Question

我是初学者，很快就遇到了麻烦。首先，我想提一下，我从getbootstrap获得了所有代码，包括复制和粘贴，并根据我的需要进行了调整。首先，我得到了链接和元数据（包括最新的bootstrap 4的链接，alpha版本）。然后我使用了来自getbootstrap的代码snipet，它实现了一个导航栏。我改变了我需要的东西，并使用了我所有的html文档。

现在，它总是在主页上工作，但在其他6页上它很少。我知道这听起来很奇怪，但是，是的，通常导航条在其他页面上根本不会出现，但有时它会在联系页面上出现，例如，稍后它可能会从联系页面再次消失，但在常见问题页面上会出现问题，没有任何人搞乱代码。 mabey它是一个很好的想法，以获得更老但更稳定的bootstrap版本？

这是index.html文件的代码：

    <!DOCTYPE html>

      </button>

      <div class="collapse navbar-collapse" id="navbarSupportedContent">
        <ul class="navbar-nav mr-auto">

    </html>

现在，这是其他一个页面的代码，我认为1就足够了，因为它们是相同的，所以我不会让你无关紧要地阅读7页代码。目前我没有任何css或js文件，因为我使用的是bootstrap。

Answer 1

好的，所以我自己想出来了。

首先，我说我使用了自举版的alpha版本4.我错了，它是测试版。

现在，答案！代码工作正常，这是令人沮丧的根源，因为我一次又一次地查看我知道它是核心的代码，但不知何故它没有工作。它实际上是一个ftp错误，由于某种原因，当我将文件上传到服务器时，其他页面上的导航没有上传，因此浏览器没有显示导航，因为在服务器上有没有导航显示。

bootstrap navbar无法正常工作
