bootstrap navbar单页面应用

Question

Bootstrap的导航栏出现问题：https://jsfiddle.net/2wwgt3to/1/ 我正在制作单页面应用程序，事实证明，移动设备的自举下拉导航菜单实际上并不能很好地工作，也就是说，点击后它不会崩溃，我设法通过添加data-toggle="collapse" data-target="#navbar"属性来解决这个问题，但是即使没有下拉表单，整个菜单也会崩溃。从

<div data-toggle="collapse" data-target="#navbar" id="navbar" class="navbar-collapse collapse"> 

编辑的代码

Answer 1

删除数据，拨动= “崩溃” 数据目标= “＃导航栏”：

<nav class="navbar navbar-default navbar-fixed-top"> 
    <div class="container"> 
    <div class="navbar-header"> 
     <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar"> 
     <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="#">Project name</a>
