Google 在顶部映射路线多边形

Google maps route polygon on top

接上一个问题

我有很多多边形,它们相互交叉或相互重叠。

我想将当前活动路线放在所有其他路线的顶部,所以多边形的颜色在顶部显示为绿色。

如果您检查下图,则活动多边形位于其他多边形下方。

这将在活动路线上设置颜色变化。

directionsRenderer2.setOptions({
    polylineOptions: {
      strokeColor: 'green'
    },
    map:map
  });

Z-Index

The order in which this polygon is drawn with respect to other overlays, including Polylines, Circles, GroundOverlays and TileOverlays, but not Markers. An overlay with a larger z-index is drawn over overlays with smaller z-indices. The order of overlays with the same z-index value is arbitrary. The default is 0.

所以你可以使用 setZIndex() 来实现,看看 Polygon Public Methods Documentation.

希望对您有所帮助。
