jquery easy ui 查询问题5

后台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");
		String stu_name = request.getParameter("stu_name");
		System.out.println(stu_id);
		System.out.println(stu_name);
		//当前页  
		int intPage = Integer.parseInt((page == null || page == "0") ? "1":page);
		//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();

js：

    	<script type="text/javascript">
	$(function(){
		  $('#dg').datagrid('getPager').pagination({
			    displayMsg:'当前显示从{from}到{to},共{total}记录',
			    onBeforeRefresh:function(pageNumber, pageSize){
			     $(this).pagination('loading');
			     $(this).pagination('loaded');
			    }
			   });
	});

前台怎么传值过去，就是说 function doSearch(){
$('#dg').datagrid('load',{
stu_id: $('#stu_id').val(),
stu_name: $('#stu_name').val(),
});
}

这块怎么写url，怎么把值传到后台
