后台java：
[code="java"]
//接受参数page和rows
String page =request.getParameter("page");//每页显示的记录数
String rows = request.getParameter("rows");//当前第几页
String stu_id = request.getParameter("stu_id");

//每页显示条数
int number = Integer.parseInt((rows == null || rows == "0") ? "10":rows);
//每页的开始记录 第一页为1 第二页为number +1
int start = (intPage-1)*number;
PrintWriter out = response.getWriter();
StudentDAO sd = new StudentDAOImpl();
//得到总共有多少条数据
int totalCount = sd.getCount(stu_id,stu_name);
ArrayList<Student> students= sd.getStudents(start,number,stu_id,stu_name);
Map<String, Object> jsonMap = new HashMap<String, Object>();//定义map
jsonMap.put("total",totalCount);//total键 存放总记录数，必须的
jsonMap.put("rows", students);//rows键 存放每页记录 list
JSONObject result = JSONObject.fromObject(jsonMap);//格式化result 一定要是JSONObject
System.out.println(result);
out.print(result.toString());
out.flush();
out.close();

你完全可以使用同一个url查询的，只是第一次传过去的参数为0，查询时传过去的参数不为0而已。然后在service层拼接sql调用dao层就可以了，不知道我说的你能否明白
定义 datagrid 时设置了URL，在调用 load 方法不需要传URL，你最后写的doSearch方法中的调用就是正确的参数传递方法。
$('#list').datagrid('options').url = '../../Ashx/News/News_Comment.ashx?func=GetList';
$('#list').datagrid("reload");
