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。
表单-日期范围-多字段校验
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
<template>
<div>
<vxe-form v-bind="formOptions" v-on="formEvents" ></vxe-form>
</div></template><script setup>import { reactive } from 'vue'import { VxeUI } from 'vxe-pc-ui'const formOptions = reactive({ titleWidth: 120, data: { name: 'test1', startDate: '', endDate: ''
}, rules: { _startAndEnd: [
{ field: 'startDate', required: true, message: '请选择开始时间' },
{ field: 'endDate', required: true, message: '请选择结束时间' }
]
}, items: [
{ field: 'name', title: '名称', span: 24, itemRender: { name: 'VxeInput' } },
{ field: '_startAndEnd', title: '2个字段格式', span: 24, itemRender: { name: 'VxeDateRangePicker', startField: 'startDate', endField: 'endDate' } },
{ align: 'center', span: 24, itemRender: { name: 'VxeButtonGroup', options: [
{ type: 'submit', content: '提交', status: 'primary' },
{ type: 'reset', content: '重置' }
]
}
}
]
})const formEvents = {
submit () { VxeUI.modal.message({ content: '保存成功', status: 'success' })
},
reset () { VxeUI.modal.message({ content: '重置事件', status: 'info' })
}
}</script>表格-日期范围-多字段校验
同样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
<template>
<div>
<vxe-button @click="fullValidEvent">校验全量数据</vxe-button>
<vxe-grid ref="gridRef" v-bind="gridOptions"></vxe-grid>
</div></template><script setup>import { ref, reactive } from 'vue'import { VxeUI } from 'vxe-table'const gridRef = ref()const gridOptions = reactive({ border: true, showOverflow: true, keepSource: true, height: 300, editConfig: { trigger: 'click', mode: 'row', showStatus: true
}, editRules: { _startAndEnd: [
{ field: 'startDate', required: true, message: '请选择开始时间' },
{ field: 'endDate', required: true, message: '请选择结束时间' }
]
}, columns: [
{ type: 'checkbox', width: 60 },
{ type: 'seq', width: 70 },
{ field: 'name', title: 'Name', editRender: { name: 'VxeInput' } },

], data: [

]
})const fullValidEvent = async () => { const $grid = gridRef.value
if ($grid) { const errMap = await $grid.validate(true) if (errMap) { VxeUI.modal.message({ status: 'error', content: '校验不通过！' })
} else { VxeUI.modal.message({ status: 'success', content: '校验成功！' })
}
}
