area.forEach((item, index) => {// console.log(item)

data.features.push({
geometry: {coordinates: [item.pointsArr],
type: 'Polygon'
},
properties: {
description: item.description ? item.description : '',
markerLatLng: item.pointsArr[0],
color:color
},
id: index,
type: 'Feature'
})
}) let layer = new PolygonLayer({zIndex: 2})
.source(data)
.color('color',(type)=>{return type})
.shape('fill')
.active(true)
.style({opacity: 0.35})properties 中绑定参数，在办法回调 color 中指定参数名 能够获取到, 多个参数应用 * 拼接 ‘color * description’
