Bootstrap 3响应Naviagion按钮不打开(Bootstrap 3 Responsive Naviagion Button not Opening)

我使用Bootstrap 3来创建响应式导航，但是当我处于响应模式时，它不会在单击按钮时打开它。我不确定是什么导致了这个问题。这对我来说是新的，因为直到现在我还没有发生过这种情况。

<nav class="navbar navbar-default nav-fixed-top"> <div class="container-fluid"> <div class="navbar-header"> <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar"> <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <a class="navbar-brand" href="home.html">Web Page</a> </div> <div class="collapse navbar-collapse" id="myNavbar"> <ul class="nav navbar-nav"> <li><a href="#">Home</a></li> <li><a href="#">Page 2</a></li> <li><a href="#">Page 3</a></li> </ul> </div> </div> </nav>

I'm using Bootstrap 3 to create a responsive navigation, but when I in responsive mode it doesn't open it when clicking the button. I'm not sure what is causing this problem. This is new to me, since I haven't had this happen to me before till now.

最满意答案

包含js和css文件后，它应该可以工作。完整的代码。

<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8">  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> </head> <body> <nav class="navbar navbar-default nav-fixed-top"> <div class="container-fluid"> <div class="navbar-header"> <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar"> <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <a class="navbar-brand" href="home.html">Web Page</a> </div> <div class="collapse navbar-collapse" id="myNavbar"> <ul class="nav navbar-nav"> <li><a href="#">Home</a></li> <li><a href="#">Page 2</a></li> <li><a href="#">Page 3</a></li> </ul> </div> </div> </nav> </body> </html>

After including js and css files it should work. The full code.

<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8">  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script> </head> <body> <nav class="navbar navbar-default nav-fixed-top"> <div class="container-fluid"> <div class="navbar-header"> <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar"> <span class="sr-only">Toggle navigation</span> <span class="icon-bar"></span> <span class="icon-bar"></span> <span class="icon-bar"></span> </button> <a class="navbar-brand" href="home.html">Web Page</a> </div> <div class="collapse navbar-collapse" id="myNavbar"> <ul class="nav navbar-nav"> <li><a href="#">Home</a></li> <li><a href="#">Page 2</a></li> <li><a href="#">Page 3</a></li> </ul> </div> </div> </nav> </body> </html>
