Bootstrap 导航元素本章我们将讲解 Bootstrap 提供的用于定义导航元素的一些选项。它们使用相同的标记和基类 .nav。Bootstrap 也提供了一个用于共享标记和状态的帮助器类。改变修饰的 class,可以在不同的样式间进行切换。 表格导航或标签创建一个标签式的导航菜单: 下面的实例演示了这点: <!DOCTYPE html><html><head>
<title>Bootstrap 实例 - 标签式的导航菜单</title>
<link href="//cdn.bootcss.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="stylesheet">
<script src="//cdn.bootcss.com/jquery/2.1.1/jquery.min.js" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></script>
<script src="//cdn.bootcss.com/bootstrap/3.3.6/js/bootstrap.min.js" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></script></head><body><p>标签式的导航菜单</p><ul class="nav nav-tabs">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">SVN</a></li>
<li><a href="#">iOS</a></li>
<li><a href="#">VB.Net</a></li>
<li><a href="#">Java</a></li>
<li><a href="#">PHP</a></li></ul></body></html>
结果如下所示: 胶囊式的导航菜单基本的胶囊式导航菜单如果需要把标签改成胶囊的样式,只需要使用 class .nav-pills 代替 .nav-tabs 即可,其他的步骤与上面相同。 下面的实例演示了这点: <!DOCTYPE html><html><head>
<title>Bootstrap 实例 - 基本的胶囊式导航菜单</title>
<link href="//cdn.bootcss.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="stylesheet">
<script src="//cdn.bootcss.com/jquery/2.1.1/jquery.min.js" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></script>
<script src="//cdn.bootcss.com/bootstrap/3.3.6/js/bootstrap.min.js" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></script></head><body><p>基本的胶囊式导航菜单</p><ul class="nav nav-pills">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">SVN</a></li>
<li><a href="#">iOS</a></li>
<li><a href="#">VB.Net</a></li>
<li><a href="#">Java</a></li>
<li><a href="#">PHP</a></li></ul></body></html>
结果如下所示: 垂直的胶囊式导航菜单您可以在使用 class .nav、.nav-pills 的同时使用 class .nav-stacked,让胶囊垂直堆叠。 下面的实例演示了这点: <!DOCTYPE html><html><head>
<title>Bootstrap 实例 - 垂直的胶囊式导航菜单</title>
<link href="//cdn.bootcss.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="stylesheet">
<script src="//cdn.bootcss.com/jquery/2.1.1/jquery.min.js" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></script>
<script src="//cdn.bootcss.com/bootstrap/3.3.6/js/bootstrap.min.js" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></script></head><body><p>垂直的胶囊式导航菜单</p><ul class="nav nav-pills nav-stacked">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">SVN</a></li>
<li><a href="#">iOS</a></li>
<li><a href="#">VB.Net</a></li>
<li><a href="#">Java</a></li>
<li><a href="#">PHP</a></li></ul></body></html>
结果如下所示: 两端对齐的导航您可以在屏幕宽度大于 768px 时,通过在分别使用 .nav、.nav-tabs 或 .nav、.nav-pills 的同时使用 class .nav-justified,让标签式或胶囊式导航菜单与父元素等宽。在更小的屏幕上,导航链接会堆叠。 下面的实例演示了这点: <!DOCTYPE html><html><head>
<title>Bootstrap 实例 - 两端对齐的导航元素</title>
<link href="//cdn.bootcss.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="stylesheet">
<script src="//cdn.bootcss.com/jquery/2.1.1/jquery.min.js" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></script>
<script src="//cdn.bootcss.com/bootstrap/3.3.6/js/bootstrap.min.js" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></script></head><body><p>两端对齐的导航元素</p><ul class="nav nav-pills nav-justified">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">SVN</a></li>
<li><a href="#">iOS</a></li>
<li><a href="#">VB.Net</a></li>
<li><a href="#">Java</a></li>
