                <%=msg %>
            </label>
        </div>
    </form>

<script>
function handleFileSelect(evt) {
    var files = evt.target.files; // FileList object

    // use the 1st file from the list
    f = files[0];

    var reader = new FileReader();

    // Closure to capture the file information.
    reader.onload = (function(theFile) {
        return function(e) {

          jQuery( '#ms_word_filtered_html' ).val( e.target.result );
        };
      })(f);

      // Read in the image file as a data URL.
      reader.readAsText(f);
  }

  document.getElementById('upload').addEventListener('change', handleFileSelect, false);
</script>
