代码语言:javascript复制
    // 百度地图API功能
    var point = null;
    var map = new BMap.Map("l-map");
    map.centerAndZoom(new BMap.Point(116.395645,39.929986), 7);
    map.enableScrollWheelZoom(true);
    //获取浏览器定位
    var geolocation = new BMap.Geolocation();
    geolocation.getCurrentPosition(function(res){
        if(res){
            alert(JSON.stringify(res.point));
            point = res.point;
            analysis(res.point);
            // map.centerAndZoom(new BMap.Point(res.point.lng,res.point.lat),12);
        }
    });
    //解析经纬度
    function analysis(pt){
        var geoc = new BMap.Geocoder();
        geoc.getLocation(new BMap.Point(pt.lng,pt.lat),function(res){
            alert(res.addressComponents.city.substring(0,2));
            map.centerAndZoom(res.address,12);
            geoc.getPoint(res.address, function(pt){
                pt && addMarker(new BMap.Point(pt.lng, pt.lat),new BMap.Label( res.address , {offset:new BMap.Size(20,-10)}));
            }, "中国");
            // map.addOverlay(new BMap.Marker(pt.lng,pt.lat),new BMap.Label(res.address, {offset:new BMap.Size(20,-10)}));
        });
    }
    function addMarker(point,label){// 编写自定义函数,创建标注
        var marker = new BMap.Marker(point);
        map.addOverlay(marker);
        marker.setLabel(label);
        // marker.setAnimation(BMAP_ANIMATION_BOUNCE);//图标动画
    }
