vue项目中使用this.$confirm解析

 <template slot-scope="scope">
            <el-button size="mini" @click="handleEdit(scope.$index, scope.row)"
              >编辑</el-button
            >
            <el-button
              size="mini"
              type="danger"
              @click="handleDelete(scope.$index, scope.row)"
              >删除</el-button
            >
          </template>

 handleDelete(index, item) {
      this.$confirm("你确定要删除吗，请三思,后果自负", {
        confirmButtonText: "确定",
        cancelButtonText: "取消",
        type: "warning",
      })
        .then(() => {
          console.log("确定了，要删除");
        })
        .catch(() => {
          console.log("放弃了");
        });
    },

import {MessageBox} from 'element-ui';

//Vue.use(MessageBox);//与其他引用不同的是，这里“不能”加Vue.use(MessageBox),不然会出现问题，达不到想要的效果
Vue.prototype.$confirm = MessageBox.confirm;

import {MessageBox} from ‘element-ui'

Vue.prototype.$confirm = MessageBox.confirm

<template>
  <div>
    <el-button type="text" @click="dialogVisible = true">点击打开 Dialog</el-button>
