title: How to change value of input type file in Jquery
body: <p>I have got this HTML code</p>
  
  <pre><code>&lt;img src="../img/1.jpg" class="img"&gt;
  &lt;img src="../img/2.jpg" class="img"&gt;
  &lt;img src="../img/3.jpg" class="img"&gt;
  &lt;img src="../img/4.jpg" class="img"&gt;
  &lt;input type="file" name="file" id="file" onchange="bgchange(this)" &gt;
  </code></pre>
  
  <p>And this jquery</p>
  
  <pre><code>$(".img").click(function(){
                          var srcat=$(this).attr('src');
                          $("#file").attr('value',srcat);
                          alert($("#file").val());
                  });
  </code></pre>
