使用 $refs
父组件
<template>
<section class="dataList">
<provincesDataList ref="provincesDataRef"/>
</section>
</template>
<script lang="ts" setup>
import provincesDataList from "../provincesDataList.vue";
const provincesDataRef = ref()
// 调用子组件getDataListFn方法
provincesDataRef.value.getDataListFn()
</script>
子组件:
<script lang="ts" setup>
import { ref, defineExpose } from "vue";
const getDataListFn = async () => {
// 方法体
}
defineExpose({
getDataListFn
});
</script>
