UPDATE: the correct code should look like:

<script language="javascript">

  function run_copy()

  {

    $("#bx_person button[type=submit]").click();

  }

</script>

<button type="submit" value="Submit" name="do_submit_copy" class="bx-def-font-inputs bx-form-input-submit bx-btn bx-btn-primary" onclick="javascript:run_copy();">Submit</button>
