Bootstrap 简明教程

Bootstrap - Button Group

本章将讨论 Bootstrap 按钮组。Bootstrap 按钮组将多个按钮水平或垂直地放在一行上。

Basic example

你可以使用 .btn 中的 .btn-group 类创建一个按钮组。

Example

您可以使用*编辑和运行*选项编辑并尝试运行此代码。

    <!DOCTYPE html>
    <html lang="en">
    <head>
      <title>Bootstrap - Button Groups</title>
      <meta charset="UTF-8">
      <meta http-equiv="X-UA-Compatible" content="IE=edge">
      <meta name="viewport" content="width=device-width, initial-scale=1.0">
      <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/css/bootstrap.min.css" rel="stylesheet">
      <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/js/bootstrap.bundle.min.js"></script>
    </head>
    <body>
      <div class="btn-group" role="group" aria-label="Basic Example">
        <button type="button" class="btn btn-info">Register</button>
        <button type="button" class="btn btn-danger">Submit</button>
        <button type="button" class="btn btn-warning">Cancel</button>
      </div>
    </body>
    </html>

  1. 作为 .nav navigation components 的替代，这些类也可以应用于一组链接。

  2. 你可以通过使用 .active 类来突出显示一个链接。

Example

您可以使用*编辑和运行*选项编辑并尝试运行此代码。

  <!DOCTYPE html>
  <html lang="en">
  <head>
    <title>Bootstrap - Button Groups</title>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/css/bootstrap.min.css" rel="stylesheet">
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/js/bootstrap.bundle.min.js"></script>
  </head>
  <body>
    <div class="btn-group my-2">
      <a href="#" class="btn btn-success active" aria-current="page">Registration Link</a>
      <a href="#" class="btn btn-success">Submit</a>
      <a href="#" class="btn btn-success">Cancel</a>
    </div>
  </body>
  </html>

Mixed styles

对于样式混排的按钮组，可以创建一个按钮组，其中每个按钮有不同的背景颜色。

Example

您可以使用*编辑和运行*选项编辑并尝试运行此代码。

  <!DOCTYPE html>
  <html lang="en">
  <head>
    <title>Bootstrap - Button Groups</title>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/css/bootstrap.min.css" rel="stylesheet">
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/js/bootstrap.bundle.min.js"></script>
  </head>
  <body>
    <div class="btn-group mt-2" role="group" aria-label="Mixed styles">
      <button type="button" class="btn btn-info">Register</button>
      <button type="button" class="btn btn-success">Cancel</button>
      <button type="button" class="btn btn-warning">Submit</button>
    </div>
  </body>
  </html>

Outlined styles

使用比如 btn-outline-primary 、 btn-outline-dark 等按钮样式仅展示组中按钮元素边框的颜色。

Example

您可以使用*编辑和运行*选项编辑并尝试运行此代码。

  <!DOCTYPE html>
  <html lang="en">
  <head>
    <title>Bootstrap - Button Groups</title>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/css/bootstrap.min.css" rel="stylesheet">
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/js/bootstrap.bundle.min.js"></script>
  </head>
  <body>
    <div class="btn-group my-2" role="group" aria-label="Basic outlined">
      <button type="button" class="btn btn-outline-primary">Register</button>
      <button type="button" class="btn btn-outline-dark">Submit</button>
      <button type="button" class="btn btn-outline-warning">Cancel</button>
    </div>
  </body>
  </html>

Checkbox and radio button groups

使用类似复选框切换按钮的按钮，我们可以创建一个干净漂亮的按钮组。若要实现此操作，请使用 .btn-check 类和 type="checkbox" 。

Example

您可以使用*编辑和运行*选项编辑并尝试运行此代码。

  <!DOCTYPE html>
  <html lang="en">
  <head>
    <title>Bootstrap - Button Groups</title>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/css/bootstrap.min.css" rel="stylesheet">
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/js/bootstrap.bundle.min.js"></script>
  </head>
  <body>
    <div class="btn-group my-2" role="group" aria-label="checkbox toggle button group">
      <input type="checkbox" class="btn-check" id="btnCheckbox1" autocomplete="off">
      <label class="btn btn-outline-primary" for="btnCheckbox1">Register</label>

