我有以下代码,其中包含一些嵌套的div。
div有加号和减号字体的很棒的图标来扩展和折叠它们。
您可以使用页面顶部的按钮切换div的可见性。
蓝色按钮和/或加减图标可以切换父对象的可见性(
Activities
和
Animals & Nature
)。
绿色按钮切换包含子标题的“子”div的可见性,如
award-medal
,则,
event
等
我的问题是,当涉及到用绿色加号/减号图标切换子div的可见性时,如果您单击绿色减号
颁发奖章
航向,它还折叠div
事件
。
我想知道是否有任何方法可以拆分折叠功能,以便绿色切换按钮仍能像现在一样工作,但每个绿色加号/减号图标可以控制图标相关的每个div的可见性。
我可以理解为什么代码现在这样工作,但我无法理解如何更改JS代码才能实现我的目标。
