Vue.js: How to get attributes of an option in Select dropdown box?

Question

If we bind a Select box values like the following Example:

<select v-model="car">
 <option number="one">BMW</option>
 <option number="two">Audi</option>
 <option number="three">Mercedes</option>
</select>

How can I get the value of the number attribute instead of the Name of the car in Vue.js?

Answer 1

You should use value instead of number :

<select v-model="car">
 <option value="one">BMW</option>
 <option value="two">Audi</option>
 <option value="three">Mercedes</option>
</select>

selected value will be assigned to car property.

Example :

Vue.config.devtools = false;
Vue.config.productionTip = false;

new Vue({
  el: '#app',
  data() {
    return {
      car: ''
    }
  }
})

<div id="app" class="container">
  <select v-model="car">
    <option value="one">BMW</option>
    <option value="two">Audi</option>
    <option value="three">Mercedes</option>
  </select>
  
  {{car}}
</div>
