Need To Access an Array of Objects with Vue.js

Question

When the user selects a machine, I get the id of the machine. From that id I need to get the make and model of the machine.

    <ul class="list-unstyled">
          <li>
              <div v-for="dosimeter in dosimeters">
                 <label>
                    <input type="radio" name="optDosimeter" v-model="dosimeter_id" :value="dosimeter.id" v-on:click="dosimeter_select">{{dosimeter.nickname}}
                 </label>
              </div>
           </li>
     </ul>

Vue.js

    export default {
        data: function() {
            return {
              dosimeters:[],
              dosimeter_id:''
       }
     },
     mounted(){
        axios.get('/dosimeters').then((response) => {
                this.dosimeters=response.data;
            });
     },
     methods: {
         dosimeter_select(){
                not sure what to put here
            }
     }
  }

Answer 1

i think you should do something like :

  dosimeter_select(){
          let found= this.dosimeters.find(d=>{
                return d.id==this.dosimeter_id
            });

         console.log(found.make);
         console.log(found.model);
        }

Answer 2

try this

dosimeter_select()
{
 let machine =  this.dosimeters.find(dosimeter => dosimeters.id===this.dosimeter_id);
  // now you have the machine object
}

Answer 3

it should work:

 new Vue({ el: "#app", data: { dosimeters:[ { id: 1, name: 'foo' }, { id: 2, name: 'bar' } ] }, methods: { dosimeterSelected (selectedDosimeter) { console.log(`i doing something with dosimeter.id: ${selectedDosimeter.id}`) } } })

 <script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script> <div id="app"> <ul class="list-unstyled"> <li v-for="dosimeter in dosimeters"> <div> <label> <input type="radio" name="optDosimeter" :value="dosimeter.name" v-on:click="dosimeterSelected(dosimeter)">{{dosimeter.name}} </label> </div> </li> </ul> </div>

Answer 4

I made some changes now it works. I used the suggestion from Boussadjra Brahim:

dosimeter_select(){
      let found= this.dosimeters.find(d=>{
            return d.id==this.dosimeter_id
        });

     console.log(found.make);
     console.log(found.model);
    }

and rather than using radio buttons I made it a select drop down. Also, rather than triggering the method with @click, I used @change.
