Vue列表如何实现滚动到指定位置样式改变效果

<GeminiScrollbar
       class="my-scroll-bars">
      <li v-for="(item,index) in hrs" :id="index"
       :key="index"
       :class="{ active: currentSession"
       @click="changeCurrentSession(item)">
       <img class="avatar"
         :src="/UploadFiles/2021-04-02/item.userface">

搜索框：这里使用带提示的输入框，


<el-autocomplete
       v-model="SearchHr" class="input-with-select" popper-append-to-body="false"
       style="width: 90%;padding-left: 5%;padding-top: 10px;margin-bottom: 10px"
       size="small"
       :fetch-suggestions="querySearch"
       placeholder="请输入内容"
       @select="handleSelect"
     >
      <el-button slot="append" icon="el-icon-search"
         @click="SearchCurrentSession(SearchHr)"></el-button>
     </el-autocomplete>


JS代码：请求为get请求的axios封装，hr为查询返回的对象，hrs为所有的列表对象。


SearchCurrentSession() {
    this.getRequest("/chat/" + this.SearchHr).then(resp => {
     if (resp) {
      this.hr = resp;
      this.SearchHr = '';
      this.changeCurrentSession(this.hr);
      let it = 0;
      this.hrs.forEach((item, index) => {
       if (item.name == this.hr.name) {
        it = index;
       }
      })
      document.getElementById(it).scrollIntoView();
      // document.getElementsByClassName("active")[0].scrollIntoView();

     }
    });




 changeCurrentSession(currentSession) {
    this.$store.commit('changeCurrentSession', currentSession)
   },


页面全部代码：


<template>

 <div style="display: flex;justify-content:space-between;height: 100%;width: 100%">
  <div class="leftlist">

   <el-menu background-color="#2e3238" router
      class="el-menu-vertical-demo"
      active-text-color="#67C23A"
      text-color="#fff"
      :collapse="isCollapse">
    <el-menu-item index="/chat" style="padding-left: 10px;margin:10px 0px 20px 2px">
     <el-tooltip effect="light" placement="right-start" popper-class="el-scrollbar">
      <div slot="content">

       <div style="margin-top: 5px;font-size: 13px;lineHeight:1.5;">
        <div>用户名：{{user.name}}</div>
        <div>手机号码：{{user.phone}}</div>
        <div>电话号码：{{user.telephone}}</div>
        <div>地 址：{{user.address}}</div>
        <div>备注：{{user.remark}}</div>
       </div>
      </div>
      <img class="avatar"
        :src="/UploadFiles/2021-04-02/user.userface">
