What is the best way to display only the top winner in a v-for loop?

How can I print only one winner within a v-for loop?

<div id="app">
   <div v-for="user in users">
       <div v-if="user.is_winner == 'winner'">
         <p>{{user.name}}</p>
       </div>
   </div>
</div>

app:

new Vue({
    el: '#app',
    data: {
        users: [{
            "name": "Mike",
            "is_winner": "winner"
        }, {
            "name": "Piter",
            "is_winner": "fail"
        }, {
            "name": "Jow",
            "is_winner": "fail"
        }, {
            "name": "John",
            "is_winner": "winner"
        }]
    }
})

I'm trying to display just one winner, regardless of the name.

Answer №1

The contents within the users array are not in the correct format. To only display the first winner, you can utilize the following code snippet:

<div id="app">
  <p> {{users.find(u => u.is_winner == 'winner').name}}</p>
</div>

This approach eliminates the need for a v-for loop altogether. However, it is essential to consider filtering the data before presenting them on your view (HTML), depending on your application's objective and the actual purpose of the users array.

Answer №2

If you're working on a Vue application, one way to tackle this is by utilizing a computed property:

new Vue({
  el: '#app',
  data: {
    users: [    
    {
      "name": "Mike",
      "is_winner": "winner"
    }, 
    {
      "name": "Piter",
      "is_winner": "fail"
    }, 
    {
      "name": "Jow",
      "is_winner": "fail"
    }, 
    {
      "name": "John",
      "is_winner": "winner"
        }]
  },
  computed: {
    firstWinner () {
      return this.users.find(user => user.is_winner === "winner")
    }
  }
})
<script src="https://unpkg.com/vue"></script>

<div id="app">
   <p>{{firstWinner.name}}</p>
</div>

For a Vue application scenario, using a computed property like this would suit your needs best as it updates only when the relevant data changes.

To handle the scenario where no winner exists and avoid errors in your HTML, consider updating your code with:

   <p v-if="firstWinner !== undefined">{{firstWinner.name}}</p>
