利用jqGrid实现类似Excel录入功能
来源：互联网 发布：mac菜单栏怎么不隐藏 编辑：程序博客网 时间：2024/05/17 06:27
jqGrid是一个免费且功能强大的web网格控件，官方提供了十分丰富的API，几乎可以满足项目中数据展示、统计、汇总及录入需求，但也有一些不足的地方，如：不支持二堆表头、冻结列。
下列几个网站可供网友学习参考，希望对大家有所帮助。

现在我们利用jqGrid来实现录入功能，类似Excel，使用的是C#来实现，如下图所示。
第一步：
准备好相应的CSS和JS文件，
CSS文件有
Ø jquery-ui-1.7.1.custom.css(我用的是1.7.1版本)；
JS文件有
Ø jquery.js(我用的是1.4.2版本)
Ø jquery-ui-1.8.1.custom.min.js
Ø grid.locale-cn.js
Ø jquery.jqGrid.min.js
Ø jquery.jqGrid.defaults.js
其中，jquery.jqGrid.defaults.js这个文件在网络我没有下载到，是根据官方提供了资料自己编写完成的，内容如下，主要用于实现jqGrid自定义显示：
$.jgrid.defaults = { recordtext: "记录 {0} - {1} 共{2}笔", emptyrecords: "无数据显示", loadtext: "载入中...", pgtext: "第{0}页/共{1}页", altclass: "jqgrid_alternate_bgcolor"};在这里要注意一个地方，如果版本引用不匹配，样式是无法正确显示，之前我遇到过这种情况。
第二步：
新建一个aspx页面和一个JS文件，用于定义jqGrid显示及录入编辑功能的实现，在这里，我把aspx文件命名为bill.aspx，JS文件命名为”bill.js”。bill.js这个文件要记得在bill.aspx页面中引入。
其中，bill.aspx文件内容如下：
<%@ Page Language="C#" %><%@ Import Namespace="Platform.UserControl" %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title>jqGrid Demo</title> <link href="../Platform/css/themes/redmond/jquery-ui-1.7.1.custom.css"rel="stylesheet" type="text/css" /> <script type="text/javascript" src="../Platform/JS/jquery.js"></script> <script type="text/javascript" src="../Platform/JS/jquery-ui-1.8.1.custom.min.js"></script> <script type="text/javascript" src="../Platform/JS/grid.locale-cn.js"></script> <script type="text/javascript" src="../Platform/JS/jquery.jqGrid.min.js"></script> <script type="text/javascript" src="../Platform/JS/jquery.jqGrid.defaults.js"></script> <script type="text/javascript" src="js/bill.js"></script> </head><body> <table id="list1"></table> <div id="pager1"></div></body></html>
bill.js文件内容如下：
$(function () { jQuery("#list1").jqGrid({ datatype: "local", height: 80, rownumbers: true, colNames: ['品名', '包装', '计费方式', '数量', '重量', '体积', '单价', '运费', '保价金额', '保费费率', '保险费', '小计'], colModel: [ { name: 'PNAME', index: 'PNAME', width: 110, edittype: "text", editable: true, editrules: { required: true} }, //品名 {name: 'PACKAGE', index: 'PACKAGE', width: 80, edittype: "select", editable: true, editoptions: { value: "" }, editrules: { required: true} }, //包装 {name: 'BILLTYPE', index: 'BILLTYPE', width: 80, edittype: "select", editable: true, editoptions: { value: "" }, editrules: { required: true} }, //计费方式 {name: 'QUANTITY', index: 'QUANTITY', width: 50, edittype: "text", editable: true, sorttype: "int", formatter: 'integer', formatoptions: { decimalSeparator: ",", thousandsSeparator: ",", defaultValue: '0' }, editrules: { custom: true, custom_func: quantity_Check} }, //数量 {name: 'WEIGHT', index: 'WEIGHT', width: 50, align: "right", editable: true, sorttype: "float", formatter: 'currency', formatoptions: { thousandsSeparator: ",", defaultValue: '0.00' }, editrules: { custom: true, custom_func: deci_Check} }, //重量 {name: 'VOLUME', index: 'VOLUME', width: 50, align: "right", sorttype: "float", editable: true, formatter: 'currency', formatoptions: { thousandsSeparator: ",", defaultValue: '0.00' }, editrules: { custom: true, custom_func: deci_Check} }, //体积 {name: 'PRICE', index: 'PRICE', width: 50, align: "right", sorttype: "float", editable: true, formatter: 'currency', formatoptions: { thousandsSeparator: ",", defaultValue: '0.00' }, editrules: { custom: true, custom_func: deci_Check} }, //单价 {name: 'FREIGHT', index: 'FREIGHT', width: 50, sortable: false, editable: false, sorttype: "float", formatter: 'currency', formatoptions: { thousandsSeparator: ",", defaultValue: '0.00' }, editrules: { custom: true, custom_func: deci_Check} }, //运费 {name: 'INSURED', index: 'INSURED', width: 70, align: "right", editable: true, sorttype: "float", formatter: 'currency', formatoptions: { thousandsSeparator: ",", defaultValue: '0.00' }, editrules: { custom: true, custom_func: deci_Check} }, //保价金额 {name: 'PREMIUMS', index: 'PREMIUMS', width: 70, align: "right", sorttype: "float", editable: false, formatter: 'currency', formatoptions: { thousandsSeparator: ",", decimalPlaces: 3, defaultValue: '0.00' }, editrules: { custom: true, custom_func: deci_Check} }, //保险费率 {name: 'INSURANCEFEE', index: 'INSURANCEFEE', width: 70, align: "right", sorttype: "float", editable: false, formatter: 'currency', formatoptions: { thousandsSeparator: ",", defaultValue: '0.00' }, editrules: { custom: true, custom_func: deci_Check} }, //保险费 {name: 'AMOUNT', index: 'AMOUNT', width: 70, sortable: true, sorttype: "float", formatter: 'currency', formatoptions: { thousandsSeparator: ","}} //小计 ], cellEdit: true, //表示表格可编辑 cellsubmit: 'clientArray', //表示在本地进行修改 caption: "货物清单", toolbar: [true, "top"], footerrow: true, userDataOnFooter: true, altRows: true, onCellSelect: function (rowid) { goodsListID = rowid;

由于时间仓促，写得比较粗糙，有时间再改正。
