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" 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>
