title: v-model on input type files vue.js
body: <p>How to take data from v-model array in input type="file" multiple ?</p>
  
  <pre><code>&lt;input type="file" multiple v-model="modFiles[index]"&gt;
  &lt;input type="file" multiple v-model="modFiles[index]"&gt;
  &lt;input type="file" multiple v-model="modFiles[index]"&gt;
  </code></pre>
  
  <p>I'm using v-for loop and I can get the first data from each modFiles[].</p>
  
  <pre><code>this.modFiles[0] //take the first from multiple file
  </code></pre>
  
  <p>But it's only the first data.
  How can I take all the data inside modFiles[0],modFiles[1],modFiles[3] ?
  And how to count the data inside each modFiles ?</p>
  
  <pre><code>this.modFiles[0].length //i get error here
  </code></pre>
  
  <p>thanks so much</p>
