利用百度地图进行定位

一、引入地图js

<script type="text/javascript" src="https://api.map.baidu.com/api?v=2.0&ak=bA9nc016nnVW9jeGQgOuSuhWkgpEFdLI"></script>

二、js

/**
 * 定位地区
 * @author xiaohei 2019-05-14

function locateRegion(){
    console.log('定位地区');
    //浏览器定位
    var geolocation = new BMap.Geolocation();  
    geolocation.getCurrentPosition(function(r){
        if(this.getStatus() == BMAP_STATUS_SUCCESS){
            console.log(r);
            //address对象能够获取到详细的地址信息
            var address = r.address;
            var province = address.province;//省
            var city = address.city;//市
            var district = address.district;//区

            var area = province + city + district;
            var currentPosition = area + address.street + address.street_number;//具体地址

            console.log(currentPosition);
            sessionStorage.lng = r.point.lng;//精度
            sessionStorage.lat = r.point.lat; //纬度
        } else {
            alert('failed'+this.getStatus());
        }    
    });
}
