Can you provide some guidance on implementing a multidimensional array with the v-model in Vue?

Looking to create a unique attribute variation feature for an e-commerce website based on user-selected attribute values.

I'm facing an issue in accessing the attribute values from the v-model and determining the appropriate data type for the v-model. Any guidance or suggestions would be greatly appreciated!

Here is the snippet of code I've been working on:

Thank you in advance!

<div v-for="(attribute, index) in attributes">
    <p>{{ attribute.name }}</p>
    <div v-for="(attributevalue,indexval) in attribute.attribute_values">
        <input v-model="attributes[index][indexval]"  :value="attributevalue.id">
        <label>{{ attributevalue.name }}</label>
    </div>
</div>
<p>Generate</p>

export default {
   props:{
     attributes:{
      type:Array
     }
   }
}

If you need to associate an 'id' with an input field, here's what you should do:

<input type="text" v-model="attributevalue.id" >

You don't actually need this attributes[index][indexval] since you're already using a nested for loop that accomplishes the same thing. Therefore, you can simply use attributevalue directly in the v-model to access its properties.

A quick note about v-model:

It serves as a binding mechanism in Vue, allowing you to pass any type of value to your component as long as it supports that type. For instance, inputs with type text accept string or numeric values.

v-model utilizes various properties and events based on the type of input element:

  • Text and textarea elements utilize the value property and trigger the input event;
  • Checkboxes and radio buttons rely on the checked property and trigger the change event;
  • Select fields make use of the value prop and fire the change event.
