如下所示：
<tbody id="already_question_list">
<tr>
<td><?php echo $val['unique_number']; ?></td>
<td><?php echo $val['year'].'-'.$val['series']; ?></td>
<td><?php echo $val['content'] ?></td>
<td><?php echo $val['knowledges'] ?></td>
<td><?php echo $val['last_admin']; ?></td>
<td>
<input type="button" class="btn" value="－" data-score="<?php echo $val['score']; ?>" onclick='remove_selected(this);'/>\
<input type="hidden" name="question_numbers[]" value="<?php echo $val['unique_number']; ?>"/>
</td>
</tr>
</tbody>
<script>
var leng = $("#already_question_list tr").length;
var filter_numbs = new Array();
for(var i=0; i<=leng; i++)
{
numberStr = $("#already_question_list tr").eq(i).find("td:first").html();
filter_numbs.push(numberStr);
}
</script>