      <input type="checkbox" class="btn-check" id="btnCheckbox2" autocomplete="off">
      <label class="btn btn-outline-warning" for="btnCheckbox2">Submit</label>

      <input type="checkbox" class="btn-check" id="btnCheckbox3" autocomplete="off">
      <label class="btn btn-outline-info" for="btnCheckbox3">Cancel</label>
    </div>
  </body>
  </html>

使用类似于单选按钮的按钮切换按钮，我们可以创建一个无缝外观的按钮组。要实现此功能，请使用 .btn-check 和 type="radio" 。

Example

您可以使用*编辑和运行*选项编辑并尝试运行此代码。

  <!DOCTYPE html>
  <html lang="en">
  <head>
    <title>Bootstrap - Button Groups</title>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/css/bootstrap.min.css" rel="stylesheet">
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/js/bootstrap.bundle.min.js"></script>
  </head>
  <body>
    <div class="btn-group" role="group" aria-label="radio toggle button group">
      <input type="radio" class="btn-check" name="radioButton" id="buttonRadio1" autocomplete="off" checked>
      <label class="btn btn-outline-primary" for="buttonRadio1">Register</label>

      <input type="radio" class="btn-check" name="radioButton" id="buttonRadio2" autocomplete="off">
      <label class="btn btn-outline-warning" for="buttonRadio2">Submit</label>

      <input type="radio" class="btn-check" name="radioButton" id="buttonRadio3" autocomplete="off">
      <label class="btn btn-outline-success" for="buttonRadio3">Cancel</label>
    </div>
  </body>
  </html>

Button toolbar

按钮工具栏可以通过组合一组按钮组来创建。使用实用程序类在组、按钮等之间添加一个空格。

Example

您可以使用*编辑和运行*选项编辑并尝试运行此代码。

  <!DOCTYPE html>
  <html lang="en">
  <head>
    <title>Bootstrap - Button Groups</title>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/css/bootstrap.min.css" rel="stylesheet">
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/js/bootstrap.bundle.min.js"></script>
  </head>
  <body>
    <div class="btn-toolbar mt-2" role="toolbar" aria-label="Toolbar button groups">
      <div class="btn-group me-2" role="group" aria-label="toolbarButtonGroup1">
        <button type="button" class="btn btn-primary">Primary</button>
        <button type="button" class="btn btn-info">Info</button>
        <button type="button" class="btn btn-secondary">Secondary</button>
      </div>
      <div class="btn-group me-2" role="group" aria-label="toolbarButtonGroup2">
        <button type="button" class="btn btn-success">Success</button>
        <button type="button" class="btn btn-dark">Dark</button>

      </div>
      <div class="btn-group" role="group" aria-label="toolbarButtonGroup3">
        <button type="button" class="btn btn-warning">Warning</button>
      </div>
    </div>
  </body>
  </html>

在工具栏中组合输入组和按钮组。使用实用程序适当地设置空间。

Example

您可以使用*编辑和运行*选项编辑并尝试运行此代码。

  <!DOCTYPE html>
  <html lang="en">
  <head>
    <title>Bootstrap - Button Groups</title>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/css/bootstrap.min.css" rel="stylesheet">
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/js/bootstrap.bundle.min.js"></script>
  </head>
  <body>
    <div class="btn-toolbar mb-3" role="toolbar" aria-label="toolbarButtonGroup1">
      <div class="btn-group me-2" role="group" aria-label="toolbarButtonGroup2">
        <button type="button" class="btn btn-outline-primary">Primary</button>
        <button type="button" class="btn btn-outline-info">Info</button>
        <button type="button" class="btn btn-outline-secondary">secondary</button>
      </div>
      <div class="input-group">
        <div class="input-group-text" id="inputbtnGroup1">@</div>
        <input type="text" class="form-control" placeholder="Username" aria-label="toolbarButtonGroup3" aria-describedby="inputButtonGroup1">
      </div>
    </div>

    <div class="btn-toolbar justify-content-between" role="toolbar" aria-label="toolbarButtonGroup4">
      <div class="btn-group" role="group" aria-label="toolbarButtonGroup1">
        <button type="button" class="btn btn-outline-warning">Warning</button>
        <button type="button" class="btn btn-outline-success">Success</button>
      </div>
      <div class="input-group">
        <input type="text" class="form-control" placeholder="tutorialspoint" aria-label="toolbarButtonGroup5" aria-describedby="inputButtonGroup2">
        <div class="input-group-text" id="inputbtnGroup2">@example.com</div>
      </div>
    </div>
  </body>
  </html>

