Question

我整天都在修补这一点，似乎无法弄明白。当我渲染地图时，每次单击某个点时，它都会打开添加的最后一个位置的windowInfo。我已经验证了每个xml元素返回它的正确名称，位置，lat / lng等。任何帮助都将不胜感激。

在侦听器中对click事件使用“this”，“marker”仍然包含它在循环中的最后一个值：

google.maps.event.addListener(marker, 'click', function () {
  this.info.open(MYMAP.map, marker);
});

Google Maps API JS所有点在点击时打开相同的infoWindow
