谷歌地图API信息窗口

由于这个，您只能看到最后一个元素信息

var marker, i;
for (i = 0; i < data.markers.length; i++) { 
      var image = "/images/markers/green-marker.png";
      marker = new google.maps.Marker({
          position: new google.maps.LatLng(data.markers[i].lat, data.markers[i].lng),
          map: map,
          title: data.markers[i].name,
          icon: image,
      });
      google.maps.event.addListener(marker, "click", function (e) {
          ...
      });
}

您正试图在"for"循环中设置事件侦听器。因此，您的情况与在中为循环传递参数不起作用而创建的Javascript多个动态addEventListener非常相似。

如果你使用这样的东西，这个代码就会起作用：

data.markers.forEach(function(marker){
    var image = "/images/markers/green-marker.png";
    var mapMarker = new google.maps.Marker({
          position: new google.maps.LatLng(marker.lat, marker.lng),
          map: map,
          title: marker.name,
          icon: image,
    });
    google.maps.event.addListener(marker, "click", function(e) {
      ...
    });
    mc.addMaker(mapMarker);
})

问题的重复：Google Maps JS API v3-简单多标记示例

您没有在点击监听器中的i变量上获得函数闭包，并且通过点击监听器内部的循环将始终在数据的最后一个条目处留下信息窗口中的信息：

(function (marker, data) {
    google.maps.event.addListener(marker, "click", function (e) {
        for (i=0; i<data.markers.length; i++) {
            infoWindow.setContent("<div style = 'min-width:200px;min-height:40px'>" + '<img src="' + data.markers[i].link + '" style="height:150px;width:250px;" />' + "<br />" + data.markers[i].description + "<br />" + "<button>Read More</button>" + "</div>");
            infoWindow.open(map, marker);
        }
    });
})(marker, data);

最简单的解决方案是对填充信息窗口所需的数据进行函数闭包，因此您不需要在每次点击标记时迭代整个输入数据集：

(function(marker, data) {
  google.maps.event.addListener(marker, "click", function(e) {
    infoWindow.setContent("<div style = 'min-width:200px;min-height:40px'>" + '<img src="' + data.link + '" style="height:150px;width:250px;" />' + "<br />" + data.description + "<br />" + "<button>Read More</button>" + "</div>");
    infoWindow.open(map, marker);
  });
})(marker, data.markers[i]);
