我创建了一个谷歌地图，用于从csv文件中检索数据。这似乎工作正常，但是当我遍历所有对象时，infoWindow似乎不起作用。我想这是因为marker变量在for循环中。我已经尝试将代码移动到循环内部，但是这会导致infoWindow随机放置在地图上而不是单击的标记上方。如何实现infoWindow使用多个标记？

答案 0 :(得分：0)
我认为你应该将标记对象存储在一个对象数组中。例如：
var arrayOfMarkers = [];
for (var i = 0; i < data.length; i++) {
// Create a lat/long object readable by Google
var myLatlng = new google.maps.LatLng(parseFloat(data[i][0]), parseFloat(data[i][1]));
// Generate a marker from the lat/long object and add it to the map
var marker = new google.maps.Marker({
position: myLatlng,
map: mapCanvas,
title: data[i][2],
description: data[i][3]
});
arrayOfMarkers.push(marker);
}
然后使用arrayOfMarkers迭代每个Info Windows的事件监听器
[更新 - 用户点击标记后添加地面叠加层]
请在此处查看演示：http://codepen.io/dannypranoto/pen/PNdvzb
您需要做的就是设置一个新功能，用于创建一个参数为imageBound的新地面覆盖
this.instance = new google.maps.Map(document.getElementById('map'), {
center: new google.maps.LatLng(40.740, -74.18),
zoom: 13,
});
this.addGroundOverlay = function(data) {
var instance = this.instance;
var groundOverlay = new google.maps.GroundOverlay(
'http://i.stack.imgur.com/0mgx2.jpg',data);
groundOverlay.setMap(instance);
}
然后调用google.maps.event.addListener(marker, ...)
this.addMarker = function(data) {
var Map = this;
var instance = this.instance;
var content = String.format(this.contentTemplate, data.image_url, data.name, data.summary);
var marker = new google.maps.Marker({
position: new google.maps.LatLng(data.latitude, data.longitude),
title: data.name
});
marker.setMap(instance);
google.maps.event.addListener(marker, 'click', function() {
var imageBound = {
north: 40.773941,
south: 40.712216,
east: -74.12544,
west: -74.22655
}
Map.addGroundOverlay(imageBound);
});
}
