有什么方法可以通过方向服务创建的 wapoint 标记来收听点击功能

Question

基本上，我正在努力实现这件事。 1 - 使用 AJAX 从 MySQL 获取 Lat/long 2 - 使用方向服务和 waypoints 技术在地图上绘制路线。 3 - 当用户点击地图标记时，每个标记都有一个可点击的功能，当点击标记时，位置详细信息将在地图下方的 div 中获取，基本上我需要处理每个标记点击的点击监听器，以便我可以对这些点击执行我想要的操作。

我实现的是：

1 - 能够使用 ajax 请求从 MySQL 使用 PHP REST API.

获取 lat/long

2 - 传递那些标记以使用方向服务映射和绘制路线。思路截图参考https://imgur.com/a/ApkPjTN

1 - 当用户单击时我可以处理方向服务路点生成的每个标记上的单击事件

Answer 1

DirectionsRenderer 有一个 suppressMarkers 属性。用它来删除路线服务自动添加的标记。

然后为您需要的任何点创建您自己的标记（开始 and/or 结束 and/or waypoints）。

下面是一个工作片段，它为每个点创建了一个带有信息窗口的可点击标记。

var map, infowindow, directionDisplay, directionsService;

function initialize() {

  directionsService = new google.maps.DirectionsService();
  infowindow = new google.maps.InfoWindow();

  directionsDisplay = new google.maps.DirectionsRenderer({
    suppressMarkers: true
  });

  var myOptions = {
    zoom: 3,
    mapTypeId: google.maps.MapTypeId.ROADMAP,
  }

  map = new google.maps.Map(document.getElementById("map-canvas"), myOptions);
  directionsDisplay.setMap(map);
  calcRoute();
}

function calcRoute() {

  var waypts = [];

  stop = new google.maps.LatLng(51.943571, 6.463856)
  waypts.push({
    location: stop,
    stopover: true
  });
  stop = new google.maps.LatLng(51.945032, 6.465776)
  waypts.push({
    location: stop,
    stopover: true
  });
  stop = new google.maps.LatLng(51.945538, 6.469413)
  waypts.push({
    location: stop,
    stopover: true
  });
  stop = new google.maps.LatLng(51.947462, 6.467941)
  waypts.push({
    location: stop,
    stopover: true
  });
  stop = new google.maps.LatLng(51.945409, 6.465562)
  waypts.push({
    location: stop,
    stopover: true
  });
  stop = new google.maps.LatLng(51.943700, 6.462096)
  waypts.push({
    location: stop,
    stopover: true
  });

  var start = new google.maps.LatLng(51.943382, 6.463116);
  var end = new google.maps.LatLng(51.946199, 6.461947);

  var request = {
    origin: start,
    destination: end,
    waypoints: waypts,
    optimizeWaypoints: true,
    travelMode: google.maps.DirectionsTravelMode.WALKING
  };

  directionsService.route(request, function(response, status) {
    if (status == google.maps.DirectionsStatus.OK) {

      // Create custom markers for start / end locations
      createMarker(start);
      createMarker(end);

      // Create custom markers for each waypoint
      for (var i = 0; i < waypts.length; i++) {

        createMarker(waypts[i].location);
      }

      directionsDisplay.setDirections(response);
    }
  });
}

function createMarker(latlng) {

  var marker = new google.maps.Marker({
    position: latlng,
    map: map
  });

  google.maps.event.addListener(marker, 'click', function() {

    infowindow.setContent('Clicked marker at ' + this.position.toString());
    infowindow.open(map, this);
  });
}

#map-canvas {
  height: 180px;
}

<div id="map-canvas"></div>
<!-- Replace the value of the key parameter with your own API key. -->
<script async defer src="//maps.googleapis.com/maps/api/js?key=AIzaSyCkUOdZ5y7hMm0yrcCQoCvLwzdM6M8s5qk&callback=initialize">
