文件目录：

github地址：https://github.com/xingkongwuyu/vue-spa-experience/tree/master/src/components

最终的效果：

 组件的源码解析：

confirm ：  confirm的框架

./index.js

import confirmBox from './src/index';
export default {
    install(Vue) {
      Vue.prototype.$confirm = confirmBox;
    },
  };

使用transition来实现动画效果

<template>
<transition name="mei-modal-fade">
    <div v-show="show" class="mei-modal" tabindex="-1" role="dialog" aria-labelledby="bombConfirmLabel" aria-hidden="false">
        <div class="mei-modal-mask"></div>
        <div class="mei-modal-wrap">

引入全局 使用：

import VueConfirm from './components/confirm'

Vue.use(VueConfirm)

methods：{
  confirm () {
          var content = ` <div class="title">11111</div>`
          var vm=this
         const confirm = this.$confirm({
          title:'23232',
          text:content,
          dangerouslyUseHTMLString:true,
          button:[{
                text: '确定',
                ontap: function () {
                    confirm.close().then(function(res){
                     console.log(111233233231)
                   });
                }},
                {
                text: '取消',
                ontap: function () {
                  
                   confirm.close().then(function(res){
                       console.log('close')
                   });
                }
            }]
    
        });
     },
}

配置项：title ：标题

      dangerouslyUseHTMLString：内容是否是html；
      button：按钮
             text：按钮名称

             ontap：点击后的函数
