自定义提示确认弹窗-vue

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）

html 复制代码

<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">
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：

html 复制代码

<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 ###########

函数接收类没有属性定义

调用弹窗时未作组件非空判断

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

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

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
