【JqGrid】JqGrid使用后台分页+查询条件+排序

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！
