Jquery 引导：切换展开但无法关闭

我不认为我的代码有任何问题，但是当我出于某种原因单击按钮或在切换区域之外时，切换没有关闭。我也试着移动我的头代码，但仍然没有帮助。救命啊！标题部分是我的引导和jquery设置。身体部分是导航栏。先谢谢你

您的问题与您提供给我们的jQuery版本有关：
https://ajax.aspnetcdn.com/ajax/jquery/jquery-2.2.0.min.js
。如果将其更改为
https://ajax.aspnetcdn.com/ajax/jquery/jquery-3.3.1.min.js
您的折叠按钮将起作用。因此，您的标题将是：

<environment include="Development">
    <script src="~/lib/jquery/dist/jquery.js"></script>
    <script src="~/lib/bootstrap/dist/js/bootstrap.js"></script>
    <script src="~/js/site.js" asp-append-version="true"></script>
</environment>
<environment exclude="Development">
    <script src="https://ajax.aspnetcdn.com/ajax/jquery/jquery-3.3.1.min.js"
            asp-fallback-src="~/lib/jquery/dist/jquery.min.js"
            asp-fallback-test="window.jQuery"

折叠按钮仍不工作。我所做的就是把它拿出来，它就起作用了。但是我不知道为什么笑
