SSH实现批量删除

实现效果：

以下是部分关键代码：
Js实现多项选择

<script type="text/javascript">
          /*全选JS*/
          function CheckAll(thisform){
                  for (var i=0;ivar e = thisform.elements[i];
                          if (e.Name != "chkAll"&&e.disabled!=true)
                             e.checked = thisform.chkAll.checked;
                      }
          }
          /*判断是否选空*/
          function judge(){
            var arrayid = new Array();
            $('input[name="ids"]:checked').each(function(){arrayid.push($(this).val());});
            if(arrayid.length==0){
            alert("无实例选中");
             event.preventDefault(); // 兼容标准浏览器
            window.event.returnValue = false; // 兼容IE6~8
            }
          }
      script>

Jsp列表迭代输出

        <table cellpadding="6" cellspacing="1" bgcolor="#dddddd"
            align="center" width="600">

Dao中逐条删除用户记录

    /*
     * 根据Id值查找
     */
    public User findById(Integer id) {
        Session session = getSessionFactory().getCurrentSession();
        User user = (User) session.get(User.class, id);
        return user;
    }

    /*
     * 循环删除多条记录
     */
    public void delAll(int[] ids) {
        Session session = getSessionFactory().getCurrentSession();
        for (int i = 0; i < ids.length; i++) {
            User user = this.findById(ids[i]);
            session.delete(user);
        }
    }
