最初可运行代码

弹窗组件代码：

（后来发现以下代码可运行，但打包 typescript 类型检查出错，可打包的代码在文末）

<template><div v-if="isVisible" class="dialog"><div class="dialog-content"><div style="padding: 40px 40px; text-align: center">{{message}}</div><div style="display: flex; border-top: 1px solid #d2d0d0"><div @click="cancel" class="dialog-button">取消</div><div style="border-right: 1px solid #d2d0d0"></div><div @click="handleConfirm" class="dialog-button" style="color: #4e8fd3">确定</div></div></div></div>
</template><script setup lang="ts">
import { ref } from 'vue';const isVisible = ref(false);
const message = ref('');
const confirmCallback = ref(null)
const cancelCallback = ref(null);const showDialog = (params = {} ) => {isVisible.value = true;message.value = params.message || '提示内容';confirmCallback.value = params.confirmCallback || null;cancelCallback.value = params.cancelCallback || null;
};const handleConfirm = () => {if (confirmCallback.value) {confirmCallback.value();}isVisible.value = false;
};const cancel = () => {if (cancelCallback.value) {cancelCallback.value();}isVisible.value = false;
};defineExpose({showDialog
});
</script><style scoped>
.dialog {position: fixed;top: 0;left: 0;width: 100%;height: 100%;background-color: rgba(0, 0, 0, 0.5);display: flex;justify-content: center;align-items: center;font-size: 16px;
}.dialog-content {background-color: #fff;border-radius: 10px;width: 80%;
}.dialog-button {flex-grow: 1;text-align: center;padding: 20px 0;
}
</style>

效果：更适用于移动端

弹窗显示：

<template><div><button @click="openDialog">打开弹窗</button><ChildDialg ref="dialogRef" /></div>
</template><script setup lang="ts">
import { ref } from 'vue';// 1. 引入子组件
import ChildDialg from "@/views/components/ChildDialg.vue";// 2. 定义子组件 ref 参数
const dialogRef = ref(null);const openDialog = () => {// 3. 弹窗显示dialogRef.value.showDialog({message: '内容',confirCallback: () => {}});
};
</script>

打包 typescript 检查错误修复

######## 项目打包，typescript 类型检查报错 ###########

1. 函数接收类没有属性定义

2. 调用弹窗时未作 组件 非空判断

3. 接收的回调函数参数，定义的初始值为 null ，无法以函数方式调用

4. 定义的组件 ref 参数默认值为 null ，无法调用子组件暴露的函数

5. 子组件定义的参数 与 父组件传递的参数不一致（定义了取消回调，但没有传入）

可以选择传入“取消”操作的回调函数，但考虑到此组件在我实际运用时取消没有其它操作，便选择不定义其回调函数

最终可打包的代码

<template><div v-if="isVisible" class="dialog"><div class="dialog-content"><div style="padding: 40px 40px; text-align: center">{{message}}</div><div style="display: flex; border-top: 1px solid #d2d0d0"><div @click="cancel" class="dialog-button">取消</div><div style="border-right: 1px solid #d2d0d0"></div><div @click="handleConfirm" class="dialog-button" style="color: #4e8fd3">确定</div></div></div></div>
</template><script setup lang="ts">
