Other ways of showing prop-based conditonal text in Vue?-CodePudding

I have a component that renders text based on the users membership status and I want to change the interpolated text based on that prop value. Is there a more efficient way of showing different text based on the prop besides a bunch divs/p tags withv-if or v-show?

It's just a ton of text to constantly have a bunch of stacked divs.

Any advice would be appreciated!

Cheers!

<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  data-cy="component-promotion-plan-card">
    <div >
      <div v-if="planId === 'standard'" >Standard Gang</div>
      <div v-if="planId === 'silver'" >Silver Foxes</div>
      <div v-if="planId === 'gold'" >Golden Girls</div>
      <div v-if="planId === 'platinum'" >Platinum Boys</div>
      <div v-if="planId === 'diamond'" >Diamond Dudes</div>
      <div v-if="planId === 'no plan'" >
        No Plan Posse
      </div>
    </div>
  </div>
</template>

Maybe something like following snippet (map your plans and use computed property ):

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;
}

<script src="https://unpkg.com/vue@3/dist/vue.global.prod.js"></script>
<div id="demo">
  <div  data-cy="component-promotion-plan-card">
    <div >
      <div  :>{{ handlePlan.name }}</div>
    </div>
  </div>
</div>

Yes, there is a better approach. You can define a computed property like Vue2 Syntax

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 Syntax

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,
 };
},

and then call this computed within interpolation inside you template like

<div >{{getLabel}}</div>
