Creating dynamic templates with text interpolation in Vue 3 using the Composition API

I have a Component that requires a string property, as shown below:

<script lang="ts" setup>

    const props = defineProps<{
        transcription?: string;
    }>();
    
     watch(() => props.transcription,
         (newTranscription) => {
             if (newTranscription) {
                 console.log(newTranscription);
                 // dynamically add a paragraph with text interpolation
                 // `<p> {{ newTranscription }} </p>`
             }
          }
     );

</script>
<template>
    <h1>Transcriptions</h1>
    ...here I want to dynamically append a paragraph each time the transcription property has text
</template>

When the property contains text, I wish to include a "

<p> {{transcription}} </p>
" in the template to display the text and update based on the property content. The appending should be done dynamically. Any suggestions are highly appreciated

Answer №1

Consider implementing a computed property in your code:

<script lang="ts" setup>

    const props = defineProps<{
        transcript?: string;
    }>();
    
   const updatedTranscript = computed(() => {
             if (props.transcript) {
                 return props.transcript + "add some dynamic elements";
             }
     );

</script>

Answer №2

Construct a collection of transcriptions, such as:

<script lang="ts" setup>
    const transcriptions = [];

    const attributes = defineProps<{
        transcription?: string;
    }>();
    
     watch(() => attributes.transcription,
         (newTranscription) => {
             if (newTranscription) {
                 console.log(newTranscription);
                 //add a paragraph dynamically with text replacement
                 transcriptions.push(newTranscription);
             }
          }
     );

</script>

Utilize v-for in your template:

<p v-for="transcr in transcriptions" :key="transcr">{{transcr}}</p>

Keep in mind that the key needs to be unique, which may not be the scenario in the given sample.
