最近做项目时要用到jqGrid,先学习了一下jqGrid的使用方法，现总结如下，先从基本的说起：
1、数据显示：

jqGrid可以解析的数据有很多种，如xml、json等，在这个项目中主要用的就是json数据解析，JqGrid查询时和后台交互是很简单的，但是必须注意几个地方，废话少说，我直接上代码：

JSP代码如下：

  1. <%@ page language="java" contentType="text/html; charset=UTF-8"
  2.          pageEncoding="UTF-8"%>
  3. <%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

  19.                 dateTo : $.currentMonthLastDay()

  21.             $("input[name='startTime']").val(vars.dateFrom);

  275.                 //}

  280.     function searchBtn() {
  281.         //前端分页先将datatype会变成local,所以必须先将其变为Json，点击查询按钮时才不会触发两次，就可以一次性加载数据了
  282.         $("#contentGroupOrderTable").setGridParam({datatype:'json', page:1}).jqGrid('setGridParam', {page:1, postData: opGrid.getParam()}).trigger("reloadGrid");
  283.     }
  284. </script>
  285. </body>
  286. <%@ include file="/WEB-INF/views/component/org-user/org_user_multi.jsp"%>
  287. </html>

特别说明：

（1）、不需要添加loadonce: true和sorttype:’text’这两个属性。

（2）、按钮查询不需要这样写：

  1. function searchBtn() {
  2.         //前端分页先将datatype会变成local,所以必须先将其变为Json，点击查询按钮时才不会触发两次，就可以一次性加载数据了
  3.         $("#contentGroupOrderTable").setGridParam({datatype:'json', page:1}).jqGrid('setGridParam', {page:1, postData: opGrid.getParam()}).trigger("reloadGrid");
  4.     }

只需要这样写就行：

  1. function searchBtn() {
  2.         $("#contentGroupOrderTable").jqGrid('setGridParam', {page:1, postData: opGrid.getParam()}).trigger("reloadGrid");
  3.     }

2、后台controller这可以直接这样获取到排序的字段和排序方式：

  1. String sidx = request.getParameter("sidx");//来获得排序的列名，
  2.  String sord = request.getParameter("sord");//来获得排序方式

获取值后将其传入SQL语句中啦。但是SQL语句中接受参数的地方不能使用“#”，而是使用“$”符号。

  1. <if test="sidx != null and sidx != ''">
  2.  order by ${sidx} ${sord}
  3. </if>

3、需要将loadGrid中添加属性rowNum: 15，在controller控制层方法中带上参数Integer rows，将这个参数传入PageSize，即：

  1. pageBean.setPageSize(rows);

满足以上内容就可以将数据从数据库查询出来以JSON的数据格式传入页面，就可以进行分页、排序、查询啦！
