Is it possible to have Vue.js code within a v-for loop in such a way that it executes every time the v-for loop runs?

<div class="questions" v-for="(q,index) in questions " :key="index" {{this.idx+=1}} >
        <h3 >  {{q.content}}</h3>
        <h3> A) {{q.a}}  </h3>
        <h3> B) {q.b}} </h3> 
        <h3> C) {{q.c}} </h3>
        <h3> D) {{q.d}} </h3>
        <v-btn  :id="idx"  dark class="btn-right deep-purple darken-3" v-if="veritabani"  
@click="add(q)" > Add </v-btn>
       
</div>

Working on implementing the code snippet {{this.idx+=1}}. I am anticipating its functionality here without printing the result.

Answer №1

To optimize the process, one effective approach is to create a function that cycles through question collections and updates the state index count accordingly. This function can be executed once the questions API promise is fulfilled or by monitoring changes in the questions variables and triggering the function accordingly.

Answer №2

  • Outputting Data with Interpolation is a safe way to display data on the page, avoiding execution of arbitrary code
  • Avoid utilizing this in template files
  • It's important to note that attempting to modify reactive data during template rendering can result in an infinite loop and application crashes
