vue实现弹幕功能

（1）效果

如上图所示的效果，这里我们使用vue 制作。

(2)使用技术 vue + vue-baberrage

1.安装：

 npm install vue-baberrage

2.引入

方式一：

import Vue from 'vue'
import { vueBaberrage } from 'vue-baberrage'
Vue.use(vueBaberrage)

方式二：

const vueBaberrage = request('vue-baberrage').vueBaberrage

方式三：

<script src="./dist/vue-baberrage.js"></script>

3.使用

HTML

<div id="app">
<vue-baberrage
   :isShow= "barrageIsShow"
   :barrageList = "barrageList"
   :loop = "barrageLoop"
   >
  </vue-baberrage>
</div>

JS

import { MESSAGE_TYPE } from 'vue-baberrage'

export default {
 name: 'app',
 data () {
  return {
   msg: 'Hello vue-baberrage',
   barrageIsShow: true,
   currentId : 0,
   barrageLoop: false,
   barrageList: []
  }
 },
 methods:{
  addToList (){
   this.barrageList.push({
    id: ++this.currentId,
    avatar: "./static/avatar.jpg",
    msg: this.msg,
    time: 5,
    type: MESSAGE_TYPE.NORMAL,
   });
 ...

(3)实例演示

这个封装成一个 vue的组件：

<template>
 <div class="barrages-drop">
  <vue-baberrage
   :isShow="barrageIsShow"
   :barrageList="barrageList"
   :maxWordCount="maxWordCount"
   :throttleGap="throttleGap"
   :loop="barrageLoop"
   :boxHeight="boxHeight"
   :messageHeight="messageHeight"
  >
  </vue-baberrage>
 </div>
</template>
<script>
import Vue from 'vue';
import { vueBaberrage, MESSAGE_TYPE } from 'vue-baberrage';
Vue.use(vueBaberrage);
export default {
 name: 'Barrages',
 data() {
 return {
  msg: '马优晨就是个辣鸡~',
  barrageIsShow: true,
  messageHeight: 3,
  boxHeight: 150,
  barrageLoop: true,
  maxWordCount: 3,
  throttleGap: 5000,
  barrageList: []
 };
 },
 mounted() {
 this.addToList();
 },
 methods: {
 addToList() {
  let list = [
  {
   id: 1,

   barrageStyle: 'red'
  },
