title: How to get files from <input type='file' …/> in ClojureScript
body: <p>I'm trying to get image file in input field but I could not do it. Here is the code: </p>
  
  <pre><code>:on-change (fn [_]
               (this-as this
                 (println "Files: " (.-files this))))
  </code></pre>
  
  <p>But <code>(.-files this)</code> returns <strong>nil</strong>.</p>
  
  <p>Any ideas?</p>
  
  <p>P.S: I would like to upload this image to my server.</p>
