"Troubleshooting: The v-model in my Vue project is not functioning properly when used

I am encountering an issue where the v-model directive is not functioning properly inside a v-for loop.

Within my template

<li v-for="(data, key) in product.variants" :key="data.id">
   <input type="radio" :id="'variant' + key" name="Variant" v-model="cart.variantId"/>
   <label :for="'variant' + key">{{data.variant}}</label>
</li>

within my script

data(){
   return{
     cart: {
         quantity: '1',
         colorId: '',
         variantId: '',
      },
   },

   computed: {
      // Retrieve Quick View Product
      product(){
         return this.$store.state.quickViewProduct;
      },
   },

},

Now, the solution to this issue

Answer №1

When saving a value from a group of radio buttons to a property, it's important to distinguish the buttons based on their values rather than their IDs. Here's a sample code snippet to demonstrate this:

<div v-for="(item, index) in product.selections" :key="item.id">
   <input type="radio" :id="'selection' + index" name="Selection" v-model="cart.selectionId" :value="item.id"/>
   <label :for="'selection' + index">{{item.name}}</label>
</div>
