vue.extend实现alert模态框弹窗组件

本文通过Vue.extend创建组件构造器的方法写弹窗组件，供大家参考，具体内容如下

alert.js文件代码

import Vue from 'vue'
// 创建组件构造器
const alertHonor = Vue.extend(require('./alert.vue'));
var currentMsg = {callback:function(){
}}
export default function(options){
  var alertComponent = new alertHonor({el: document.createElement('div')});
  alertComponent.title = options.title;
  alertComponent.ranking = options.ranking;
  // 把alertHonor.vue加入body中
  alertComponent.$appendTo(document.body);
  // 回调函数
  alertComponent.callback = function(action) {
    if (action == 'share') {
      options.share();
    }
  };
}

alert.vue代码

<template>
  <div class="alertHonor" v-if="showAlertHonor">
    <div class="alertHonorBox" @click="alertHonorClick"></div>
    <div class="honorWindow">
      <div class="honorClose" @click="honorClose"></div>
      <div class="honorBg">
        <div class="honorShare">
          <div class="honorBgLeft">升级通知</div>
          <div class="honorBgRight" @click='handleActions("share")'>分享</div>
        </div>
        <div class="honorText">{{title}}</div>
      </div>
      <div class="honorRanking">
        {{ranking}}
      </div>
    </div>
  </div>
</template>
<script>
  export default{
    props:{
      img:{type:String},  //图片
      title:{type:String},  //达人昵称
      ranking:{type:String},   //排名
      share:{type:Function}, //分享
    },
    data(){
      return{
        showAlertHonor:true
      }
    },
    methods:{
      alertHonorClick(){ //点击其他区域
        this.showAlertHonor = false; //关闭整个窗口
      },
      honorClose(){ //点击关闭图标
        this.showAlertHonor = false;
      },
      handleActions(action){
        this.callback(action);
      }
    }
  }
</script>

  export default{
    data(){
      return{

      }

    ready(){
    },
    methods:{
      back(){
        alert(1)
      },
      submit(){
        var vm = this;
        AlertHonor({
          title:'拜访达人',
          ranking:'您在全国排名第99',
          share: function(){
            vm.share();
          }
        });
