Question

我正在尝试获取折线路径中边缘的索引，因为它写在documentation中。但是，每当我在折线上触发click事件时，我都会得到未定义的值。

这是我的代码：edge，path和vertex都是未定义的

route = new google.maps.Polyline({
path: polyLineArray,
strokeColor: "#FF0000",
strokeOpacity: 1.0,
strokeWeight: 5,
clickable: true,
editable: false
});

google.maps.event.addListener(route, 'click', function(evt) {           
  console.log("route click1: " + evt.edge);
  console.log("route click2: " + evt.path);
  console.log("route click2: " + evt.vertex);
  console.log("route click3: " + evt);
  for(var property in evt) {
   console.log("route click4: " + property + " - " + evt[property]);
  }

} }）;

我在这里遗漏了什么吗？非常感谢

我在my test case

上看到相同的结果

进一步测试，看起来它们在“可编辑”折线上可用，如果单击白色方块，则顶点为true，如果编辑折线并单击其中一个“新”顶点，则路径为true ”。 test case with editable polyline

仔细观察documentation，很明显它只适用于可编辑的折线/多边形：

google.maps.PolyMouseEvent object
This object is returned from mouse events on polylines and polygons.

This object extends MouseEvent.
Properties
Properties | Type   | Description
edge       | number | The index of the edge within the path beneath the cursor when 
                    | the event occurred, if the event occurred on a mid-point on an 
                    | editable polygon.
path       | number | The index of the path beneath the cursor when the event 
                    | occurred, if the event occurred on a vertex and the polygon
                    | is editable. Otherwise undefined.
vertex     | number | The index of the vertex beneath the cursor when the event 
                    | occurred, if the event occurred on a vertex and the polyline or 
                    | polygon is editable. If the event does not occur on a vertex, 
                    | the value is undefined.

更多信息。单击小白色方块（“编辑句柄”）给出顶点＃或边数，没有找到一种方法使路径任何东西但未定义，但这可能是因为到目前为止我只使用折线

Google Maps Polyline点击不会触发PolyMouseEvent
