vue封装可复用组件confirm,并绑定在vue原型上的示例

<template>
 <div class="confirm" v-if="isShow">
  <div class="con_box" >
   <div class="context">
    <h7>{{text.type}}</h7>
    <p>{{text.msg}}</p>
    <div class="btn">
     <span @click="close()" v-if="text.btn.no">{{text.btn.no}}</span>
     <span @click="ok()" v-if="text.btn.ok">{{text.btn.ok}}</span>
    </div>
   </div>
  </div>
 </div>
</template>
<script>
export default {
 data(){
  return{
   isShow:true,
   text:{
    type:'提示',    
    msg:'确定删除此条信息？',
    btn:{
     ok:'确定',
     no:'取消'
    },
   }
  }
 },
 methods:{
  close(){
   console.log('关闭');
  },
  ok(){
   console.log('确定')
  }
 }
}
</script>
<style scoped>

import Vue from 'vue';

let confirmConstructor = Vue.extend(confirm);

let theConfirm = function (text) {

  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; 
 
 //暴露出去，别忘记挂载到vue的原型上 
 // => 在main.js里面先引入 import theConfirm from './components/confirm/confirm.js'
 // => 再挂载 Vue.prototype.$confirm = theConfirm;
 //在需要的地方直接用以下方法调用即可：
 // this.$confirm({
 //  type:'提示',
 //  msg:'是否删除这条信息？',
 //  btn:{
 //   ok:'yes',
 //   no:'no'
 //  }
 // }).then(() => {
 //  console.log('ok')
 // })
 // .catch(() => {
 //  console.log('no')
 // })

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'

//这里就是对组件的绑定
