效果:

step:
1、components文件夹下新建MyConfirm文件夹,分别新建index.vue和index.js
index.vue:
<template> <van-popup v-model="isShow"> <div class="con_box"> <h3>{{text.title}}</h3> <p>{{text.message}}</p> <div class="btn"> <span @click="handleClose()" v-if="text.btn.cancelText">{{text.btn.cancelText}}</span> <span @click="handleOk()" v-if="text.btn.okText">{{text.btn.okText}}</span> </div> </div> </van-popup> </template> <script> export default { data() { return { isShow: true, text: { title: ‘提示‘, message: ‘确定删除此条信息?‘, btn: { okText: ‘确定‘, cancelText: ‘取消‘ } } } }, methods: { handleClose() { console.log(‘关闭‘) }, handleOk() { console.log(‘确定‘) } } } </script> <style lang=‘less‘ scoped> .van-popup { border-radius: 10px; .con_box { width: 270px; line-height: 1; text-align: center; color: #4d5c82; padding: 15px; box-sizing: border-box; > h3 { font-size: 20px; margin-top: 10px; margin-bottom: 20px; } > p { font-size: 17px; margin-bottom: 30px; } .btn { display: flex; justify-content: space-between; > span { display: block; width: 114px; background-color: #e0e5f5; text-align: center; line-height: 44px; font-size: 17px; } > span:last-of-type { background-color: #1288fe; color: #ffffff; } } } } </style>
index.js:
import Vue from ‘vue‘
import confirm from ‘./index.vue‘
let confirmConstructor = Vue.extend(confirm)
let myConfirm = function (text) {
  return new Promise((resolve, reject) => {
    let confirmDom = new confirmConstructor({
      el: document.createElement(‘div‘)
    })
    document.body.appendChild(confirmDom.$el) // new一个对象,然后插入body里面
    confirmDom.text = text // 为了使confirm的扩展性更强,这个采用对象的方式传入,所有的字段都可以根据需求自定义
    confirmDom.handleOk = function () {
      resolve()
      confirmDom.isShow = false
    }
    confirmDom.handleClose = function () {
      reject()
      confirmDom.isShow = false
    }
  })
}
export default myConfirm
2、main.js中引入并注册
// 引入自定义的 confirm 弹框
import myConfirm from ‘./components/MyConfirm/index.js‘
Vue.prototype.$confirm = myConfirm
3、使用
      this.$confirm({
        title: ‘提示‘,
        message: ‘确认删除此篇周计划吗?‘,
        btn: {
          okText: ‘确定‘,
          cancelText: ‘取消‘
        }
      })
        .then(() => {
      // do something
        })
        .catch(() => {
          console.log(‘no‘)
        })
