更新于2009-11-30
先看一下FlexiGrid的参数
height: 200, //flexigrid插件的高度,单位为px
width: 'auto', //宽度值,auto表示根据每列的宽度自动计算,在IE6下建议设置具体值否则会有问题
striped: true, //是否显示斑纹效果,默认是奇偶交互的形式
novstripe: false,//没用过这个属性
minwidth: 30, //列的最小宽度
minheight: 80, //列的最小高度
resizable: false, //resizable table是否可伸缩
url: false, //ajax url,ajax方式对应的url地址
method: 'POST', // data sending method,数据发送方式
dataType: 'json', // type of data loaded,数据加载的类型,xml,json
errormsg: '发生错误', //错误提升信息
usepager: false, //是否分页
nowrap: true, //是否不换行
page: 1, //current page,默认当前页
total: 1, //total pages,总页面数
useRp: true, //use the results per page select box,是否可以动态设置每页显示的结果数
rp: 25, // results per page,每页默认的结果数
rpOptions: [10, 15, 20, 25, 40, 100], //可选择设定的每页结果数
title: false, //是否包含标题
pagestat: '显示记录从{from}到{to},总数 {total} 条', //显示当前页和总页面的样式
procmsg: '正在处理数据,请稍候 ...', //正在处理的提示信息
query: '', //搜索查询的条件
qtype: '', //搜索查询的类别
qop: "Eq", //搜索的操作符
nomsg: '没有符合条件的记录存在', //无结果的提示信息
minColToggle: 1, //允许显示的最小列数
showToggleBtn: true, //是否允许显示隐藏列,该属性有bug设置成false点击头脚本报错。
hideOnSubmit: true, //是否在回调时显示遮盖
showTableToggleBtn: false, //是否显示【显示隐藏Grid】的按钮 
autoload: true, //自动加载,即第一次发起ajax请求
blockOpacity: 0.5, //透明度设置
onToggleCol: false, //当在行之间转换时,可在此方法中重写默认实现,基本无用
onChangeSort: false, //当改变排序时,可在此方法中重写默认实现,自行实现客户端排序
onSuccess: false, //成功后执行
onSubmit: false, // 调用自定义的计算函数,基本没用        


先下载FlexiGrid api

怎么导入就不说了,只要注意路径就没问题

主要步骤就上面那些,其他还有个数据库操作类&JSON操作类,
例外数据库文件我也生成好了,怎么使用我不用说了吧。
我把工程全部放上来,该工程绝对可以跑。
