输入框组 · Bootstrap 6.0 中文文档

输入组将附加元素添加到文本输入字段。附加元素可以是文本、按钮或按钮组。可以使用表单字段添加标签、帮助文本和验证样式。

@example.com

HTML

<div class="input-group">
  <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">
  <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>

示例

在输入框的任一侧放置一个附加组件或按钮。你也可以在输入框的两侧各放置一个。记住要将 <label> 放在输入组的外侧。

带表单字段

将 .input-group 包装在 .form-field 中，以将其与标签和描述文本配对。

你的自定义网址

https://example.com/

为你的个人资料选择一个独特的 URL。

HTML

<div class="form-field">
  <label for="inputGroupField" class="form-label">Your vanity URL</label>
  <div class="input-group">
    <span class="input-group-text">https://example.com/</span>
    <input type="text" class="form-control" id="inputGroupField" placeholder="username">
  </div>
  <small class="form-text">Choose a unique URL for your profile.</small>
</div>

按钮

使用按钮替代插件以支持交互选项。

HTML

<div class="input-group">
  <button class="btn-outline theme-secondary input-group-btn" type="button" id="button-addon">Button</button>
  <input type="text" class="form-control" placeholder="" aria-label="Example text with button addon" aria-describedby="button-addon">
</div>

文本区

输入组会根据文本区域元素的高度进行调整。

带有文本区域

HTML

<div class="input-group">
  <span class="input-group-text">With textarea</span>
  <textarea class="form-control" aria-label="With textarea"></textarea>
</div>

选择

选项

HTML

<div class="input-group mb-3">
  <label class="input-group-text" for="inputGroupSelect01">Options</label>
  <select class="form-control" id="inputGroupSelect01">
    <option selected>Choose...</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
  </select>
</div>

<div class="input-group mb-3">
  <select class="form-control" id="inputGroupSelect02">
    <option selected>Choose...</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
  </select>
  <label class="input-group-text" for="inputGroupSelect02">Options</label>
</div>

<div class="input-group mb-3">
  <button class="btn-outline theme-secondary input-group-btn" type="button">Button</button>
  <select class="form-control" id="inputGroupSelect03" aria-label="Example select with button addon">
    <option selected>Choose...</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
  </select>
</div>

<div class="input-group">
  <select class="form-control" id="inputGroupSelect04" aria-label="Example select with button addon">
    <option selected>Choose...</option>
    <option value="1">One</option>
    <option value="2">Two</option>
    <option value="3">Three</option>
  </select>
  <button class="btn-outline theme-secondary input-group-btn" type="button">Button</button>
</div>

文件输入

上传

HTML

<div class="input-group mb-3">
  <label class="input-group-text" for="inputGroupFile01">Upload</label>
  <input type="file" class="form-control" id="inputGroupFile01">
</div>

<div class="input-group mb-3">
  <input type="file" class="form-control" id="inputGroupFile02">
  <label class="input-group-text" for="inputGroupFile02">Upload</label>
</div>

<div class="input-group mb-3">
  <button class="btn-outline theme-secondary input-group-btn" type="button" id="inputGroupFileAddon03">Button</button>
  <input type="file" class="form-control" id="inputGroupFile03" aria-describedby="inputGroupFileAddon03" aria-label="Upload">
</div>

<div class="input-group">
  <input type="file" class="form-control" id="inputGroupFile04" aria-describedby="inputGroupFileAddon04" aria-label="Upload">
  <button class="btn-outline theme-secondary input-group-btn" type="button" id="inputGroupFileAddon04">Button</button>
</div>

复选框和单选按钮

将任何复选框或单选按钮放置在输入组的附加组件中，而不是文本中。

HTML

<div class="input-group mb-3">
  <div class="input-group-text">
    <input type="checkbox" class="check" 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 type="radio" class="radio" aria-label="Radio button for following text input">
  </div>
  <input type="text" class="form-control" aria-label="Text input with radio button">
</div>

多个输入

虽然从视觉上支持多个 <input>，但验证样式仅适用于具有单个 <input> 的输入组。

名字和姓氏

HTML

<div class="input-group">
  <input type="text" aria-label="First name" class="form-control">
  <input type="text" aria-label="Middle name" class="form-control">
  <input type="text" aria-label="Last name" class="form-control">
</div>

<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>

<div class="input-group">
    <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>

多个插件

支持多种附加组件，并且可以与复选框和单选按钮输入版本混合使用。

    <svg class="bi"><use href="#chevron-expand"></use></svg>

  </div>
</div>

边框半径

有时候构建这些组件会变得复杂，而 CSS 选择器的能力是有限的。我们已经考虑了大多数常见的使用场景，但如果你需要额外提供一个元素并跳过 border-radius 的逻辑，请将 .input-group-ignore 类添加到该元素上。

考虑这个额外的隐藏输入示例：

@ [!代码高亮]

HTML

<div class="input-group">
  <span class="input-group-text" id="visible-addon">@</span>
  <input type="text" class="form-control" placeholder="Username" aria-label="Username" aria-describedby="visible-addon">
  <input type="text" class="form-control input-group-ignore d-none" placeholder="Hidden input" aria-label="Hidden input" aria-describedby="visible-addon">
</div>

尺寸

将相对表单尺寸类添加到.input-group本身，内部内容将自动调整大小—无需在每个元素上重复使用表单控件尺寸类。

不支持单个输入组元素的尺寸调整。

小

默认

大

HTML

<div class="input-group input-group-sm">
  <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">
  <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>

CSS

变量

输入组附加组件在.input-group-text上使用本地 CSS 变量进行实时自定义。CSS 变量的值是由每个组件独有的 Sass map生成的，并应用于上述类。

scss/表单/_输入组.scss

// stylelint-disable-next-line scss/dollar-variable-default
$input-group-addon-tokens: defaults(
  (
    --input-group-addon-padding-y: var(--btn-input-padding-y),
    --input-group-addon-padding-x: var(--btn-input-padding-x),
    --input-group-addon-font-size: var(--btn-input-font-size),
    --input-group-addon-line-height: var(--btn-input-line-height),
    --input-group-addon-color: var(--fg-body),
    --input-group-addon-bg: var(--bg-2),
    --input-group-addon-border-color: var(--border-color),
  ),
  $input-group-addon-tokens
);

Sass 列表

我们使用 Sass 列表来定义输入组的大小，因此你可以通过获取每个大小的关联根变量来轻松添加或修改大小。该列表通常应与定义的大小相匹配 $form-control-sizes Sass map输入 _form-control.scss.

scss/表单/_输入组.scss

$input-group-sizes: ();
// stylelint-disable-next-line scss/dollar-variable-default
$input-group-sizes: defaults(
  ("sm", "lg"),
  $input-group-sizes
);