<li><a href="#">PHP</a></li></ul><br><br><br><ul class="nav nav-tabs nav-justified">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">SVN</a></li>
<li><a href="#">iOS</a></li>
<li><a href="#">VB.Net</a></li>
<li><a href="#">Java</a></li>
<li><a href="#">PHP</a></li></ul></body></html>
结果如下所示: 禁用链接对每个 .nav class,如果添加了 .disabled class,则会创建一个灰色的链接,同时禁用了该链接的 :hover 状态,如下面的实例所示: <!DOCTYPE html><html><head>
<title>Bootstrap 实例 - 导航元素中的禁用链接</title>
<link href="//cdn.bootcss.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="stylesheet">
<script src="//cdn.bootcss.com/jquery/2.1.1/jquery.min.js" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></script>
<script src="//cdn.bootcss.com/bootstrap/3.3.6/js/bootstrap.min.js" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></script></head><body><p>导航元素中的禁用链接</p><ul class="nav nav-pills">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">SVN</a></li>
<li class="disabled"><a href="#">iOS(禁用链接)</a></li>
<li><a href="#">VB.Net</a></li>
<li><a href="#">Java</a></li>
<li><a href="#">PHP</a></li></ul><br><br><ul class="nav nav-tabs">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">SVN</a></li>
<li><a href="#">iOS</a></li>
<li class="disabled"><a href="#">VB.Net(禁用链接)</a></li>
<li><a href="#">Java</a></li>
<li><a href="#">PHP</a></li></ul> </body></html>
结果如下所示: 该 class 只会改变 <a> 的外观,不会改变它的功能。在这里,您需要使用自定义的 JavaScript 来禁用链接。 下拉菜单导航菜单与下拉菜单使用相似的语法。默认情况下,列表项的锚与一些数据属性协同合作来触发带有 .dropdown-menu class 的无序列表。 带有下拉菜单的标签向标签添加下拉菜单的步骤如下: <!DOCTYPE html><html><head>
<title>Bootstrap 实例 - 带有下拉菜单的标签</title>
<link href="//cdn.bootcss.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="stylesheet">
<script src="//cdn.bootcss.com/jquery/2.1.1/jquery.min.js" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></script>
<script src="//cdn.bootcss.com/bootstrap/3.3.6/js/bootstrap.min.js" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" ></script></head><body><p>带有下拉菜单的标签</p><ul class="nav nav-tabs">
<li class="active"><a href="#">Home</a></li>
<li><a href="#">SVN</a></li>
<li><a href="#">iOS</a></li>
<li><a href="#">VB.Net</a></li>
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">
Java <span class="caret"></span>
</a>
<ul class="dropdown-menu">
<li><a href="#">Swing</a></li>
<li><a href="#">jMeter</a></li>
<li><a href="#">EJB</a></li>
<li class="divider"></li>
<li><a href="#">分离的链接</a></li>
</ul>
</li>
<li><a href="#">PHP</a></li></ul></body></html>
结果如下所示: 带有下拉菜单的胶囊步骤与创建带有下拉菜单的标签相同,只是需要把 .nav-tabs class 改为 .nav-pills,如下面的实例所示: <!DOCTYPE html><html><head>
<title>Bootstrap 实例 - 带有下拉菜单的胶囊</title>
<link href="//cdn.bootcss.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="external nofollow" target="_blank" rel="stylesheet">

<li class="active"><a href="#">Home</a></li>
<li><a href="#">SVN</a></li>
<li><a href="#">iOS</a></li>
<li><a href="#">VB.Net</a></li>
<li class="dropdown">
<a class="dropdown-toggle" data-toggle="dropdown" href="#">
Java <span class="caret"></span>
</a>
<ul class="dropdown-menu">
<li><a href="#">Swing</a></li>
<li><a href="#">jMeter</a></li>
<li><a href="#">EJB</a></li>
<li class="divider"></li>
<li><a href="#">分离的链接</a></li>
</ul>
</li>
<li><a href="#">PHP</a></li></ul></body></html>
