bootbox 正在停止下拉菜单工作

Question

我有 asp.net 使用引导箱的核心 MVC。我注意到我的下拉菜单不起作用，我尝试了所有方法，例如删除 js 文件和 CSS 文件，然后重新添加它们，但没有成功，直到我删除了 bootbox.js 和 bom！并且下拉菜单工作正常。

这是我的 _Layout.cshtml:

    <meta charset="utf-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>@ViewData["Title"] - POS3</title>

我认为 bootbox.js 中有一些东西只是阻止下拉菜单正常工作。

Answer 1

假设您的项目中的其他所有内容都正确构建，您的布局有很多问题需要修复：

您已经包含 jQuery 好几次了。除一个外，全部删除。
您加载了两个不同版本的 bootstrap.js，并且顺序不对。
您在 <head> 中添加了 bootbox.js 作为第一个脚本。正如我们注意到的在我们的文档中， Bootbox 需要在 Bootstrap 之后加载（因为它是 Bootstrap 扩展）。

因此，删除冗余并修复脚本顺序，这就是您剩下的内容（我在末尾将脚本隔开，以便您可以看到加载的内容）：
