1.tab切換 時每次想后臺返回一個唯一的name參數，就可以實現tab切換

  <div class="cate">推薦閱讀</div>
          <el-tabs v-model="activeName" @tab-click="handleClick">
            <el-tab-pane label="最近30天" name="30"></el-tab-pane>
            <el-tab-pane label="本年度" name="365"></el-tab-pane>
            <el-tab-pane label="總排行" name="all"></el-tab-pane>
          </el-tabs>
          <ul>
            <li v-for="(item, index) in recommandList" :key="index">
              <div class="title">
                <a :href="'/post/' + (item.uid || item.id)" target="_blank">
                  <span class="list-index">{{ index + 1 }}</span
                  >{{ item.title }}
                </a>
              </div>
              <div class="excerpt">
                <span class="views el-icon-date"> {{ item.createDate }}</span>
                <span class="views el-icon-view"> 閱讀({{ item.views }})</span>
              </div>
            </li>
          </ul>
          <script>
import {
  getRecomListApi4Brower,
} from "../../pages/post/index";
export default {
  props: {},
  data() {
    return {
      recommandList: [],

    };
  },
  computed: {},
  methods: {
 
    async getRecomList(type) {
      let res = await getRecomListApi4Brower({ type });
      if (res) {
        this.recommandList = res.data.slice(0,6) //只展示五條
         console.log("數據",this.recommandList);
      }
    },
    // tab.name唯一標識
    handleClick(tab, event) {
      // console.log(tab, event);
      this.getRecomList(tab.name);
    }
  },
};
</script>

2.如果后臺返回的是一個數組對象嵌套子數組數據的結構，可以雙層for循環出來直接每一項展示
