Google Maps V3在确切位置重叠标记

标签： javascript php google-maps

我有标记重叠的问题，请不要投票，因为我没有在javascript高度学习也有我看了stackoverflow提供的不同的答案，但还没有能够使用它们找到解决方案所以请帮助！代码是基于我给出的静态点来获取lat和long的php我只想在同一个标​​记中列出所有信息而不是让它重叠标记任何帮助都会受到高度赞赏这里是代码：

如果您不希望标记重叠，则可能需要使用google-maps-utility-library-v3。它有一个名为Marker Clusterer的功能，它基本上允许您将附近的标记放入一个单一标记中。可以对其进行配置，以便一旦用户放大到足够远，这些标记就会再次显示为单独的实体。 Here's an advanced demo

我用这个 - https://github.com/jawj/OverlappingMarkerSpiderfier

在此处查看演示 - http://jawj.github.io/OverlappingMarkerSpiderfier/demo.html

答案 2 :(得分：1)

我通过大量搜索找到了一个解决方案，并且感谢@geocodezip的帖子，当放大标记时我还有一个小问题，任何直接在另一个上的标记将保持在聚集模式，我想实现infoWindow分享两个标记内容任何帮助都会很棒，再次感谢geocodezip你的帖子！

答案 3 :(得分：0)

您可以使用Google地图实用程序库中的MarkerClusterer。

以下是一步一步示例：https://developers.google.com/maps/documentation/javascript/marker-clustering

您可以从google maps github repo下载该库： https://github.com/googlemaps/v3-utility-library/tree/master/markerclusterer

答案 4 :(得分：0)

这是一个不使用任何库的解决方案，而只是简单的javascript作为解决重叠问题的解决方法。

它仅在标记上打开一个信息窗口，该标记在同一个纬度和经度上具有1个以上的标记

var maplocations = [["1200€", "52.50752849999999", "13.471243500000014", "96063", "No", 1],
["12€", "52.50752849999999", "13.471243500000014", "198866", "No", 1],
["12€", "52.504747174113696", "13.420449523925754", "228262", "No", 1],
["888€", "52.5024031", "13.377901000000065", "228317", "No", 1]]

 function initMap() {

        var map = new google.maps.Map(document.getElementById('map'), {
            zoom: 10,
            center: new google.maps.LatLng(52.530339,13.347451),
            mapTypeId: google.maps.MapTypeId.ROADMAP
          });


         groupedMapList=[];
        for(var i=0;i<maplocations.length;i++){
            if(!groupedMapList.find(item => item[1] == maplocations[i][1] && item[2]== maplocations[i][2])){
                groupedMapList.push(maplocations[i])
            }else{
               let valueIndex = groupedMapList.findIndex(item => item[1] == maplocations[i][1] && item[2]== maplocations[i][2]);
               groupedMapList[valueIndex][5] = groupedMapList[valueIndex][5] + 1;
            }
        }

您将获得一个需要在地图上映射的分组列表。仅将信息窗口添加到大于1的项目-“ groupedMapList [i] [5]> 1”

  

var groupedMapList = [[“” 1200€“，” 52.50752849999999“，   “ 13.471243500000014”，“ 96063”，“否”，2]，[“ 12€”，“ 52.504747174113696”，   “ 13.420449523925754”，“ 228262”，“否”，1]，[“ 888€”，“ 52.5024031”，   “ 13.377901000000065”，“ 228317”，“否”，1]] 

        var infowindow = new google.maps.InfoWindow();
        //   var bounds = new google.maps.LatLngBounds();
          var marker, i;
          var prevId;
          var prevMarker;

          for(i=0;i<groupedMapList.length;i++){

                marker = new google.maps.Marker({
                position: new google.maps.LatLng(parseFloat(groupedMapList[i][1]), parseFloat(groupedMapList[i][2])),
                label: {text: groupedMapList[i][0], color: "black"},
                map: map
                });

              google.maps.event.addListener(marker, 'click', (function(marker, i) {
              return function() {
                //reset previous marker

                if(prevMarker)
                {

                    var label = prevMarker.getLabel();
                    label.color="black";
                    prevMarker.setLabel(label); 
                    prevMarker.setZIndex();
                    infowindow.close();
                }

                if(groupedMapList[i][5] > 1){
                    let contentString = '<div id="content">'+ '<b>'+ groupedMapList[i][5] +' Apartments</b></div>'
                    infowindow.setContent(contentString);
                    infowindow.open(map, marker);
                }

                prevId = groupedMapList[i][3];
                prevMarker = this;

                var label = this.getLabel();
                label.color="white";
                this.setLabel(label); 
                this.setZIndex(1001);

              }

            })(marker, i));

        }

    }
