Javascript 正在尝试将引导中的数据切换限制为。单击一次事件

现在，我有一个引导手风琴设置，所以当面板主体被点击时，它会自动关闭该面板并打开下一个面板。我想将此事件限制为每页加载仅发生一次#载体是第一个面板主体#存储器是下一个面板主体的ID

我尝试了一个.one Jquery表达式，但它似乎禁用了accordion。 我猜我需要在JS中这样做，但我希望有一种方法可以在每次页面加载时“数据切换”一次

鉴于您提供的信息，这是我为您提供的一个很好的答案：

这听起来像是一个年轻人的工作

其工作方式是，您有一个变量，比如说

hasacorbianbeenclosed

，然后将其设置为

false

---

在关闭的代码运行之前，添加一个检查，如果这是

true

。运行后，将该变量设置为

true

，它将不会再次运行。

请提供完整的代码示例。很抱歉，刚刚发布了其余部分。请原谅我的无知，我没有人可以问我问题，因为他是指你的JavaScript。（我们都知道Bootstrap的手风琴标记是什么样子的：P）。这听起来正是我所需要的，非常感谢你的帮助。我无法更新你的答案，因为我的代表太低（我相信你知道），我再次标记了答案。我不是在寻找更新的投票，只是希望能有所帮助！很高兴你明白了，伙计！：）
