我有一个内联表单,旁边有一个搜索栏和一个搜索按钮。如何强制input-group
div跨越Bootstrap 4中的整个列,最好不使用自定义CSS?
<div class="container">
<div class="row">
<div class="col-md-12">
<form class="form-inline" action="/search" accept-charset="UTF-8" method="get">
<div class="input-group">
<input type="text" name="search" id="search" value="test" placeholder="Search accounts, contracts and transactions" class="form-control">
<span class="input-group-btn">
<input type="submit" name="commit" value="Search" class="btn btn-primary" data-disable-with="Search">
</span>
</div>
</form>
</div>
</div>
</div>

删除form-inline
..
<div class="container">
<div class="row">
<div class="col-md-12">
<form action="" accept-charset="UTF-8" method="get">
<div class="input-group">
<input type="text" name="search" id="search" value="test" placeholder="Search accounts, contracts and transactions" class="form-control">
<span class="input-group-btn">
<input type="submit" name="commit" value="Search" class="btn btn-primary" data-disable-with="Search">
</span>
</div>
</form>
</div>

另一个选项 - 在xs上垂直堆叠的全宽输入:
<div class="row">
<div class="col-md-12">
<form class="row">
<div class="col-12 col-sm pr-sm-0">
<input type="text" name="search" id="search" value="test" placeholder="Search accounts, contracts and transactions" class="form-control">
</div>
<div class="col-12 col-sm-auto pl-sm-0">
<input type="button" name="commit" value="Search" class="btn btn-primary btn-block">
</div>
</form>
</div>
</div>

Bootstrap 4.3现在具有一个表格网格,它允许您指定列宽。这就是我最终将输入表单和按钮对齐为所需宽度的方式。
https://getbootstrap.com/docs/4.3/components/forms/#form-grid
<form class="form" method="get" action="/products">
<div class="row">
<div class="col-md-6 offset-md-2">
<input type="text" class="form-control" name="search" placeholder="search products">
</div>
<div class="col-md-2">
<button type="submit" class="btn btn-outline-primary mb-2">Search</button>
</div>
</div>
</form>

您可以通过三种可能的方式来实现以下两个布局选项:
See my Codeply.com demonstrating all solutions detailed below...
只需将类flex-fill
添加到您的<div class="form-group">
。
请注意,您在上面的原始示例代码中,Bootstrap 4已从使用input-group-btn
更改为input-group-append
,以使按钮坚持关键字字段并正确处理圆角。
最后,我还添加了一个aria-label
属性,以满足您的示例的可访问性要求。
<div class="container">
<div class="row">
<div class="col-md-12">
<form class="form-inline" action="/search" accept-charset="UTF-8" method="get">
<div class="input-group flex-fill">
<input type="search" name="search" id="search" value="" placeholder="Full-width search form with sticky button" class="form-control" aria-label="Search this site">
<div class="input-group-append">
<input type="submit" name="commit" value="Search" class="btn btn-primary" data-disable-with="Search">
</div>
</div>
</form>
</div>
</div>
</div>
对于此解决方案,您有两种选择,具体取决于您所需的HTML结构和项目的需求。
首先,您可以删除所有包装div并将类flex-fill mr-2
添加到<input class="form-control">
。这是最简单的选择。
<div class="container">
<div class="row">
<div class="col-md-12">
<form class="form-inline" action="/search" accept-charset="UTF-8" method="get">
<input type="search" name="search" id="search" value="" placeholder="Full-width search form with separate button w/o wrapper div" class="flex-fill mr-2 form-control" aria-label="Search this site">
<input type="submit" name="commit" value="Search" class="btn btn-primary" data-disable-with="Search">
</form>
</div>
</div>
</div>
如果有机会,我会选择这种解决方案,因为它可以生成最干净的HTML;)
如果您的表单需要一些包装div(例如,由于与CMS对抗),则必须与放置类的位置进行斗争:首先,将<div class="input-group">
替换为<div class="flex-fill mr-2">
,添加类w-100
到<input class="form-control">
,最后删除<div class="input-group-append">
包装器,然后将提交按钮移至flex-fill包装器的外部。
<div class="container">
<div class="row">
<div class="col-md-12">
<form class="form-inline" action="/search" accept-charset="UTF-8" method="get">
<div class="flex-fill mr-2">
<input type="search" name="search" id="search" value="" placeholder="Full-width search form with separate button w/ wrapper div" class="form-control w-100" aria-label="Search this site">
</div>
<input type="submit" name="commit" value="Search" class="btn btn-primary" data-disable-with="Search">
</form>
</div>
</div>
</div>
最终,您的选择可能会归结为您希望它在移动设备上的工作方式。您当然可以进一步纠缠代码,但是值得关注以下断点:
