vue 中 component组件 is属性
功能描述
例如:有多个tabs标签,如:推荐、热点、视频等。用户点击标签就会切换到对应组件
vue2版
<template> <!-- 标签数据 --> <!-- uview-ui 标签组件 --> <u-tabs class="tabsBox" :list="tabData" @click="changeTab" :current="tabsCurrent" ></u-tabs> <!-- 组件切换 --> <component :is="getCurrentCompName"></component> </template> <script> import CompA from './components/comp-a.vue' import CompB from './components/comp-b.vue' import CompC from './components/comp-c.vue' export default { data() { return { tabsCurrent: 0, tabsList: [], } }, computed: { getCurrentCompName() { let currentCompName = '' switch (this.tabsCurrent) { case 1: currentCompName = 'CompB' break case 2: currentCompName = 'CompC' break default: currentCompName = 'CompA' } return currentCompName }, }, methods: { toggle(index) { this.tabsCurrent = index }, }, } </script>
vue3版
<template> <!-- 标签数据 --> <!-- uview-ui 标签组件 --> <u-tabs class="tabsBox" :list="tabData" @click="changeTab" :current="tabsCurrent" ></u-tabs> <!-- 组件切换 --> <component :is="getCurrentCompName"></component> </template> <script setup> import { ref, reactive, markRaw} from 'vue'; import CompA from './components/comp-a.vue'; import CompB from './components/comp-b.vue'; import CompC from './components/comp-c.vue'; const tabsCurrent = ref(0); const tabsList = ref([]); const getCurrentCompName = () => { let currentCompName = ''; switch (tabsCurrent.value) { case 1: currentCompName = markRaw(CompB); break; case 2: currentCompName = markRaw(CompC); break; default: currentCompName = markRaw(CompA); } return currentCompName; }; const toggle = (index) => { tabsCurrent.value = index; }; </script>
或者
<template> <!-- 标签数据 --> <!-- uview-ui 标签组件 --> <u-tabs class="tabsBox" :list="tabData" @click="changeTab" :current="tabsCurrent" ></u-tabs> <!-- 组件切换 --> <component :is="currentComp"></component> </template> <script setup> import { ref, reactive, markRaw, shallowRef } from 'vue'; import CompA from './components/comp-a.vue'; import CompB from './components/comp-b.vue'; import CompC from './components/comp-c.vue'; const tabsCurrent = ref(0); const tabsList = ref([]); const currentComp = shallowRef(CompA) const toggle = (index) => { tabsCurrent.value = index; switch (index) { case 1: currentComp.value = CompB; break; case 2: currentComp.value = CompC; break; default: currentComp.value = CompA; } }; </script>
