    复制代码 
    <template>
  <el-container>
    <el-menu  class="el-menu-vertical-demo" style="width: 80px; height: 100vh;"

              background-color="#545c64"
              text-color="#fff"
              active-text-color="#ffd04b"
              @select="handleSelect" @open="handleOpen" @close="handleClose" :collapse="isCollapse">
      <el-menu-item :index="item.path" :key="item.path" v-for="item in sidebarRouters" v-if="item.meta" >
        <i class="el-icon-menu">
          <div style="font-size: 14px"><y>{{ item.meta.title.substring(0, 2) }}</y></div>
        </i>
      </el-menu-item>
    </el-menu>

    <el-menu style="width: 200px; height: 100vh;"
             class="el-menu-vertical-demo"

             text-color="#fff"
             router
             active-text-color="#ffd04b">
      <el-menu-item  :index="item.path" :key="item.path" v-for="(item , index) in menuChildArr">
        <i class="el-icon-menu"></i>
        <span >{{item.name}}</span>
      </el-menu-item>
    </el-menu>

    <div class="scroll-box">
      <el-main>
          <router-view></router-view>
      </el-main>
    </div>


  </el-container>

</template>

<style>
.el-menu-vertical-demo:not(.el-menu--collapse) {
  width: 200px;
  min-height: 400px;
}

.scroll-box {
  width: 100%;
  height: 100vh; /* 占据屏幕高度的 50% */
  overflow-y: auto; /* 垂直滚动 */
  box-sizing: border-box;
}

</style>

<script>
import store from "@/store";

export default {
  data() {
    return {
      sidebarRouters: store.getters.sidebarRouters,
      countIndex: 0,
      menuChildMap:{},
      menuChildArr:  [
        {
          name: '用户管理',
          path: '/system/user'
        },
        {
          name: '角色管理',
          path: '/system/role'
        }],
      isCollapse: true
    };
  },
  methods: {
    handleOpen(key, keyPath) {

    },
    handleSelect(key, keyPath){
      console.log("AAAAAAA="+ keyPath);
      console.log(key, keyPath);
      this.countIndex++;
      this.menuChildArr=[];
      let sidebarRouters = this.sidebarRouters;
      for (let i = 0; i < sidebarRouters.length; i++) {
        let item = sidebarRouters[i];
        if (item.meta && item.path==keyPath) {
          let title = item.meta.title;
          let children = item.children;
          for (let j = 0; j < children.length; j++) {
            let child = children[j];
            console.log("PPPPP:"+item.path+'/'+child.path);
