【中文标题】如何在 Bootstrap 3 的导航栏中添加带有图标的搜索框？【英文标题】：How to add a search box with icon to the navbar in Bootstrap 3? 【发布时间】：2013-09-08 07:24:42 【问题描述】：我正在使用新的 Twitter Bootstrap 3，并尝试将这样的搜索框（如下）放在顶部导航栏中：
在 Bootstrap 2 中，可以这样做：
<form class="form-search" method="get" id="s" action="/">
<div class="input-append">
<input type="text" class="input-medium search-query" name="s" placeholder="Search" value="">
<button type="submit" class="add-on"><i class="icon-search"></i></button>
</div>
</form>
但我不确定如何在 Bootstrap 3 中生成相同的内容，因为发生了很大变化。
Bootstrap 3 中导航栏搜索框表单的默认 html 为：
<form class="navbar-form navbar-left" role="search">
<div class="form-group">
<input type="text" class="form-control" placeholder="Search">
</div>
<button type="submit" class="btn btn-default">Submit</button>
</form>
如何修改它以达到我的需要？

<div class="navbar navbar-inverse navbar-static-top" role="navigation">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target=".navbar-ex1-collapse">
<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" rel="home" href="/" title="Aahan Krish's Blog - Homepage">ITSMEEE</a>
</div>
<div class="collapse navbar-collapse navbar-ex1-collapse">
<ul class="nav navbar-nav">
<li><a href="/topic/notes/">/notes</a></li>
<li><a href="/topic/dev/">/dev</a></li>
<li><a href="/topic/good-reads/">/good-reads</a></li>
<li><a href="/topic/art/">/art</a></li>
<li><a href="/topic/bookmarks/">/bookmarks</a></li>
<li><a href="/all-topics/">/all</a></li>
</ul>
<div class="col-sm-3 col-md-3 pull-right">
<form class="navbar-form" role="search">
<div class="input-group">
<input type="text" class="form-control" placeholder="Search" name="srch-term" id="srch-term">
<div class="input-group-btn">
<button class="btn btn-default" type="submit"><i class="glyphicon glyphicon-search"></i></button>
</div>
</div>
</form>
</div>
</div>
</div>
更新：见JSFiddle
【讨论】：
这使搜索框看起来像我想要的那样，但会破坏导航栏。如果不破坏搜索框，我就无法修复它，反之亦然。 :-/ 这是截图：i.stack.imgur.com/vTfvX.png @its_me：我不知道为什么它会为你打破。在发布之前，我在一个实时网站上对其进行了完全测试。也许它是你插入它的地方。我将使用我正在使用的完整导航条码更新答案。我个人建议右对齐搜索表单，但这取决于您。 Phil，我还没有现场测试。所以，我正在通过替换官方引导站点上的示例来测试它，这里：getbootstrap.com/components/#navbar -- 如果您想尝试，请尝试，否则我会在我的站点启动时再次检查并通知您。感谢您尝试提供帮助。 +1 我已经分叉了你的 Fiddle 并对其进行了调整：JSFiddle 基于BS3 docs for Button addons，我认为这是你将得到的最好的。请注意，我删除了不可见的字段标签，它返回左侧的角半径。我会再次更新答案代码。 我没有那么容易放弃。我更新了 Fiddle，并测试了 IE10、Firefox 和 Chrome。文本区域的宽度随着窗口宽度的变化而略有不同，但我认为它具有您正在寻找的效果。【参考方案2】：这是在不添加任何自定义 CSS 的情况下我能得到的最接近的结果（在提出问题时我已经想到了这一点；我想我必须坚持这个）：
以及使用中的标记：
<form class="navbar-form navbar-left" role="search">
<div class="form-group">
<input type="text" class="form-control" placeholder="Search">
</div>
<button type="submit" class="btn btn-default">
<span class="glyphicon glyphicon-search"></span>
</button>
</form>
PS：当然，这可以通过在按钮上添加负号margin-left (-4px) 并删除侧面input 和button 上的border-radius 来解决遇到。但这个问题的重点是让它在没有任何自定义 CSS 的情况下工作。
【讨论】：
【参考方案3】：您可以使用 Bootstrap 3 中的分段按钮示例：
<form action="" class="navbar-form navbar-right">
<div class="input-group">
<input type="Search" placeholder="Search..." class="form-control" />
<div class="input-group-btn">
<button class="btn btn-info">
<span class="glyphicon glyphicon-search"></span>
</button>
</div>
</div>
</form>
【讨论】：
【参考方案4】：我尝试了@PhilNicholas 的代码，得到了与@its_me 在导航栏下一行显示搜索栏的cmets 中所说的相同的问题，我发现form 需要添加一个属性width .
<form role="search" style="width: 15em; margin: 0.3em 2em;">
<div class="input-group">
<input type="text" class="form-control" placeholder="Search">
<div class="input-group-btn">
<button type="submit" class="btn btn-default">
<span class="glyphicon glyphicon-search"></span>
</button>
</div>
</div>
</form>
【讨论】：
关闭，我发现我需要为输入组添加一个宽度。<div class="input-group" style="width:15em;">【参考方案5】：
这是我为我的网站实现的，如果有人有更多没有的菜单项和更长的搜索栏可以使用这个
这里是代码
<style>
.navbar-inverse .navbar-nav > li > a

.navbar-inverse .navbar-nav > li > a:hover
