在Google Map api v3中使用交通工具作为我的出行方式

Question

当我在Google Map api V3中使用运输作为我的出行模式时，我在DirectionsRequest中定义了起点、目的地和一些路点。然而，当DirectionsResult回来时，DirectionsLeg只从我的起点开始，以我的目的地结束，它跳过了我所有的航点。我的代码如下所示，这里有没有人遇到同样的问题？

function calcRoute(waypts, mode) {
var sites = [];
var mode;

//Add waypoints to array, the first and last one are not added in waypoints
for (var i = 1; i < waypts.length-2; i++) {
    sites.push({
        location:waypts[i],
        stopover:true}); //Set true to show that stop is required
}

var request = {
    origin: waypts[0], //Set the first one as origin
    destination:waypts[waypts.length-1],//Set the last one as destination
    waypoints:sites,//Set waypoints
    optimizeWaypoints:false,
    travelMode: google.maps.TravelMode[mode]
};

    //Send to Google
directionsService.route(request, function(response, status) {
  if (status == google.maps.DirectionsStatus.OK) {
    directionsDisplay.setDirections(response);
    var route = response.routes[0];
    var HTMLContent = "";

            //Get response and show on my HTML
    for(var i =0; i < route.legs.length; i++){
        HTMLContent = "From " + route.legs[i].start_address + "To " + route.legs[i].end_address + "<br>";
        HTMLContent =  HTMLContent + "Distance:" + route.legs[i].distance.text + "<br>";
    }       
    $("#route_Scroll").append(HTMLContent);
  }else{
      alert(status);
  }
});

}

Answer 1

是啊，https://developers.google.com/maps/documentation/javascript/directions#TransitOptions

“方向请求的可用选项因出行模式而异。请求交通方向时，将忽略avoidHighways、avoidTolls、waypoints[]和optimizeWaypoints选项。您可以通过TransitOptions对象文字指定特定于交通的路由选项。”

如果你想使用它，你必须拆分请求。

Answer 2

当TravelMode正在传输时，您不能指定路点。

the documentation (now) states:

运输方向不支持

路点。

在这种情况下，directions服务总是返回INVALID_REQUEST。
