谷歌地图没有显示地图上的所有目的地标记,只有第一个和最后一个

我有一张谷歌地图,可以正确显示我的路线和所有标记。 https://jsfiddle.net/az5tk8ns/17/

目的地硬编码为: destinations = ["", "durban,KZN", " ixpop,kzn"]

然后,我有另一个函数,它生成我的地址数组:

var addresses = [];
addresses.push('Durban, KZN');
addresses.push('izopo, KZN');`

然后我设置:

destinations = addresses

https://jsfiddle.net/az5tk8ns/19/

进行此操作时,地图仅显示起点和终点标记,而不是我在中间的终点?

如何使用此方法,以便将动态生成的地址数组传递给谷歌地图,并让它显示旅程中的每个点?

完整的谷歌地图语法:

$(document).ready(function() {


var directionsDisplay;
var directionsService = new google.maps.DirectionsService();
var map;
var distancearray=[];
var addresses = [];
addresses.push('Durban, KZN');
addresses.push('izopo, KZN');

warehouse='ladysmith, kwa zulu natal';


function initialize() {
  directionsDisplay = new google.maps.DirectionsRenderer();
  var chicago = new google.maps.LatLng(-28.5710903, 26.0826083);
  var mapOptions = {
    zoom: 7,
    center: chicago
  };
  map = new google.maps.Map(document.getElementById('route_map_canvas'), mapOptions);
  directionsDisplay.setMap(map);
  calcRoute();
}
var origin = "johannesburg",
  destinations = addresses

service = new google.maps.DistanceMatrixService();

function calcRoute() {
  var waypts = [];
  for (var i = 1; i < destinations.length - 1; i++) {
    waypts.push({
      location: destinations[i],
      stopover: true
    });
  }
  var request = {
    origin: origin,
    destination: destinations[destinations.length - 1],
    waypoints: waypts,
    optimizeWaypoints: true,
    travelMode: google.maps.TravelMode.DRIVING
  };
  directionsService.route(request, function(response, status) {
    if (status == google.maps.DirectionsStatus.OK) {
      directionsDisplay.setDirections(response);
      var orig = document.getElementById("orig"),
        dest = document.getElementById("dest"),
        dist = document.getElementById("dist");

      orig.value = response.routes[0].legs[0].start_address;
      dest.value = response.routes[0].legs[0].end_address;
      var total_distance = 0.0;
      for (var i = 0; i < response.routes[0].legs.length; i++) {
        total_distance += response.routes[0].legs[i].distance.value;
        distancearray.push([response.routes[0].legs[i].distance.value]);
        //alert(distancearray);
      }
      dist.value = total_distance + " meters";
    }
  });

}
  initialize();

})

一如既往地感谢,
