Bootstrap 表单输入 (更多)

静态控件

如果需要在水平表单中的表单标签旁边插入 纯文本，请在 <p> 元素上使用 .form-control-static 类:

实例

<form class="form-horizontal">
  <div class="form-group">
    <label class="control-label col-sm-2">Email:</label>
    <div class="col-sm-10">
      <p class="form-control-static">someone@example.com</p>
    </div>
  </div>
</form>

Bootstrap 输入组

.input-group 类是一个容器，通过在其前面或后面添加图标、文本或按钮作为 "帮助文本" 来增强输入。

.input-group-addon 类在输入字段旁边附加一个图标或帮助文本。

实例

<form>
  <div class="input-group">
    <span class="input-group-addon"><i class="glyphicon glyphicon-user"></i></span>
    <input id="email" type="text" class="form-control" name="email" placeholder="Email">
  </div>
  <div class="input-group">
    <span class="input-group-addon"><i class="glyphicon glyphicon-lock"></i></span>
    <input id="password" type="password" class="form-control" name="password" placeholder="Password">
  </div>
  <div class="input-group">
    <span class="input-group-addon">Text</span>
    <input id="msg" type="text" class="form-control" name="msg" placeholder="Additional Info">
  </div>
</form>

.input-group-btn 在输入旁边附加一个按钮。它搜索栏一起使用:

实例

<form>
  <div class="input-group">
    <input type="text" class="form-control" placeholder="Search">
    <div class="input-group-btn">
      <button class="btn btn-default" type="submit">
        <i class="glyphicon glyphicon-search"></i>
      </button>
    </div>
  </div>
</form>

Bootstrap 表单控件状态

• 聚焦 input - 被聚焦的输入框边框增加阴影效果
• 禁用 input - 添加 disabled 属性以禁用输入框
• 禁用 fieldset - 给 fieldset 元素添加 disabled 属性来禁用里面的所有控件
• 只读 input - 向输入添加 readonly 只读属性以防止用户输入
• 验证状态 - Bootstrap 包含了 error（错误）, warning（警告）, 和 success（成功）的验证样式, 需要向其父元素添加 .has-warning, .has-error, 或者 .has-success
• 图标 - 您可以使用 has-feedback 类和图标来添加反馈图标
• 隐藏标签 - 添加 .sr-only 来隐藏标签
