如何在Google地图中更改多个图标标记

Question

Sory对于我的英语，我想在谷歌地图中使用多个标记创建路线方向，我在本教程中尝试Direction with multipe marker

现在我要更改图标标记，默认标记为A，B，C，D，就像这个屏幕拍摄

我的问题是如何使用我的图标更改默认图标...尝试使用directionsDisplay.setOptions( { suppressMarkers: true } );图标si not appers ....这是我的代码：

var geocoder;
var map;
var directionsDisplay;
var directionsService = new google.maps.DirectionsService();
var locations = [
  ['Manly Beach', -33.80010128657071, 151.28747820854187, 2],
  ['Bondi Beach', -33.890542, 151.274856, 4],
  ['Coogee Beach', -33.923036, 151.259052, 5],
  ['Maroubra Beach', -33.950198, 151.259302, 1],
  ['Cronulla Beach', -34.028249, 151.157507, 3]
];

function initialize() {
  directionsDisplay = new google.maps.DirectionsRenderer();


  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 10,
    center: new google.maps.LatLng(-33.92, 151.25),
    mapTypeId: google.maps.MapTypeId.ROADMAP
  });
  directionsDisplay.setMap(map);
  directionsDisplay.setOptions( { suppressMarkers: true } );
  var infowindow = new google.maps.InfoWindow();

  var marker, i;
  var request = {
    travelMode: google.maps.TravelMode.DRIVING
  };
  for (i = 0; i < locations.length; i++) {
    marker = new google.maps.Marker({
      position: new google.maps.LatLng(locations[i][1], locations[i][2]),
      icon:'images/dalamkota.png'
    });

    google.maps.event.addListener(marker, 'click', (function(marker, i) {
      return function() {
        infowindow.setContent(locations[i][0]);
        infowindow.open(map, marker);
      }
    })(marker, i));

    if (i == 0) request.origin = marker.getPosition();
    else if (i == locations.length - 1) request.destination = marker.getPosition();
    else {
      if (!request.waypoints) request.waypoints = [];
      request.waypoints.push({
        location: marker.getPosition(),
        stopover: true
      });
    }

  }
  directionsService.route(request, function(result, status) {
    if (status == google.maps.DirectionsStatus.OK) {
      directionsDisplay.setDirections(result);
    }
  });
}
google.maps.event.addDomListener(window, "load", initialize);

我的代码有什么问题...... ???

创建标记时，您缺少map: map部分：

for (i = 0; i < locations.length; i++) {
    marker = new google.maps.Marker({
      position: new google.maps.LatLng(locations[i][1], locations[i][2]),
      icon:'http://s7.postimg.org/wg6bu3jpj/pointer.png',
      map: map
    });
