javascript - markclusterer 覆盖自定义单独的 geoxml3 标记图标

转载作者：行者123 更新时间：2023-12-03 01:41:40

我已经成功地为 geoxml3 解析器自定义了标记图标，但是，引入markerclustererplus 会覆盖自定义的单独图标。我找到了有关更改群集图标的信息，但没有找到有关markerclustererplus 使用的单个图标的信息。

我还失去了单击标记时显示信息窗口(？)的单击功能。我尝试添加一个点击监听器，但它不会产生与 geoxml3 产生的默认行为相同的弹出结果。

(1) 如何自定义markerclustererplus单独图标？编辑:我将图标自定义移动到为markerclusterer数组创建标记的位置，这似乎自定义了单个标记图标，但是，geoxml3解析中存在残留标记，我认为我需要防止在第一个中显示案例？

最佳答案

MarkerClusterer 不会更改标记。您的代码正在使用要添加到 MarkerClusterer 的标记的默认图标。您的 createMarker 函数(来自您的 fiddle ，而不是您的代码片段)不会设置标记的 icon 属性，这意味着它会创建一个具有默认图标的标记:

createMarker:function(placemark){
  var marker = new google.maps.Marker({position:placemark.latlng});
  markerClusterer.addMarker(marker);
},

更正了 createMarker 函数(使用正确的图标):

createMarker: function(placemark) {
  var marker = new google.maps.Marker({
    position: placemark.latlng,
    icon: {
      url: "http://maps.google.com/mapfiles/ms/icons/yellow-dot.png", // url
      scaledSize: new google.maps.Size(48, 48) // scaled size
    }
  });
  markerClusterer.addMarker(marker);
},

proof of concept fiddle

代码片段:

var map;
var myParser;
var markerClusterer;

function initMap() {
  map = new google.maps.Map(document.getElementById('map'), {
    center: {
      lat: 45.4,
      lng: -75.7
    },
    zoom: 14
  });
  var infowindow = new google.maps.InfoWindow();
  markerClusterer = new MarkerClusterer(map, [], {});
  myParser = new geoXML3.parser({
    map: map,
    zoom: false,
    singleInfowindow: true,
    infoWindow: infowindow,
    markerOptions: {
      icon: {
        url: "http://maps.google.com/mapfiles/ms/icons/yellow-dot.png", // url
        scaledSize: new google.maps.Size(48, 48) // scaled size
      }
    },
    createMarker: function(placemark) {
      var marker = myParser.createMarker(placemark);
      markerClusterer.addMarker(marker);
      return marker;
    },
    afterParse: useData
  });
  myParser.parseKmlString(file2kml);

  function useData(docs) {
    console.log("parsed " + docs[0].placemarks.length + " placemarks");
  }
}
google.maps.event.addDomListener(window, 'load', initMap);
