百度地圖只顯示行政區

直接上代碼
百度地圖和高德地圖差不多，也只能到市級，但是高德地圖是使用區域代碼，百度地圖是靠地名定位的區域，所有有可能會出現地名相同在地圖上沒有顯示的這種情況

	// 百度地圖API功能
    var map = new BMap.Map("allmap", { minZoom: 7, maxZoom: 18 });                        // 創建Map實例
    map.centerAndZoom(new BMap.Point(106.524517, 29.546878), 8);     // 初始化地圖,設置中心點座標和地圖級別
    map.enableScrollWheelZoom();

    var cityName = '重慶市';
    var dataArr = [
{
    "name": '九龍坡區',
    "cp": [105.9082, 25.9882]//llabel 顯示的位置
},
{
    "name": "渝中區",
    "cp": [106.6992, 26.7682]
}];
    map.addControl(new BMap.OverviewMapControl());              //添加縮略地圖控件
    map.enableScrollWheelZoom();
    map.addControl(new BMap.NavigationControl({ type: BMAP_NAVIGATION_CONTROL_LARGE ,anchor: BMAP_ANCHOR_TOP_LEFT, offset: new BMap.Size(40, 250)}));
    var bdary = new BMap.Boundary();
    bdary.get(cityName, function (rs) {       //獲取行政區域       
        var EN_JW = "180, 90;";         //東北角
        var NW_JW = "-180,  90;";       //西北角
        var WS_JW = "-180, -90;";       //西南角
        var SE_JW = "180, -90;";        //東南角
        //4.添加環形遮罩層
        var ply1 = new BMap.Polygon(rs.boundaries[0] + SE_JW + SE_JW + WS_JW + NW_JW + EN_JW + SE_JW, { strokeColor: "none", fillColor: "rgb(13,13,40)", fillOpacity: 1, strokeOpacity: 0.5 }); //建立多邊形覆蓋物
        map.addOverlay(ply1);
        getRegion();
    });
    function getRegion() {
        dataArr.forEach(element => {
            var bdary = new BMap.Boundary();
            bdary.get(element['name'], rs => {
                var count = rs.boundaries.length;
                for (let i = 0; i < count; i++) {
                    var ply = new BMap.Polygon(rs.boundaries[i], {
                        strokeWeight: 0.5, strokeColor: '#fff', fillOpacity: 0.6, fillColor: 'rgb(45,67,114)'
                    });
                    this.map.addOverlay(ply);
                }
                citySetLabel(new BMap.Point(element['cp'][0], element['cp'][1]) , element['name']);
            });
        });
    }
   function citySetLabel(cityCenter, cityName) {
        var label = new BMap.Label(cityName, {
            offset: new BMap.Size(-20, -10),
            position: cityCenter
        });
        label.setStyle({
            border: 'none',
            background: 'transparent',
            'font-size': '0.25rem',
            color: '#fff',
        });
        map.addOverlay(label);
    }
