我想在导航栏中单击时事通讯按钮但是模式未显示时尝试启动模态.我跟着其他一些堆栈溢出帖子,并尝试将模态div放在导航栏之外的其他技巧,但似乎没有任何工作.有什么建议？

我的代码的任何其他建议也将不胜感激.谢谢!

刚测试你的模态,它工作正常.唯一可能的原因是您要么没有加载以下文件之一,要么正在加载其中一些文件的过时版本.

因此,请确保您正在加载以下所有文件(按此顺序):

<script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.12.9/umd/popper.min.js" integrity="sha384-ApNbgh9B+Y1QKtv3Rn7W3mgPxhU9K/ScQsAP7hUibX39j7fakFPskvXusvfa0b4Q" crossorigin="anonymous"></script>

并且还要确保您正在加载(在head部分中)最新版本的css,这是:

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0/css/bootstrap.min.css" integrity="sha384-Gn5384xqQ1aoWXA+058RXPxPg6fy4IWvTNh0E263XmFcJlSAwiGgFAW/dAiS6JXm" crossorigin="anonymous">
