javascript - 使用 2 种方法在 Google map 上显示标记和折线

Question

我正在尝试结合两种不同的方法来在一张 map 上显示标记和折线。是否可以？如果是这样我该怎么做。或者相反，我如何将折线添加到我的标记样本中。

如果没有我的实际代码，我很高兴这可能是一个浪费的帖子..但我在添加我的代码时遇到了麻烦..也许这应该是我的第一个问题..

此脚本将添加标记并在它们之间绘制多段线:

<script>

  var poly;
  var map;

  function initialize() {
    var chicago = new google.maps.LatLng(41.879535, -87.624333);
    var mapOptions = {
      zoom: 7,
      center: chicago,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    };

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

    var polyOptions = {
      strokeColor: '#000000',
      strokeOpacity: 1.0,
      strokeWeight: 3
    }
    poly = new google.maps.Polyline(polyOptions);
    poly.setMap(map);

    // Add a listener for the click event
    google.maps.event.addListener(map, 'click', addLatLng);
  }

  /**
   * Handles click events on a map, and adds a new point to the Polyline.
   * @param {MouseEvent} mouseEvent
   */
  function addLatLng(event) {

    var path = poly.getPath();

    // Because path is an MVCArray, we can simply append a new coordinate
    // and it will automatically appear
    path.push(event.latLng);

    // Add a new marker at the new plotted point on the polyline.
    var marker = new google.maps.Marker({
      position: event.latLng,
      title: '#' + path.getLength(),
      map: map
    });
  }

</script>
