微信小程序城市范围画线
- 用的微信小程序原生的map组件多边形polygons 将传入的经纬度连接起来
- 参数：
- points：经纬度数组 array [{latitude: 0, longitude: 0}] 城市边框经纬度
- strokeWidth：描边的宽度 number
- strokeColor：描边的颜色 string 十六进制
- fillColor：填充颜色 string 十六进制 十六进制透明度对照表
- zIndex：设置多边形Z轴数值 number
<map polygons="{{polygon}}" longitude="{{longitude}}" latitude="{{latitude}}"'></map>```
