vue表单vxe-form如何多字段联动校验，对一个控件校验多个关联字段
<p>vue表单vxe-form如何多字段联动校验，对一个控件校验多个关联字段。正常的表单场景是一个控件一个字段，那么配置起来非常任意，一个字段对应一个校验规则。当时某些复杂场景就不一样了，比如用户控件，有id/code/role等。比如范围日期选择，一个控件是对应2个字段的，开始日期和结束日期。这个时候就可以使用 rule 规则中 field 属性来指定复杂的多字段校验。</p><p>https://vxetable.cn</p>
<h2 id="表单-日期范围-多字段校验">表单-日期范围-多字段校验</h2>
<p>举个例子，比如日期范围选择，有2个字段，先给控件绑定一个不存在的字段，然后在这个字段里面配置2条规则，分别校验多个字段；当某个字段为空时都能被直接校验并提示出来</p>
