javascript中利用地图API实现定位

话不多说，直接上代码

//         百度地图API功能

var geolocation = new BMap.Geolocation();

geolocation.getCurrentPosition(function(r){

    if(this.getStatus() == BMAP_STATUS_SUCCESS){

        var geoc = new BMap.Geocoder();

        var pt = r.point;

        geoc.getLocation(pt, function(rs){

            var addComp = rs.addressComponents;

            // alert(addComp.province + ", " + addComp.city + ", " + addComp.district + ", " + addComp.street + ", " + addComp.streetNumber);

            $city =$(".location");

//                    var city_name = $.fn.cookie('location_city');

            var city_name = Cookies.get('location_city');

 

            if (city_name == addComp.city){

                // TODO 定位城市和cookie值一致, 则不操作

                $city.text(addComp.city);

            } else {

                $city.text(city_name);

                if (confirm('当前位置和定位城市不一致, 是否更改成当前位置?')) {

                    $city.text(addComp.city);

//                            $.fn.cookie('location_city', addComp.city);

//                            Cookies.set('location_city', addComp.city);

                    setLocation();

                }

            }

 

        });

    }

    else {

        alert('定位失败');

    }

 

 

},{enableHighAccuracy: true});

 

function setLocation(){

    var currount_location = $(".location").text();

    Cookies.set('location_city', currount_location);

}
