Question

使用此solution，我可以使用下面的源代码成功映射两个位置。如何在起点和终点位置之间添加第三个或第四个位置作为航点？我试图添加第二个终点，但这不起作用？

我认为，您可以使用Polyline。

尝试此变体：

<!DOCTYPE html>

  <head>
    <meta name="viewport" content="initial-scale=1.0, user-scalable=no">
    <meta charset="utf-8">
    <title>Complex polylines</title>
    <link rel="stylesheet" type="text/css" href="https://developers.google.com/maps/documentation/javascript/examples/default.css">
    <script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false"></script>
    <script>
var poly;
var map;

function initialize() {
  var chicago = new google.maps.LatLng(18.210885,-67.140884);
  var mapOptions = {
    zoom: 20,
    center: chicago,
    mapTypeId: google.maps.MapTypeId.SATELLITE
  };

  map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);

  var lineCoordinates = [
    new google.maps.LatLng(18.210885,-67.140884),
    new google.maps.LatLng(18.211685,-67.141114),
    new google.maps.LatLng(18.211685,-67.141684)
  ];


    var polyOptions = {
      path: lineCoordinates,
      strokeColor: '#dd4b39',
      strokeOpacity: 1.0,
      strokeWeight: 5
    }
    poly = new google.maps.Polyline(polyOptions);
    poly.setMap(map);

    for (i = 0; i <= lineCoordinates.length; i++)
    {
        if (lineCoordinates[i] !== undefined)
        {
            new google.maps.Marker({
              position: lineCoordinates[i],
              title: 'some title',
              map: map
            });
        }
    }
}


google.maps.event.addDomListener(window, 'load', initialize);

    </script>
