还是自己来解决吧：总共三个文件：ConfirmAlert.js
import Vue from 'vue';
import confirm from '../components/ConfirmAlert.vue';
let confirmConstructor = Vue.extend(confirm);
let theConfirm = function (text) {
return new Promise((res, rej) =>
{
//promise封装，ok执行resolve，no执行rejectlet
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.ok = function () {
res()
confirmDom.isShow = false
}
confirmDom.close = function () {
rej()
confirmDom.isShow = false
} })
}
export default theConfirm;

在项目的主入口的JS文件中加入以下语句：main.js
import theConfirm from '@/pages/salary/data/ConfirmAlert.js'
Vue.prototype.$Alretconfirm = theConfirm;

在页面中调用：
页面的按钮事件：
this.$Alretconfirm({
type: '提示',
msg:'是否删除这条信息？'
btn: {
ok: '确定', no: '取消'
},
layerNum: 1,
//msgDetail: ''
}).then(() => {
// 确认
// do something
}).catch(() => {
//取消
})
