title: IE doesn't allow to upload the file, if it is not keybord click for input type=file
body: <p>I have a requirement where i need to trigger the input[type=file] from another button and upload the files. This input[type=file] is a popup window for browsing the file which the user wants to upload. This window opens successfully but when uploading the file, it gives me <code>SCRIPT5: Access is Denied error</code> . I cannot replace the fake button with input[type=file], is there a way i can trigger click on input[type=file] even it is not from keyboard click and still upload the file. As per my research IE doesn't allow upload file unless we trigger input-type=file via keyboard click. </p>
  
  <pre><code>var uploadConfig ={
      init: function(){
          $('input#fileUpld_input').livequery("click",function() {
          });
      },
      open: function() {
          $('input#fileUpld_input').trigger('click');
      },
      upload: function(){
          $('.start').click();
      }
  </code></pre>
  
  <h2>Browser</h2>
  
  <pre><code>&lt;input type="file" id="fileUpld_input" name="fileUpld_input" class="fileUpld"&gt;
  </code></pre>
