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：
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%
String path = request.getContextPath();
%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>团客人名单列表</title>
<%@ include file="../../../include/top.jsp"%>
<script type="text/javascript">
$(function() {
var vars={
dateFrom : $.currentMonthFirstDay(),
dateTo : $.currentMonthLastDay()
};
$("input[name='startTime']").val(vars.dateFrom);
$("input[name='endTime']").val(vars.dateTo );
});
</script>

//}
});
}
}
function searchBtn() {
//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
$("#contentGroupOrderTable").setGridParam({datatype:'json', page:1}).jqGrid('setGridParam', {page:1, postData: opGrid.getParam()}).trigger("reloadGrid");
}
</script>
</body>
<%@ include file="/WEB-INF/views/component/org-user/org_user_multi.jsp"%>
</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：
function searchBtn() {
//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
$("#contentGroupOrderTable").setGridParam({datatype:'json', page:1}).jqGrid('setGridParam', {page:1, postData: opGrid.getParam()}).trigger("reloadGrid");
}只需要这样写就行：
function searchBtn() {
$("#contentGroupOrderTable").jqGrid('setGridParam', {page:1, postData: opGrid.getParam()}).trigger("reloadGrid");
}2、后台controller这可以直接这样获取到排序的字段和排序方式：
String sidx = request.getParameter("sidx");//来获得排序的列名，
String sord = request.getParameter("sord");//来获得排序方式获取值后将其传入SQL语句中啦。但是SQL语句中接受参数的地方不能使用“#”，而是使用“$”符号。
<if test="sidx != null and sidx != ''">
order by ${sidx} ${sord}
</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：
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！
