Question

我试图为我放在地图上的每个标记添加一个信息窗口。信息窗口仅显示最后添加的标记。我在这里尝试了其他解决方案但没有一个工作。目前我正在使用以下代码执行此操作：

（违规代码在评论中途开始//正在进行中）

function placeMarker(data, map){
var lati, lngi, title, details;
var image = 'image.png';

  for(i=0; i < data.length; i++){
    console.log(data[i].eventLocation + " OF TYPE " + data[i].eventType);
    if(data[i].eventName != ""){
      title = data[i].eventName;
    }
    if(data[i].eventDetails != ""){
      details = data[i].eventDetails;
    }

      if(data[i].eventLocation == "Location 1"){
        lati = -29.651409;
        lngi = 82.342909;
      }
      else if(data[i].eventLocation == "Location 2"){
        lati = -29.637712;
        lngi = 82.368024;
      }
      else if(data[i].eventLocation == "Location 3"){
        lati = -29.650533;
        lngi = 82.342684;
      }
      else{
        lati = -29.645793;
        lngi = 82.347717;
        console.log(data[i].eventLocation + " not found");
      }
      // WORK IN PROGRESS
      var infowindow = new google.maps.InfoWindow({
          content: details
        });

      newMarker = new google.maps.Marker({
        position: {lat: lati, lng: lngi},
        title : title,
        map: map,
        icon: image,
        details: details
      });

      newMarker.addListener('click', function() { //needs some work to connect to each marker instead of last one placed
          infowindow.open(map, newMarker);
        });
  }
}

function initMap(data) {
  var uluru = {lat: -29.643220, lng: 82.350427};
  var map = new google.maps.Map(document.getElementById('map'), {
    zoom: 14,
    center: uluru
  });
 // Marker Images
  var centerMarker = new google.maps.Marker({
    position: {lat: -29.643894, lng: 82.354748},
    map: map,
    icon: image3
  });
  placeMarker(data, map);
}

试图找到解决方案让我显示在每个标记上输入的最后一个信息，但不显示相应标记的正确信息。我改变了这个：

＆＃13;

newMarker.addListener('click', function() { //needs some work to connect to each marker instead of last one placed
          infowindow.open(map, newMarker);
        });

＆＃13;

google.maps.event.addListener(newMarker, 'click', function() { //needs some work to connect to each marker instead of last one placed
          infowindow.open(map, this);
        });

尝试这样放置，在循环之前定义此函数：

var assignListener = function(markerObj, infoWindowObj){
                        return function() {
                               infoWindowObj.open(map, markerObj);
                                };
                      };

然后通过该函数添加侦听器：

 newMarker.addListener('click', assignListener(newMarker, infowindow) );

尝试我的修改..我无法调试你的结束但让我知道这是否有效......如果没有，我想这会帮助你看到我用来迭代循环然后填充的方式空数组，包含所有标记信息，详细信息等，并将该事件附加到地图..

heapq.nsmallest

看看这是否有效..
