效果图

标题实现代码

//.vue单文件

<template>
  <div :class="bemCss('tabs')">
    <el-tabs v-model="activeName" @tab-click="handleClick">
      <el-tab-pane

//使用代码

<script>
    //开始生成测试数据
    const demoData = [];
    const demoDataNum = 5;
    let active = "";
    const tabName = ["tab-one", "tab-two", "tab-three", "tab-four", "tab-five"];
    for (let i = 0; i < demoDataNum; i++) {
      demoData.push({
        labelName: Mock.mock("@ctitle(2, 5)"),
        tabName: tabName[i],
        show: Mock.mock({
          "boolean|1": true,
        }).boolean,
      });
    }
    for (let i = 0; i < demoDataNum; i++) {
      if (demoData[i].show === true) {
        active = demoData[i].tabName;
        break;
      }
    }
    Vue.component("tab-one", {
      template: "<div>This is tab one.</div>",
    });
    Vue.component("tab-two", {
      template: "<div>This is tab two.</div>",
    });
    Vue.component("tab-three", {
      template: "<div>This is tab three.</div>",
    });
    Vue.component("tab-four", {
      template: "<div>This is tab four.</div>",
    });
    Vue.component("tab-five", {
      template: "<div>This is tab five.</div>",
    });
    new Vue({
      el: "#app",
      data() {
        return {
          option: {
            currentTabComponent:active,
            activeName: active,
            cardSpan: 4,
            tabsData: demoData,
          },
        };
      },
      methods: {},
    });
  </script>

关键代码

@tab-click="handleClick"

这个是el-tabs官方给出的切换标签页使用的方法

:name="item.tabName"

绑定每个el-tab-pane的name

<keep-alive>
     <component :is="currentTabComponent"></component>
</keep-alive>

动态加载组件，这个在vue.js官方文档中可以找到

handleClick(tab) {
      this.currentTabComponent=tab.paneName;
},

通过在控制台输出tab我们可以看到，tab中的paneName属性值就和我们绑定的tabName是同一个值，所以用这个来确定当前加载的组件是什么，让tabName和组件名称相同就可以实现组件的动态切换了，只需要在使用的时候import你要用的页面组件就好了

以上代码在组件开发框架下开发，所以直接拿来使用的话需要做修改，建议看懂了之后再参考编写
