"htmlcode">

<template>
  <div v-show="visible" class="model-container">
   <div class="custom-confirm">
    <div class="custom-confirm-header">{{ title }}</div>
    <div class="custom-confirm-body" v-html="content"></div>
    <div class="custom-confirm-footer">
     <Button @click="handleOk">{{ okText }}</Button>
     <Button @click="handleCancel">{{ cancelText }}</Button>
    </div>
   </div>
  </div>
</template>
<script lang="ts">
import { defineComponent, watch, reactive, onMounted, onUnmounted, toRefs } from "vue";
export default defineComponent({
 name: "ElMessage",
 props: {
  title: {
   type: String,
   default: "",
  },
  content: {
   type: String,
   default: "",
  },
  okText: {
   type: String,
   default: "确定",
  },
  cancelText: {
   type: String,
   default: "取消",
  },
  ok: {
   type: Function,
  },
  cancel: {
   type: Function,
  },
 },
 setup(props, context) {
  const state = reactive({
   visible: false,
  });
  function handleCancel() {
   state.visible = false;
   props.cancel && props.cancel();
  }
  function handleOk() {
   state.visible = false;
   props.ok && props.ok();
  }
  return {
   ...toRefs(state),
   handleOk,
   handleCancel,
  };
 },
});
</script>

2、插件注册

"htmlcode">

import { createVNode, render } from 'vue';
import type {App} from "vue";
import MessageConstructor from './index.vue'
const body=document.body;
const Message: any= function(options:any){
 const modelDom=body.querySelector(`.container_message`)
  if(modelDom){
   body.removeChild(modelDom)
  }
  options.visible=true;
  const container = document.createElement('div')
  container.className = `container_message`
  //创建虚拟节点
  const vm = createVNode(
   MessageConstructor,
   options,
  )
  //渲染虚拟节点
  render(vm, container)
  document.body.appendChild(container);
} 
export default {
  //组件祖册
  install(app: App): void {
    app.config.globalProperties.$message = Message
  }
}
