jquery easyui datagraid 对象显示的方法与datagraid、分页、复选框多选的数据显示

========================jsp==============================
<table id="dg" fit="true" width="100%">
<thead>
<tr>   
<th field="aguid" hidden="true">主键</th> 
<th field="ck" checkbox="true"></th>   
<th field="aname"  sortable="true">用户名</th> <!--sortable="true",这个属性是用户点击标题可以排序-->
<th field="guid_job"  sortable="true" formatter="formatterJob.Formatter_job">职位</th><!--这里直接写对象名，formatterJob.Formatter_job获取职务的名称-->
<th field="guid_bm" sortable="true" formatter="formatterBm.Formatter_bm">部门</th><!--这里直接写对象名，formatterBm.Formatter_bm获取部门的名称-->
<th field="mobilephone" sortable="true">手机</th>
<th field="email"  sortable="true">邮箱</th>
<th field="isworking"  sortable="true" formatter="formatterStatus.Formatter_status">状态</th><!--formatterStatus.Formatter_status格式化数据-->
<th field="isoperator" formatter="formatterisIsoperator.Formatter_isoperator">是否允许登录</th><!--formatterisIsoperator.Formatter_isoperator格式化数据-->
<th field="操作"   formatter="datagridformatter.operformatter">操作</th><!--datagridformatter.operformatter在表格的最后一格添加功能按钮-->
</tr>
</thead>

<script>
// 初始化表格数据
function loadinit() {
 $('#dg').datagrid({
  url : '/jubcrm/index/qryUser.hml',//返回后台路径
  idField : 'aguid',
  pagination : true,
  rownumbers : true,
  singleSelect : false
 });
}
</script>

===============js===============
//格式化datagrid获取对象的属性名称bm
var formatterBm = {
Formatter_bm : function(val, rec, index) {
if (val == undefined) {
return "";
}
return rec.guid_bm.aname;//返回部门名称(部门是一个对象即用户的外键)
}
};

//格式化datagrid获取对象的属性名称job
var formatterJob = {
Formatter_job : function(val, rec, index) {
if (val == undefined) {
return "";
}
return rec.guid_job.aname;//返回职务名称(职务是一个对象即用户的外键)
}
};
//格式化datagrid获取对象的属性名称isworking，该值是true或者false在jsp中需要转换成中文的格式
var formatterStatus = {
Formatter_status : function(val, rec, index) {
if (val == undefined) {
return "";
}
if(val==false){
return "在职";
}else if(val==true){
return "离职";
}
}
};

//格式化datagrid获取对象的属性名称是否操作员，该值是true或者false在jsp中需要转换成中文的格式
var formatterisIsoperator = {
Formatter_isoperator : function(val, rec, index) {
if (val == undefined) {
return "";
}
if(val==true){
return "允许登录";
}else{
return "禁止登录";
}
}
};

var datagridformatter = {
 operformatter : function (val, row, index) {
   var e = '<a href="#" onclick="editrow(' + index + ')">编辑</a> ';
   var d = '<a href="#" onclick="deleterow(' + index + ')">删除</a>';
   return e + d;
 }
};

================================java后台代码======================================

===========================业务层servicesImpl==================
 // 用户管理查询用户信息
 @SuppressWarnings("unchecked")
 public String qrypage(Pubuser pub, String page, String rows, String order,String sort) {
  StringBuffer jql = new StringBuffer();
  jql.append(" 1=1 ");
  if (szf == 65536) {
   jql.append(" and status = " + szf);
  } else if (szf == 0) {
   jql.append(" and (status=0 or status is null) ");
  }
  Boolean sxz = pub.getIsxz();
  if (sxz != null) {
   jql.append(" and isxz = " + sxz);
  }

long total = pubbasedao.getCount(Pubuser.class, jql.toString(), null);//查询总记录数

int pagenum = 1;
  if (!page) {
   pagenum =page;
  }
  int rowsnum = JToolType.defrowsnum;
  if (!rows) {
   rowsnum = rows;
  }
  if (order) {
   order = "DESC";
  }
  if (sort) {
   sort = "date_in";
  }
  
  LinkedHashMap<String, String> ordermap = new LinkedHashMap<String, String>();
  if (!order) {
   ordermap.put(sort, order);
  }
  List<Pubuser> lstrows = pubbasedao.qryPage(Pubuser.class, pagenum,
    rowsnum, jql.toString(), null, ordermap);//查询数据

return formatDataGridPage(total, lstrows);

}

/**
  * 格式化Controller返回DataGrid分页数据<br>
  * lstrows必须为list
  * fastjson-1.1.33.jar
  */
 public static String formatDataGridPage(long total, Object lstrows) {
  Map<String, Object> result = new HashMap<String, Object>();
  result.put("total", total);
  result.put("rows", lstrows);
  return parse2JSON(result);
 }

=============dao,我这里用的是JPA，如果是ssh用户基本一样=======================
 @Override
 public List<T> qryPage(Class<T> clazz, int firstindex, int maxresult,
   String whQl, Object[] params, LinkedHashMap<String, String> orderby) {
  Query q = em.createQuery("SELECT u FROM " + clazz.getSimpleName()
    + " u " + (whQl ? "" : " where " + whQl)
    +orderby);
  setQueryParams(q, params);
  if (firstindex >= 0) {
   // q.setFirstResult(firstindex);
   q.setFirstResult((firstindex - 1) * maxresult);
  }
  if (maxresult > 0) {
   q.setMaxResults(maxresult);
  }

return q.getResultList();
 }

public void setQueryParams(Query query, Object[] params) {
  try {
   if (params != null && params.length > 0) {
    for (int i = 0; i < params.length; i++) {
     query.setParameter(i + 1, params[i]);
    }
   }
  } catch (Exception e) {
   e.printStackTrace();
  }
 }
==============================控制层action，我用的是springMVC=======================================
@Controller
@RequestMapping("index")
public class PubuserAction {
 @Autowired
 public PubuserServices pub;
 // 刷新信息
 @RequestMapping("qryUser")
 public void qryUser(Pubuser pubuser, HttpServletRequest request,
   HttpServletResponse response) throws IOException {
  Pubuser us = (Pubuser) request.getSession().getAttribute(
    JToolType.AttributeUserName);
  pubuser.setGuid_gs(us.getGuid_gs());
  String rslt = pub.qrypage(pubuser, request.getParameter("page"),
    request.getParameter("rows"), request.getParameter("order"),
    request.getParameter("sort"));
  response.getWriter().write(rslt);
  response.getWriter().close();

}
