如果设备没有位置信息, 谷歌浏览器,默认会从谷歌地图访问位置信息.
需要翻墙.

function sucess (e) {
console.log("sucess",e);
}
function fail (e) {
console.log("error",e);
}
window.navigator.geolocation.getCurrentPosition(sucess,fail);
// 开启监听, 当位置发生改变时,会触发. 消耗性能.
var id = window.navigator.geolocation.watchPosition(sucess,fail,options);
// 关闭监听, 需要获取 标识, id
window.navigator.geolocation.clearWatch(id);

var options = {
// 请求时间, 超时会请求失败
timeout : 1000,// 默认infinite
// 是否高精准度
enableHighAccuracy : true,// 默认 false
// 过期时效, 默认 0 有效期无限.
maximumAge : 1000
};

测试移动端 能不能用 地理位置信息
打开 wampserver
用的是猎豹免费wifi 打开了共享,
苹果手机连接上去.
结果失败, 返回的 event.code = 2
返回的 event.message = origin does not have permission to use geolocation service
很懵逼, 百度搜索找到一个# 关于web移动端定位
需要改成 https 协议,wampserver部署https服务器 这尼玛,.
安卓手机也不行.
应该还是需要翻墙.
