本文實例為大家分享了Vue實現聊天界面展示的具體代碼，供大家參考，具體內容如下

1.功能需求

根據索引選擇跟不同的人進行聊天

2.代碼展示

mock.js：

import Mock from ’mockjs’Mock.mock('/chatchild',{ ’result’:[{ id:'001', imgurl:'/static/image/10.jpg', name:'XKDK', date:'09:23', words:'哈哈，好噠'},// ... ... ]});export default Mock

userinfo.js：

let usermsg={ id:'122', imgurl:'/static/image/8.jpg', words:'是的！', data:{id:'1529',imgurl:'/static/image/7.jpg',name:'易安居士',words:[ {info:'在嗎？'}, {info:'不在'}, {info:'你把草稿交了沒有'}, {info:'我今天中午吃完飯 就一直看劇了'}, {info:'我發現我真的是宅女'}, {info:'哈哈哈'}, {info:'有空找你約頓飯'}, {info:'嗯嗯'}, {info:'反正影響不大'}] }}export default usermsg

index.js：

import Vue from ’vue’import Router from ’vue-router’import Chat from ’../components/Chat.vue’import ChatDetail from ’../components/Pages/ChatDetail.vue’Vue.use(Router)export default new Router({ routes: [ { path: ’/Chat ’, component: Chat }, { path:’/ChatDetail’, component:ChatDetail } ]})// 解決路由報錯的代碼const originalPush = Router.prototype.pushRouter.prototype.push = function push(location) { return originalPush.call(this, location).catch(err => err)}

Chat.vue：

<template> <div id='chat'> <Bottom /> <Header :name='msg' /> <div class='chat_alluser'> <div ref='chatuser' @click='checkChild(index)' v-for='(item,index) in chat' :key='index'><ChatChild :imgsrc='item.imgurl' :nickname='item.name' :time='item.date' :word='item.words' /> </div> </div> </div></template><script>import Bottom from '../components/Menu/Bottom';import Header from '../components/Menu/Header';import ChatChild from '../components/Pages/ChatChild';export default { name: 'Chat', components: { Bottom: Bottom, Header: Header, ChatChild: ChatChild }, data() { return { msg: '微信', chat: null, name: null }; }, mounted() { this.$axios.get('/chatchild').then(res => { this.chat = res.data.result; }); }, methods: { checkChild(index) { this.$refs.chatuser[index].style.backgroundColor = 'rgb(240,240,240)'; // 動態dom元素渲染完成之后，跳轉到另一個界面（ChatDetail） // 獲取動態name let username = this.chat[index].name; this.$nextTick(() => {this.$router.push({ path: '/ChatDetail', query: { name: username }}); }); } }};</script><style lang='scss' scope>#chat { width: 100%; .chat_alluser { margin-bottom: 7.5rem; .chatuser { position: relative; top: 3.5rem; padding: 0.3rem 0; } }}</style>

父組件使用子組件里的屬性和方法：在父組件中的子組件上定義ref屬性，通過 this.$ refs.name.屬性或this.$refs.name.方法

ChatChild.vue：

<template> <div id='chatchild'> <div class='photo'> <img :src='http://www.gepszalag.com/bcjs/imgsrc' alt /> </div> <div class='content'> <div> <span class='content_nickname'>{{nickname}}</span> <span class='content_time'>{{time}}</span> </div> <span class='content_word'>{{word}}</span> </div> </div></template><script>export default { name: 'ChatChild', props:{ ’imgsrc’:String, ’nickname’:String, ’time’:String, ’word’:String }};</script><style lang='scss' scope>#chatchild { width: 100%; height: 5rem; display: flex; flex-direction: row; box-sizing: border-box; .photo { flex: 1; height: 5rem; img{object-fit: cover;width: 4rem;height: 4rem;border-radius: 5px;display: block;margin: 0 auto;margin-top: 0.5rem;margin-left: 1rem; } } .content { flex: 4; height: 5rem; border-bottom: 0.5px solid rgb(240, 240, 240); padding-left: 0.5rem; padding-top: 0.5rem; box-sizing: border-box; div{ .content_nickname{display: inline-block;font-size: 1.1rem;margin-top: 0.3rem; } .content_time{float: right;margin-right: 1rem;color: rgb(209, 206, 206);font-size: 0.8rem; } } .content_word{ color: rgb(209, 206, 206); font-size: 0.8rem; display: block; margin-top: 0.5rem; } }}</style>

ChatDetail.vue：
