高德地图javascript API开发教(17):高德地图绘制多个多边形

2018年03月06日 09:40 | 5581次浏览

我们利用鼠标工具来实现多边形编辑,引入鼠标工具插件:

 <script src="http://webapi.amap.com/maps?v=1.3&key=您申请的key值&plugin=AMap.PolyEditor"></script>

绘制多边形,如此绘制2个。您也可以绘制多个。

//在地图上绘制折线
    var editor={};
    editor._polygon1=(function(){
        var arr = [ //构建多边形经纬度坐标数组
        [116.403322,39.920255],
        [116.410703,39.897555],
        [116.402292,39.892353],
        [116.389846,39.891365]
        ]
        return new AMap.Polygon({
            map: map,
            path: arr
        });
    })();

绘制完毕,打开多边形可编辑属性。即可编辑多边形。

editor._polygonEditor1= new AMap.PolyEditor(map, editor._polygon1);
editor._polygonEditor1.open();
