own policies and methods for requesting this permission.

特性

Geolocation interface neither implements, nor inherits any property.

方法

Geolocation interface doesn't inherit any 方法 .

Geolocation.getCurrentPosition() 安全上下文

Determines the device's current location and gives back a GeolocationPosition object with the data.

Geolocation.watchPosition() 安全上下文

返回 long value representing the newly established callback function to be invoked whenever the device location changes.

Geolocation.clearWatch() 安全上下文

Removes the particular handler previously installed using watchPosition() .
