要解决这个问题，有两种方法。注意：您可以使用任何您喜欢的日期选择器。第一个：
<Field
name="start_date"
:class="{'is-invalid': errors.start_date}"
v-slot="{ field }"
class="form-control"
>
<el-date-picker
v-bind="field"
type="date"
placeholder="Pick a day"
size="default"
/>
</Field><Form @submit="onSubmit" :validation-schema="schema" v-slot="{errors, values}">
<Field
name="end_date"
:class="{'is-invalid': errors.end_date}"
class="form-control"
type="date"
>
</Field>
</Form>有关更多信息，请查看vee验证文档。以下是链接：https://vee-validate.logaretm.com/v4/api/field/
