js部分:

export default {
  data() {
    return {
      num: 0, //默认显示第一个
      list: ["遥感", "年检", "路检", "IM站治理", "预警处罚清单"],
    };
  },
  methods: {
    getNum(index) {
      console.log(index);
      this.num = index;
    }
  }
};

还有一种情况是点击选项卡直接切换路由,通过路由导航直接改变页面。

注意路由变化
<template>
  <div class="pageIndex">
    <!-- tab切换栏 -->
    <div class="tabs">
      <span :class="['tab', currentTab == 1 ? 'active' : '']" @click="turnPage(1)">遥感监测点位</span>
      <span :class="['tab', 'tab1', currentTab == 2 ? 'active' : '']" @click="turnPage(2)">机动车排放检验机构</span>
      <span :class="['tab', 'tab1', currentTab == 3 ? 'active' : '']" @click="turnPage(3)">柴油货车OBD远程监控</span>
      <span :class="['tab', 'tab1', currentTab == 4 ? 'active' : '']" @click="turnPage(4)">抽检抽查分析</span>
    </div>

    <router-view />
  </div>
</template>

<script>
export default {
  data () {
    return {
      currentTab: 1,
      showProper: true
    }
  },
  methods: {
    turnPage(v) {
      if(v === 4) return
      this.currentTab = v
      this.$router.push('/index/page' + v)
    }
  }
}
</script>

<style lang="less">
.pageIndex {
  height: 100%;
  width: 100%;
  position: relative;
  .tabs{
    font-size: 14px;
    position: absolute;
