怎么在这个输入框内加个默认值“ <input type="text" name="sjId" lay-verify="required" placeholder="商家id" class="layui-input">”

要在HTML输入框中添加默认值,你可以直接在`<input>`标签的`placeholder`属性中设置。对于你给出的代码示例,要在`name="sjId"`的文本输入框中设置默认值为"商家id",你应该这样写:
```html
<input type="text" name="sjId" lay-verify="required" placeholder="商家id" value="商家id" class="layui-input">
```
这里`value`属性用于设定输入框的初始显示内容,即使用户没有手动输入,也会显示这个默认值。如果`lay-verify="required"`是用来验证必填项的话,那么默认值应该让用户知道该字段需要填写。

可以通过修改CSS样式来调整label的宽度为200,代码如下:
```
<style>
.layui-form-label {
width: 200px;
}
</style>
```
将上述代码放在HTML代码之前或者在外部CSS文件中即可。
<div class='layui-form-item'> <label class='layui-form-label'>各分项数量<span class="required-field"></span></label> <div class='layui-input-block'> <div class='layui-inline'> <input type='text' name='vcFxsl1' id='vcFxsl1' placeholder='请输入分项数量1' class='layui-input' lay-verify='required' maxlength="8" /> </div> <div class='layui-inline'> <input type='text' name='vcFxsl2' id='vcFxsl2' placeholder='请输入分项数量2' class='layui-input' lay-verify='required' maxlength="8" /> </div> <div class='layui-inline'> <input type='text' name='vcFxsl3' id='vcFxsl3' placeholder='请输入分项数量3' class='layui-input' lay-verify='required' maxlength="8" /> </div> </div> </div> 把三个输入框修改为 上下箭头选择数字 0-99
你可以使用`layui`的下拉选择框来替换文本输入框,让用户从上下箭头中选择数字0-99。下面是修改后的代码示例:
```html
<div class='layui-form-item'>
<label class='layui-form-label'>各分项数量<span class="required-field"></span></label>
<div class='layui-input-block'>
<div class='layui-inline'>
<select name='vcFxsl1' id='vcFxsl1' lay-verify='required'>
<option value=''>请选择分项数量1</option>
<!-- 生成数字选项 -->
<option value='0'>0</option>
<option value='1'>1</option>
<!-- 依此类推,生成99个选项 -->
<option value='99'>99</option>
</select>
</div>
<div class='layui-inline'>
<select name='vcFxsl2' id='vcFxsl2' lay-verify='required'>
<option value=''>请选择分项数量2</option>
<!-- 生成数字选项 -->
<option value='0'>0</option>
<option value='1'>1</option>
<!-- 依此类推,生成99个选项 -->
<option value='99'>99</option>
</select>
</div>
<div class='layui-inline'>
<select name='vcFxsl3' id='vcFxsl3' lay-verify='required'>
<option value=''>请选择分项数量3</option>
<!-- 生成数字选项 -->
<option value='0'>0</option>
<option value='1'>1</option>
<!-- 依此类推,生成99个选项 -->
<option value='99'>99</option>
</select>
</div>
</div>
</div>
```
这样,用户就可以从下拉选择框中选择数字0-99作为各分项的数量。记得根据实际需求修改每个下拉选择框的`name`和`id`属性。
