leaflet地图遮罩效果图
主要代码： geojson也在下面 地图加载完成之后直接调用 drawBoundaryMask 方法
//边界高亮及遮罩效果
drawBoundaryMask() {
L.geoJSON(this.geojson, {
style: function(feature) {
return {
fillColor: '#000',
stroke: '#CD853F',
fillOpacity: 0.4,
color: '#CD853F',
weight: 2
}
}
}).addTo(this.map)
},
[ [-181, -91], [-181, 91], [181, 91], [181, -90] ],是整个地图的遮罩，中间扣洞的部分是从geojson中直接拿的市的数据。coordinates中第一组数据为整个地图的数据，后面的都是扣洞的数据
