如何在值输入文本上显示选择选项的值？ （vue.js 2）

Question

My code is like this :

<div id="demo">
  <div>
    <select class="form-control" v-model="selected" required>
      <option v-for="option in options" v-bind:value="option.id">{{ option.name }}</option>
    </select>
    {{selected}}
  </div>
</div>

<input type="text" :name="elementName" v-model="{{selected}}">

After select on combo box, I want to display value of select option on the input text

I try like above code. But it does not work

Please, help me to solve my problem

Answer 1

You need to move the input inside the demo div because this is the mounted point ,

and with v-model just use quotes <input type="text" v-model="selected">
