高德底图 根据行政区域名 加载边界到地图中

Posted 2021-02-09 changgf

function map_map1(place){
//初始化地图对象，加载地图
var map = new AMap.Map("map", {
resizeEnable: true,
center: [117.000923, 36.675807],
zoom: 6
});

var district = null;
var polygons=[];
//加载行政区划插件
if(!district){
//实例化DistrictSearch
var opts = {
subdistrict: 0, //获取边界不需要返回下级行政区
extensions: ‘all‘, //返回行政区边界坐标组等具体信息
level: ‘district‘ //查询行政级别为 市
};

}

district = new AMap.DistrictSearch(opts);
//行政区查询
district.setLevel(‘district‘);
district.search(place, function(status, result) {
map.remove(polygons)//清除上次结果
polygons = [];
var bounds = result.districtList[0].boundaries;
if (bounds) {
for (var i = 0, l = bounds.length; i < l; i++) {
//生成行政区划polygon
var polygon = new AMap.Polygon({
strokeWeight: 1,
path: bounds[i],
fillOpacity: 0.4,
fillColor: ‘#80d8ff‘,
strokeColor: ‘#0091ea‘
});
polygons.push(polygon);
}
}
map.add(polygons)
map.setFitView(polygons);//视口自适应
});
