		<component v-if="options.component" :is="options.component" v-bind="options.props" v-on="options.events" ref="modalessComponent" ></component>
	</div>
</template>

<script>
	import Bus from "./bus.js";
	export default {

　　bus.js

let instance = null;

class EventBus {
    constructor() {
        if (!instance) {
            this.events = {};
            instance = this;
        }
        return instance;
    }

    $emit(event, message) {
        if (!this.events[event])
            return;

        const callbacks = this.events[event];

        for (let i = 0, l = callbacks.length; i < l; i++) {
            const callback = callbacks[i];

            callback.call(this, message);
        }
    }

    $on(event, callback) {
        if (!this.events[event])
            this.events[event] = [];

        this.events[event].push(callback);
    }
}

export default new EventBus();

　　index.js

import Bus from './bus';
import Component from './component.vue';

export default {
    install(Vue) {
        // Global $vuedals property
        Vue.prototype.$vuedals = new Vue({
            name: '$vuedals',

            created() {
               
            },
            methods: {
                open(options = null) {
                    Bus.$emit('open', options);
                },

                close(data = null) {
                    Bus.$emit('close', data);
                }
 
            }
        });

        Vue.component('vuedals', Component);

    }
};

　　使用：

一、引入

import vuedals from './components/vuedals'

Vue.use(vuedals);

 

二、调用

 

import box from '../components/box.vue';




this.$vuedals.open({
    	 		component:box, //引入的模板文件
    	 		props:{title:"这是一个title"},
    	 		events:{
    	 			myEvent:function(){
    	 				console.log("myEvent....")
    	 			}
    	 		}
    	 })

　　

其中box.vue为

<template>
	<div class="box">
		这里是弹出层的内容
		<p>{{title}}</p>
		<li @click="myEvent">点击我</li>
		<li @click="close">关闭弹出层</li>
	</div>
</template>

<script>
export default {
	  name: 'box',
	  data () {
	    return {
	      msg: ''
	    };
	  },
	  props:["title"],
	  methods: {
	   myEvent:function(){
	      this.$emit("myEvent",{});	
	   },
	   close:function(){
	   
	   	console.log(this.$vuedals.close())
	   }
	  }
};
</script>

<style>
	.box{
		margin: 40% auto 0;
		width: 80%;
		height: 200px;
		background: #fff;
		border-radius: 10px;
	}
</style>

　　效果：
