What is the best way to implement the v-for loop in a Vue.js application?

I am currently working with a loop that contains four inputs. I am looking to assign separate id values from the loop to each of these inputs. How can I achieve this? click here for image click here for image

While running a loop, I have only one input that receives values from the loop. What is the best way to ensure value retention for each individual using a v-model?

If you are working with Vuejs, it is important to structure your data properly in the return statement:

<script>
export default {
  data() {
    return {
      items: [{ message: 'Foo' }, { message: 'Bar' }]
    }
  }
}
</script>

You can then use a v-for loop to iterate over the items:

<template>
  <div v-for="(item, index) in items">
        <input :id="index" v-model="item.message" />
  </div>
</template>

For a more specific case, such as when using props like altinFiyati, you would set it up like this:

<script>
  export default {
    props: {
      altinFiyati: Object
    },
    data() {
      return {
        altinCount: this.altinFiyati,
      }
    }
  }
</script>

Then in the v-for loop, you can connect your data to the v-model input:

<template>
  <div v-for="(item, index) in altinCount">
        <input :id="index" v-model="item.message" />
  </div>
</template>

Where did things take a turn? Have you checked if your component is set up correctly to utilize v-model? Also, given that you are currently looping through the item, there is no need to include listOfItems[index] in the parameters. Simply use the v-model="item" prefix to reference the item.
