基本实例
在输入的任一侧放置一个加载项或按钮。你也可以在输入的两边各放一个。记住将<label>
放在输入组之外。

@example.com
https://example.com/users/

With textarea
<div class="input-group mb-3">
<span class="input-group-text" id="basic-addon1">@</span>
<input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="basic-addon1">
</div>
<div class="input-group mb-3">
<input type="text" class="form-control" placeholder="Recipient's username" aria-label="Recipient's username" aria-describedby="basic-addon2">
<span class="input-group-text" id="basic-addon2">@example.com</span>
</div>
<label for="basic-url" class="form-label">Your vanity URL</label>
<div class="input-group mb-3">
<span class="input-group-text" id="basic-addon3">https://example.com/users/</span>
<input type="text" class="form-control" id="basic-url" aria-describedby="basic-addon3">
</div>
<div class="input-group mb-3">
<span class="input-group-text">$</span>
<input type="text" class="form-control" aria-label="Amount (to the nearest dollar)">
<span class="input-group-text">.00</span>
</div>
<div class="input-group mb-3">
<input type="text" class="form-control" placeholder="Username" aria-label="Username">
<span class="input-group-text">@</span>
<input type="text" class="form-control" placeholder="Server" aria-label="Server">
</div>
<div class="input-group">
<span class="input-group-text">With textarea</span>
<textarea class="form-control" aria-label="With textarea"></textarea>
</div>
包裹输入框
默认情况下,输入组通过flex-wrap: wrap
进行包裹,以便在输入组中容纳自定义表单字段验证。你可以用.flex-nowrap
禁用它。
@
<div class="input-group flex-nowrap">
<span class="input-group-text" id="addon-wrapping">@</span>
<input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="addon-wrapping">
</div>
调整大小
将相对窗体大小调整类添加到.input-group
本身和其中的内容将自动调整大小,无需在每个元素上重复窗体控件大小调整类
不支持对单个输入组元素进行调整。
Small
Default
Large
<div class="input-group input-group-sm mb-3">
<span class="input-group-text" id="inputGroup-sizing-sm">Small</span>
<input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-sm">
</div>
<div class="input-group mb-3">
<span class="input-group-text" id="inputGroup-sizing-default">Default</span>
<input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-default">
</div>
<div class="input-group input-group-lg">
<span class="input-group-text" id="inputGroup-sizing-lg">Large</span>
<input type="text" class="form-control" aria-label="Sizing example input" aria-describedby="inputGroup-sizing-lg">
</div>
复选框和单选框
在输入组的插件中放置任何复选框或单选选项,而不是文本。
<div class="input-group mb-3">
<div class="input-group-text">
<input class="form-check-input" type="checkbox" value="" aria-label="Checkbox for following text input">
</div>
<input type="text" class="form-control" aria-label="Text input with checkbox">
</div>
<div class="input-group">
<div class="input-group-text">
<input class="form-check-input" type="radio" value="" aria-label="Radio button for following text input">
</div>
<input type="text" class="form-control" aria-label="Text input with radio button">
</div>
多重输入
虽然多个
<input>
在视觉上受支持,但验证样式仅适用于具有单个<input>
的输入组。
First and last name
<div class="input-group">
<span class="input-group-text">First and last name</span>
<input type="text" aria-label="First name" class="form-control">
<input type="text" aria-label="Last name" class="form-control">
</div>
多重插件
支持多个插件,可以与复选框和无线电输入版本混合。
