复选框
<div class="form-check"> <input class="form-check-input" type="checkbox" value="" id="flexCheckDefault"> <label class="form-check-label" for="flexCheckDefault"> 默认的复选框 </label> </div> <div class="form-check"> <input class="form-check-input" type="checkbox" value="" id="flexCheckChecked" checked> <label class="form-check-label" for="flexCheckChecked"> 默认选中的复选框 </label> </div>
不确定的
当通过 JavaScript
手动设置复选框时,可以使用 :indeterminate
伪类(没有可用的 HTML 属性来指定它)。
<div class="form-check"> <input class="form-check-input" type="checkbox" value="" id="flexCheckIndeterminate"> <label class="form-check-label" for="flexCheckIndeterminate"> 不确定的复选框 </label> </div>
如果你正使用 jQuery,可以用下面方法:
$('#your-checkbox').prop('indeterminate', true)
禁用
添加 disabled
属性,关联的 <label>
会自动设置样式以匹配较浅的颜色,以帮助指示输入的状态。
<div class="form-check"> <input class="form-check-input" type="checkbox" value="" id="flexCheckDisabled" disabled> <label class="form-check-label" for="flexCheckDisabled"> 禁用复选框 </label> </div> <div class="form-check"> <input class="form-check-input" type="checkbox" value="" id="flexCheckCheckedDisabled" checked disabled> <label class="form-check-label" for="flexCheckCheckedDisabled"> 禁用选中的复选框 </label> </div>
默认(堆叠)
默认情况下,任何数量的直接同级复选框都将垂直堆叠并以 .form-check
适当间隔。
<div class="form-check"> <input class="form-check-input" type="checkbox" value="" id="defaultCheck1"> <label class="form-check-label" for="defaultCheck1"> 默认复选框 </label> </div> <div class="form-check"> <input class="form-check-input" type="checkbox" value="" id="defaultCheck2" disabled> <label class="form-check-label" for="defaultCheck2"> 禁用复选框 </label> </div>
内联的
通过将 .form-check-inline
添加到任何 .form-check
将复选框或复选框分组到同一水平行。
<div class="form-check form-check-inline"> <input class="form-check-input" type="checkbox" id="inlineCheckbox1" value="option1"> <label class="form-check-label" for="inlineRadio1">1</label> </div> <div class="form-check form-check-inline"> <input class="form-check-input" type="checkbox" id="inlineCheckbox2" value="option2"> <label class="form-check-label" for="inlineRadio2">2</label> </div> <div class="form-check form-check-inline"> <input class="form-check-input" type="checkbox" id="inlineCheckbox3" value="option3" disabled> <label class="form-check-label" for="inlineRadio3">3 (禁用)</label> </div>
不使用 label
<div> <input class="form-check-input" type="checkbox" id="checkboxNoLabel" value="" aria-label="..."> </div>
复选框切换按钮
<input type="checkbox" class="btn-check" id="btn-check" autocomplete="off"> <label class="btn btn-primary" for="btn-check">单切换</label> <input type="checkbox" class="btn-check" id="btn-check-2" checked autocomplete="off"> <label class="btn btn-primary" for="btn-check-2">选中</label> <input type="checkbox" class="btn-check" id="btn-check-3" autocomplete="off" disabled> <label class="btn btn-primary" for="btn-check-3">禁用</label>
边框样式
<input type="checkbox" class="btn-check" id="btn-check-outlined" autocomplete="off"> <label class="btn btn-outline-primary" for="btn-check-outlined">单切换</label> <input type="checkbox" class="btn-check" id="btn-check-2-outlined" checked autocomplete="off"> <label class="btn btn-outline-secondary" for="btn-check-2-outlined">选中</label>
