组件拆分出去后如何进行表单验证

 父组件
 <component
        :maintainStatus="maintainStatus"
        :maintainTitle="maintainTitle"
        :maintainCodeIpt="maintainCodeIpt"  //如何进行表单验证
        :maintainNameIpt="maintainNameIpt"  //如何进行表单验证
        @confirmEvent="confirmEvent"
        @cancelEvent="cancelEvent"
    >

</component>
    
子组件：
<template>
<div>
    <Modal
            :value="maintainStatus"
            :title="maintainTitle"
            :maskClosable="false"
    >
        <Form :label-width="110" ref="formValidate" :model="formValidate" :rules="ruleValidate" :show-message="false">
            <Row>
                <Col span="24">
                    <FormItem label="编码：" prop="maintainCodeIpt" class="formItemMargin">
                        <Input type="text" v-model="formValidate.maintainCodeIpt" placeholder="请输入编码"/>
                    </FormItem>
                </Col>
            </Row>
            <Row>
                <Col span="24">
                    <FormItem label="名称：" prop="maintainNameIpt" class="formItemMargin">
                        <Input type="text" v-model="formValidate.maintainNameIpt" placeholder="请输入名称"/>
                    </FormItem>
                </Col>
            </Row>
        </Form>
        <Row slot="footer" type="flex" justify="end">
            <Col>
                <Button type="success" @click="confirmEvent">确认</Button>
                <Button class="cancelButton" @click="cancelEvent">取消</Button>
            </Col>
        </Row>
    </Modal>
</div>

</template>
<script>
