title: Input type file event after select and open a file
body: <p>I have this HTML code:</p>
  
  <pre><code>&lt;input type="file" id="mysignature_upload" onChange="readURL();"/&gt;
  </code></pre>
  
  <p>Javascript code:</p>
  
  <pre><code>function readURL(){
    alert("Hello");
  }
  </code></pre>
  
  <p>The problem with this code is, the function readURL only gets called when you select a different file, but if you select the same file over and over again, readURL cannot be executed. I want to know if there's an event that fires when you select and open a file even if the file selected is the same with the previous file selected.</p>
