component

在模板中使用元素，通过 is 特性来动态切换组件：

<template>
  <div>
    <el-tabs type="card" v-model="activeName" @tab-click="handleClick">
      <el-tab-pane label="待审核" name="1" />
      <el-tab-pane label="已通过" name="2" />
      <el-tab-pane label="未通过" name="3" />
      <el-tab-pane label="黑名单" name="4" />
    </el-tabs>
    <component
      ref="componentRef"
      :is="componentName"
      :activeName="activeName"
    ></component>
  </div>
</template>
<script setup>
import { ref, toRefs, computed, markRaw, nextTick } from "vue";
// 待提交
import PendingReview from "./pendingReview.vue";
// 已通过
import Passed from "./passed.vue";
// 未通过
import NotPass from "./notPass.vue";
// 黑名单
import Blacklist from "./blacklist.vue";
 
const componentRef = ref();
 
 
const activeName = ref("1");
const componentName = ref(markRaw(PendingReview));
 
const handleClick = (tab) => {
  if (tab.paneName === "1") {
    componentName.value = markRaw(PendingReview);
  } else if (tab.paneName === "2") {
    componentName.value = markRaw(Passed);
  } else if (tab.paneName === "3") {
    componentName.value = markRaw(NotPass);
  } else {
    componentName.value = markRaw(Blacklist);
  }
};
</script>
<style></style>

使用 v-if 或 v-show

<template>
  <div>
    <el-tabs type="card" v-model="activeName">
      <el-tab-pane label="待审核" name="1" />
      <el-tab-pane label="已通过" name="2" />
      <el-tab-pane label="未通过" name="3" />
      <el-tab-pane label="黑名单" name="4" />
    </el-tabs>
    <PendingReview v-if="activeName == '1'"/>
    <Passed v-if="activeName == '2'"/>
    <NotPass v-if="activeName == '3'"/>
    <Blacklist v-if="activeName == '4'"/>
  </div>
</template>
<script setup>
import { ref, toRefs, computed, markRaw, nextTick } from "vue";
// 待提交
import PendingReview from "./pendingReview.vue";
// 已通过
import Passed from "./passed.vue";
// 未通过
import NotPass from "./notPass.vue";
// 黑名单
import Blacklist from "./blacklist.vue";
 
const componentRef = ref();
 
const props = defineProps({
  callData: {},
});
const activeName = ref("1");
 
</script>
<style></style>
