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，好哒"
        },
        // ... ...
    ]
});
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:"在吗？"},
            {info:"不在"},
            {info:"你把草稿交了没有"},
            {info:"我今天中午吃完饭   就一直看剧了"},
            {info:"我发现我真的是宅女"},
            {info:"哈哈哈"},
            {info:"有空找你约顿饭"},
            {info:"嗯嗯"},
            {info:"反正影响不大"}
        ]
    }
}
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
    }
  ]
})

// 解决路由报错的代码
const originalPush = Router.prototype.push
Router.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)" class="chatuser" 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)";
      // 动态dom元素渲染完成之后，跳转到另一个界面（ChatDetail）
      // 获取动态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>

父组件使用子组件里的属性和方法：
在父组件中的子组件上定义ref属性，通过 this.$ refs.name.属性或this.$refs.name.方法

ChatChild.vue：

<template>
  <div id="chatchild">
    <div class="photo">
      <img :src="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 {

        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;
