我正在进行 Bootstrap 。

<h3>Collapsible Navbar</h3>
<p>In this example, the navigation bar is hidden on small screens and replaced by a button in the top right corner (try to re-size this window).
<p>Only when the button is clicked, the navigation bar will be displayed.</p>

但是在这里，
我希望内容在点击表演时填写“这是表演”，在点击图书馆时填写“这是图书图书馆”。
单击菜单时如何添加操作？
最佳答案
我已将 id 添加到性能和库按钮
<li><a href="#" id="Performance">Performance</a></li>
<li><a href="#" id="Library">Book Library</a></li>
这是一段 javascript 代码
function click(e){
if(e.target.id=="Performance"){
document.getElementsByClassName('container')[0].innerHTML="this is performance";
}
if(e.target.id=="Library"){
document.getElementsByClassName('container')[0].innerHTML="this is library";
}
}
document.getElementById("Performance").addEventListener("click",click,false)
document.getElementById("Library").addEventListener("click",click,false);<body>
<nav class="navbar navbar-inverse">
<div class="container-fluid">

<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar">

<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
