Question

我正在学习如何绘制路线。由于here这个优秀的帖子，这已经完成了。我认为这将是一个简单的过程，在这个例子中添加航路点如下：

   <div style="width: 600px;">
     <div id="map" style="width: 580px; height: 300px; float: left;"></div> 
   </div>

   <script type="text/javascript"> 

     var directionsService = new google.maps.DirectionsService();
     var directionsDisplay = new google.maps.DirectionsRenderer();

     var orig = new google.maps.LatLng(34.011689,-118.49633);
     var dest = new google.maps.LatLng(34.040818,-118.26815);


     //New coordinate defined below
     var wps1 = new google.maps.LatLng(34.069654,-118.44434);

    //Here is the waypoint 
    var waypts = [{ location: wps1, stopover: true }];

     var map = new google.maps.Map(document.getElementById('map'), {
       zoom:7,
       mapTypeId: google.maps.MapTypeId.ROADMAP
     });

     directionsDisplay.setMap(map);


     var request = {
             origin: orig, 
             destination: dest, 
             waypoints: waypts, //Adding the waypoint here 
             travelMode: google.maps.DirectionsTravelMode.DRIVING
     }



      directionsService.route(request, function(response, status) {
       if (status == google.maps.DirectionsStatus.OK) {
         directionsDisplay.setDirections(response);
       }
     });
   </script> 
</body> 
</html>

当我测试这个时，我只看到从海滩到洛杉矶市中心的直接路线。我试图让它首先向绕过加州大学洛杉矶分校。

我已经检查了一些Google documentation，但据我所知。我上面做了什么应该工作？我知道，电脑不会撒谎，但不管它是什么都必须是微妙的。

1。我以正确的格式添加了航点。 2。我告诉处理该航点的请求。

出了什么问题？

Answer 1

这条航点远离洛杉矶：

 var wps1 = new google.mapsLatLng(38.854782,-94.741055);

它有一个拼写错误（地图和LatLng之间缺少一段时间）：

 var wps1 = new google.maps.LatLng(38.854782,-94.741055);

working example

为什么对航点的示例代码的修改失败了？
