我想希望把几个标记在地图上，这些标记是由“父”标记和“孩子”标记上。所有父标记应同时在地图上可见，而如果点击特定父标记，则应切换开/关特定父标记的子标记我创建了以下工作示例以演示：单张：内创建单独的事件监听for循环

var layergroupParents = L.layerGroup([parent1, parent2]);
layergroupParents.addTo(map);
var child1a = L.marker([50.02, 10.02],{title: 'Child 1a'});

</html>因为我想显示相当多的标志，我想for循环的帮助下把标记的特性为Array（“markerArray”），并处理其标志：

</html>如果执行这些脚本，你会看到，有一些问题，每一个人家长标志分配一个单独的“click”事件。现在，即使我点击第一个父标记，最后父标记的子标记也会打开/关闭。
你知道我该如何解决这些问题，脚本2是否像脚本1一样工作？
