我在地图上显示标记的信息窗口时遇到了一些麻烦。我有一个json文件，标记返回很好。但是当我点击标记时，信息窗口不会显示。
下面我粘贴所有代码。我感到很困惑，因为我尝试了不同的答案，没有什么工作正常，我花了几天时间来解决这个问题，我需要一些帮助。
在我的代码中，我添加了console.log来测试数据，它在控制台中看起来不错。我会很感激你的每一个建议。

我解决了这个问题。有解决方案：
var infoWin = new google.maps.InfoWindow();
var markers = locations.map(function(location, i) {
var marker = new google.maps.Marker({
position: location,
icon: icon
});
google.maps.event.addListener(marker, 'click', function(evt) {
infoWin.setContent(location.label);
infoWin.open(map, marker);
})
return marker;
});
