web project 批量删除

一、jsp页面

1.添加复选框

<input type="checkbox" name="delCheck"value="<bean:write name='bill' property='agBillSeq' />">

在每一条循环记录前放置一个复选框，value设为此条记录的主键

2.添加按钮

（1） <a href="#" onclick="selectAll()">全选</a>&nbsp;<a href="#" onclick="disselect()">取消</a>

（2）<input type="button" value="删除" class="btn4" onclick="del()">

3.javascript

//全选的js

function selectAll()
    {
        var allInput = document.getElementsByName("delCheck");
        var loopTime = allInput.length;
        for(i = 0;i < loopTime;i++)
        {
            if(allInput[i].type == "checkbox")
            {
                allInput[i].checked="checked";
            }
        }
    }

//取消的js

    function disselect(){
        var allInput = document.getElementsByName("delCheck");
        var loopTime = allInput.length;
        for(i = 0;i < loopTime;i++)
        {
            if(allInput[i].type == "checkbox")
            {
                allInput[i].checked="";
            }
        }
    }

//批量删除的js

function del() {
    var s=",";
    var allInput = document.getElementsByName("delCheck");
        var loopTime = allInput.length;
                for(i = 0;i < loopTime;i++)
        {
            if(allInput[i].checked == true)
            {    

                 s = s+allInput[i].value+",";
            }
        }
           if(window.confirm("你确定要删除这条记录吗？")){
        $("billForm").action = "deleteBills.do?delIds=" + s ;
        $("billForm").submit();
    }
    }

二、Action中的代码

 public ActionForward deleteBills(ActionMapping mapping,
        ActionForm form,HttpServletRequest request,HttpServletResponse response)throws Exception{
       String delIds = request.getParameter("delIds");
       billService.deleteBills(delIds);
       return mapping.findForward("deleteBills");
      }

三、Service中的代码

public void deleteBills(String delIds){
 String delId[];
 delId = delIds.split(",");
 for(int i=0;i<delId.length;i++){
  if(delId[i]!=null&&!"".equals(delId[i])){
   billDAO.deleteBill(Long.parseLong(delId[i]));
  }
 }
}

四、DAO中的代码

public void deleteBill(Long AgBillSeq){
 this.removeObject(Bill.class,AgBillSeq);
}

public void removeObject(Class clazz, Serializable id) {
        getHibernateTemplate().delete(getObject(clazz, id));
    }

注：使用SSH框架实现的，其中需要一些配置，大体思路是这样
