-
<button>
在<form>
中默认为type="submit"
,因此要力求具体,并且始终包含一个type
。 - 您可以使用
<form>
上的disabled
属性禁用表单中的每个表单元素。
由于Bootstrap将 display: block
和 width: 100%
应用于我们的几乎所有表单控件,因此表单默认情况下将垂直堆叠。可以使用其他类在每个窗体的基础上更改此布局。
您可以随意使用 <fieldset>
、 <div>
或几乎任何其他元素来构建表单。
<div class="mb-3">
<label for="formGroupExampleInput" class="form-label">Example label</label>
<input type="text" class="form-control" id="formGroupExampleInput" placeholder="Example input placeholder">
</div>
<div class="mb-3">
<label for="formGroupExampleInput2" class="form-label">Another label</label>
<input type="text" class="form-control" id="formGroupExampleInput2" placeholder="Another input placeholder">
</div>
<div class="row">
<div class="col">
<input type="text" class="form-control" placeholder="First name" aria-label="First name">
</div>
<div class="col">
<input type="text" class="form-control" placeholder="Last name" aria-label="Last name">
</div>
</div>
<div class="row g-3">
<div class="col">
<input type="text" class="form-control" placeholder="First name" aria-label="First name">
</div>
<div class="col">
<input type="text" class="form-control" placeholder="Last name" aria-label="Last name">
</div>
</div>
网格系统也可以创建更复杂的布局。
