Question

所以我遇到了一个问题，由于某些原因你无法使用tab键从我的Bootstrap导航栏中选择下拉列表？我担心这意味着人们使用屏幕阅读器，这样就无法浏览网站。它似乎适用于其他引导程序站点，所以我不知道什么是错的。

这是我的代码：

<!DOCTYPE html>
<html lang="en">
  <head>
  <meta charset="utf-8">
  <meta http-equiv="X-UA-Compatible" content="IE=edge">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <title>yiskah @ spooky camp</title>
  <!-- CSS -->
  <link href="../css/bootstrap.css" rel="stylesheet">
  <link href="../css/navbar-static-top.css" rel="stylesheet">
  <link href="../css/bootstrap-accessibility.css" rel="stylesheet">
  <link href="../css/default.css" rel="stylesheet">
</head>
<body>
  <a href="#content" class="sr-only sr-only-focusable">Skip to main content</a>
  <!-- Static navbar -->
   <nav class="navbar navbar-default navbar-static-top" role="navigation">
    <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="../index.html">brand</a>
    </div>
    <div id="navbar" class="navbar-collapse collapse">
      <ul class="nav navbar-nav">
        <li><a href="../index.html">Home</a></li>
        <li class="dropdown">
          <a class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Projects<span class="caret"></span></a>
            <ul class="dropdown-menu" role="menu">
              <li><a href="../sorry">Robo-Apologizer</a></li>
                <li><a href="../photoshop">Photoshop Idea Generator</a></li>
                <li><a href="../diviii">Div III Generator</a></li>
            </ul>
        </li>
          <li class="dropdown">
          <a class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Written Work<span class="caret"></span></a>
            <ul class="dropdown-menu" role="menu">
                <li><a href="../lexrep">Lexical Replacement</a></li>
                <li><a href="../mannequin">Mannequin Allies</a></li>
            </ul>
        </li>
        <li class="dropdown">
          <a class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">@Elsewhere <span class="caret"></span></a>
          <ul class="dropdown-menu" role="menu">
            <li><a>(links to social profiles)</a></li>
            <li><a>(one of my social links is here)</a></li>
            <li class="divider"></li>
            <li class="dropdown-header">Contact</li>
            <li><a>(one of my emails goes here)</a></li>
            <li><a>(I put another email here)</a></li>
          </ul>
        </li>
      </ul>
    </div><!--/.nav-collapse -->

我没有修改任何默认的bootstrap代码。我在尝试实现导航栏的其他网站上遇到此问题。但它在bootstrap网站上的示例中运行良好吗？

有什么想法吗？

您在所有下拉切换锚点上都缺少href属性。有关修复版本，请参阅this bootply。

此：

<a class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Projects<span class="caret"></span></a>

需要这样：

 <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Projects<span class="caret"></span></a>

或者这个：

 <a href="javascript:void(0)" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Projects<span class="caret"></span></a>

或者这个：

 <a tabindex="0" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-expanded="false">Projects<span class="caret"></span></a>

无法选项卡以选择Bootstrap Navbar中的下拉菜单
