    // 百度地图API功能
    var map = new BMap.Map("allmap");
    map.centerAndZoom(new BMap.Point(112.533643,32.998098), 9);
    
    map.enableScrollWheelZoom();
    madeBoundary();
    

//区域图
    function madeBoundary() {
        
    var datas = new Array("南召县-#665599","方城县-#559955","邓州市-#666ddd","社旗县-#1199cc");
        var bdary = new BMap.Boundary();
        for(var i=0;i<datas.length;i++){
        getBoundary(datas[i],bdary);
            
        } 
        
    } 
//设置区域图

    function getBoundary(data,bdary){    
      data = data.split("-");
        bdary.get(data[0], function(rs){       //获取行政区域
            var count = rs.boundaries.length; //行政区域的点有多少个

              var pointArray = [];
            for (var i = 0; i < count; i++) {
                var ply = new BMap.Polygon(rs.boundaries[i], {strokeWeight: 2, strokeColor: "#ff0000",fillOpacity:0.5,fillColor:data[1]}); //建立多边形覆盖物

            }    
            
    
                            
        });
