视图：

<script>
    $(document).ready(function(){

控制器：

        $this->db->where($where);
        $sql_short = $this->db->get();
        $result_short = $sql_short->result_array();
        foreach($result_short as $short)
        {

                            <input type="hidden" name="jid_short" class="jid_short" id="<?php echo $short['jid']; ?>"/>

                                { 
                                    echo '<input type="checkbox" name="uid_short" id="" class="uid_short" checked disabled><span>Shortlist</span>'; 
                                }

                                }
                            ?>
                        </label>
                    </div>
                </td>
            </tr>
<?php
        }
    }
    else
    {
        echo '<p>Unable to proceed!</p>';
    }
}
?>

在这段代码中，我更新了1标题部分的uid onclick recieved上的候选列表值，并从shortlist控制器进行了响应调用，该方法工作正常但存在问题是当我单击类uid_short时，它会警告alert(uid_short);内部的多个值，我不知道我在哪里做错了吗？请帮我解决这个问题。

谢谢
