小程序组件map polygons地块颜色透明度

1.颜色值16进制,后两位数字,为不透明度,如下"#FFCC4080"的#FFCC40+80,80:不透明度为0.8

          let strokeColor = target ? "#FFDD00" : "#FFCC4080";
          let fillColor = target ? "#FFDD0080" : "#FFCC4040";
          let strokeWidth = target ? 4 : 3;
          // console.log(arr[0])
          objA = {
            points: arr,
            fillColor: fillColor,
            strokeColor: strokeColor,
            strokeWidth: strokeWidth,
            zIndex: 1
          }
