1.在xxx.vue文件的script标签中引入

import { MessageBox } from 'mint-ui'

2.使用

  methods: {
    download () {
      MessageBox({
        title: '确定下载附件？',
        message: '附件名称?',
        showCancelButton: true
      }).then(action => {
        if (action === 'confirm') {
          console.log(1)
        }
        if (action === 'cancel') {
          console.log(2)
        }
      }).catch(err => {
        console.log(err)
      })
    }
  }
