<!--方式1-->
<template>
  <button  @click="show_open">打開彈窗</button>
  <conform ref="conform_ref"></conform>
</template>

<script >

    // template中使用但是一定要返回，否則會(huì)出問題
    return{conform_ref, show_open}
  }
}

</script>


<!--方式二-->
<!--<template>-->
<!--  <button  @click="validate_ref">主要按鈕</button>-->
<!--  <conform ref="validate" ></conform>-->

<!--</template>-->

<!--<script setup>-->
<!--import conform from './components/conform.vue'-->

<!--const validate_ref = ()=>{-->
<!--  validate.value.open()-->
