从 Bootstrap 4 开始，Navbar 是 flexbox，因此创建全角搜索输入更容易.您可以简单地使用 w-100 和 d-inline 实用程序类:

这是另一个示例，搜索输入 outside 位于折叠导航栏:
<nav class="navbar navbar-expand-md navbar-dark bg-dark"><div class="d-flex flex-grow-1"><a href="/" class="navbar-brand">Codeply</a><form class="mr-2 my-auto w-100 d-inline-block order-1"><div class="input-group"><input type="text" class="form-control border border-right-0" placeholder="搜索..."><span class="input-group-append"><button class="btn btn-outline-light border border-left-0" type="button"><i class="fa fa-search"></i></span>
</表单>
<button class="navbar-toggler order-0" type="button" data-toggle="collapse" data-target="#navbar7"><span class="navbar-toggler-icon"></span><div class="navbar-collapse collapse flex-shrink-1 flex-grow-0 order-last" id="navbar7"><ul class="navbar-nav">..
</nav>

而且，最后另一个示例改变了桌面/移动设备上的搜索宽度(只有全宽在移动设备上)来自我的在这里回答
引导程序 3(原始答案)
您可以像这样在最后一个导航栏 li 上使用 text-truncate hack..
<form class="input-group"><input class="form-control" name="search" placeholder="Search Here" autocomplete="off" autofocus="autofocus" type="text"><div class="input-group-btn"><button class="btn btn-outline-success" type="submit">搜索</button>
</表单>
在 Bootstrap 4 中，将设置 text-truncate:
溢出:隐藏；空白:nowrap；
这使搜索表单能够填充剩余的宽度而不是换行.

另一种选择是使用table-cell:
<div class="table-cell fill-width"><input class="form-control" name="search" placeholder="Search Here" autocomplete="off" autofocus="autofocus" type="text">
<div class="table-cell"><button class="btn btn-outline-success" type="submit">搜索</button>
</表单>

How to make 100% width of the search input in navbar?
The field is limited in width:
<nav class="navbar navbar-light navbar-dark bg-inverse">
<a class="navbar-brand" href="#">Navbar</a>
<ul class="nav navbar-nav">
<li class="nav-item active">
<a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Features</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Pricing</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">About</a>
</li>
</ul>
<ul class="nav navbar-nav pull-xs-right">
<li class="nav-item">
<form class="form-inline ">
<input class="form-control" type="text" placeholder="Search">
<button class="btn btn-outline-success" type="submit">Search</button>
</form>
</li>
<li class="nav-item">
<a class="nav-link" href="#">User Name</a>
</li>
</ul>
</nav>

Updated 2019
As of Bootstrap 4 the Navbar is flexbox so creating a full-width search input is easier. You can simply use w-100 and d-inline utility classes:
<form class="mx-2 my-auto d-inline w-100">
<div class="input-group">
<input type="text" class="form-control" placeholder="...">
<span class="input-group-append">
<button class="btn btn-outline-secondary" type="button">GO</button>
</span>
</div>
</form>

Here's another example with the search input outside of the collapsing navbar:
<!-- search input not in navbar collapse -->
<nav class="navbar navbar-expand-md navbar-dark bg-dark">
<div class="d-flex flex-grow-1">
<a href="/" class="navbar-brand">Codeply</a>
<form class="mr-2 my-auto w-100 d-inline-block order-1">
<div class="input-group">
<input type="text" class="form-control border border-right-0" placeholder="Search...">
<span class="input-group-append">
<button class="btn btn-outline-light border border-left-0" type="button">
<i class="fa fa-search"></i>
</button>
</span>
</div>
</form>
</div>
<button class="navbar-toggler order-0" type="button" data-toggle="collapse" data-target="#navbar7">
<span class="navbar-toggler-icon"></span>
</button>
<div class="navbar-collapse collapse flex-shrink-1 flex-grow-0 order-last" id="navbar7">
<ul class="navbar-nav">
..
</ul>
</div>
</nav>

And, finally another example that varies the width of the search on desktop/mobile (only full width on mobile) from my answer here
Bootstrap 3 (original answer)
You can use the text-truncate hack on the last navbar li like this..
<li class="text-truncate">
<form class="input-group">
<input class="form-control" name="search" placeholder="Search Here" autocomplete="off" autofocus="autofocus" type="text">
<div class="input-group-btn">
<button class="btn btn-outline-success" type="submit">Search</button>
</div>
</form>
</li>
In Bootstrap 4, text-truncate will set:
overflow: hidden;
white-space: nowrap;
This enables the search form to fill the remaining width and not wrap.

Another option is to use table-cell:
<form>
<div class="table-cell"> </div>
<div class="table-cell fill-width">
<input class="form-control" name="search" placeholder="Search Here" autocomplete="off" autofocus="autofocus" type="text">
</div>
<div class="table-cell">
<button class="btn btn-outline-success" type="submit">Search</button>
</div>
</form>
