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><componentref="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>
