//isPointInRing为true 当前坐标则在当前多边形区域内let isPointInRing = AMap.GeometryUtil.isPointInRing(point,polygonArr);
通过contains()方法,判断一个点是否在一个区域内
let lnglat = new AMap.LngLat(116.39,39.9);let circle = new AMap.Circle({center: new AMap.LngLat(116.39,39.6),radius: 200, //半径zIndex: 50,})let isContain = circle.contains(lnglat);if(isContain){alert("在圆内")}else{alert("不在圆内")}