Sizing

在嵌套多个组时，在每个 .btn-group 上使用 .btn-group- 而非每个按钮的按钮尺寸类。

Example

您可以使用*编辑和运行*选项编辑并尝试运行此代码。

  <!DOCTYPE html>
  <html lang="en">
  <head>
    <title>Bootstrap - Button Groups</title>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/css/bootstrap.min.css" rel="stylesheet">
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/js/bootstrap.bundle.min.js"></script>
  </head>
  <body>
    <h6 class="mt-4">Default size button group</h6>
    <div class="btn-group" role="group" aria-label="Default size button group">
      <button type="button" class="btn btn-outline-dark">Dark</button>
      <button type="button" class="btn btn-outline-warning">Warning</button>
    </div>

    <h6 class="mt-4">Small size button group</h6>
    <div class="btn-group btn-group-sm" role="group" aria-label="Small size button group">
      <button type="button" class="btn btn-outline-secondary">Secondary</button>
      <button type="button" class="btn btn-outline-success">Success</button>
    </div>

    <h6 class="mt-4">Large size button group</h6>
    <div class="btn-group btn-group-lg" role="group" aria-label="Large size button group">
      <button type="button" class="btn btn-outline-primary">Primary</button>
      <button type="button" class="btn btn-outline-info">Info</button>
    </div>

  </body>
  </html>

Nesting

要将下拉菜单与按钮序列混合，请在另一个 .btn-group 中使用 .btn-group 。

Example

您可以使用*编辑和运行*选项编辑并尝试运行此代码。

  <!DOCTYPE html>
  <html lang="en">
  <head>
    <title>Bootstrap - Button Groups</title>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/css/bootstrap.min.css" rel="stylesheet">
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/js/bootstrap.bundle.min.js"></script>
  </head>
  <body>
    <div class="btn-group mt-2" role="group" aria-label="Nested dropdown">
      <button type="button" class="btn btn-primary">Submit</button>
      <button type="button" class="btn btn-warning">Cancel</button>

      <div class="btn-group" role="group">
        <button type="button" class="btn btn-info dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
          Languages
        </button>
        <ul class="dropdown-menu">
          <li><a class="dropdown-item" href="#">English</a></li>
          <li><a class="dropdown-item" href="#">Hindi</a></li>
        </ul>
      </div>
    </div>
  </body>
  </html>

Vertical variation

要创建垂直堆叠的按钮组，请使用 .btn-group-vertical 类。在这种情况下，Bootstrap 不支持拆分按钮下拉菜单。

Example

您可以使用*编辑和运行*选项编辑并尝试运行此代码。

  <!DOCTYPE html>
  <html lang="en">
  <head>
    <title>Bootstrap - Button Groups</title>
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/css/bootstrap.min.css" rel="stylesheet">
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha3/dist/js/bootstrap.bundle.min.js"></script>
  </head>
  <body>
    <div class="btn-group-vertical mt-2" role="group" aria-label="Button group with verical variation">
      <button type="button" class="btn btn-primary">Primary</button>
      <button type="button" class="btn btn-warning">Warning</button>
      <button type="button" class="btn btn-info">Info</button>
    </div>
  </body>
  </html>

使用 dropdown menu 创建垂直按钮组。

  </head>
  <body>
    <div class="btn-group-vertical mt-2" role="group" aria-label="Vertical button group">
      <button type="button" class="btn btn-primary">Primary</button>
      <button type="button" class="btn btn-info">Secondary</button>
      <div class="btn-group" role="group">
        <button type="button" class="btn btn-warning dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
          Languages
        </button>
        <ul class="dropdown-menu">
          <li><a class="dropdown-item" href="#">English</a></li>
          <li><a class="dropdown-item" href="#">French</a></li>
        </ul>
      </div>
      <button type="button" class="btn btn-success">Success</button>
      </div>
    </div>
  </body>
  </html>

使用 radio buttons 创建垂直按钮组。
