我有一個根據使用者成員資格狀態呈現文字的元件，我想根據該屬性值更改插值文字。除了使用 v-if 或 v-show 的一堆 div/p 標籤之外，是否有更有效的方法根據 prop 顯示不同的文字？
不斷地有一堆堆疊的 div 只是大量的文字。
如有任何建議，我們將不勝感激！
乾杯！
<script lang="ts" setup>
import { PropType } from 'vue'
const props = defineProps({
kind: {
type: String as PropType<'subscribed' | 'unsubscribed'>,
default: 'subscribed',
},
planId: {
type: String as PropType<'standard' | 'silver' | 'gold' | 'platinum' | 'diamond' | 'no plan'>,
default: 'standard',
},
})
</script>
<template>
<div class="c-promotion-plan-card" data-cy="component-promotion-plan-card">
<div class="flex items-baseline mb-sm">
<div v-if="planId === 'standard'" class="text-h6 text-dark">Standard Gang</div>
<div v-if="planId === 'silver'" class="text-h6 text-dark">Silver Foxes</div>
<div v-if="planId === 'gold'" class="text-h6 text-dark">Golden Girls</div>
<div v-if="planId === 'platinum'" class="text-h6 text-dark">Platinum Boys</div>
<div v-if="planId === 'diamond'" class="text-h6 text-dark">Diamond Dudes</div>
<div v-if="planId === 'no plan'" class="text-h6 text-dark">
No Plan Posse
</div>
</div>
</div>
</template> 
是的，有更好的方法。 您可以定義一個計算屬性，例如 Vue2 語法
computed: { getLabel() { // Assuming that 'planId' is the dependency prop if(this.planId === 'standard') return 'Standard Gang'; else if(this.planId === 'silver') return 'Silver Foxes'; .... return 'No Plan Posse' // For 'no plan' condition }Vue3 語法
#setup(props) { // 1.getLabel depends on firstName,lastName. const getLabel = computed(() => { // Assuming that 'planId' is the dependency prop if(props.planId === 'standard') return 'Standard Gang'; else if(props.planId === 'silver') return 'Silver Foxes'; .... return 'No Plan Posse' // For 'no plan' condition }); return { getLabel, }; },然後在模板內呼叫插值計算，例如
也許類似於以下程式碼片段（映射您的計劃並使用計算屬性）：
const { ref, computed } = Vue const app = Vue.createApp({ props: { kind: { type: String, default: 'subscribed', }, planId: { type: String, default: 'standard', }, }, setup(props) { const plans = ref([{plan:'standard', name: 'Standard Gang'}, {plan:'silver', name: 'Silver Foxes'}, {plan:'gold', name: 'Golden Girls'}, {plan:'platinum', name: 'Platinum Boys'}, {plan:'diamond', name: 'Diamond Dudes'}, {plan: 'no plan', name: 'No Plan Posse'}]) const handlePlan = computed(() => plans.value.find(p => p.plan === props.planId)) return { plans, handlePlan } }, }) app.mount('#demo').style-class { color: red; font-size: 2em; } .other-style { color: blue; }
