纯javascript写的table加载，包含分页、数据下载功能
直接先上效果图看看先。
首先简单说明一下，后面会给所涉及到的代码都贴上来的。
1.excel图标是一个用户控件，用来触发下载
2.首页、上页......每页多少条，这一块是一个整体，你可以选择放置在表格下面，或者表格上面都可以
3.表格则也是单独的一个，自己任意设置位置
4.复选框是否显示，自己设置，并可设置绑定的值，并有自带的方法可供你用于获取选中的复选框的对象跟值
5.表格的单行、双行、点击、悬浮、标题栏、表格的样式，都可以通过设置参数来修改，图为自带的效果
6.分页默认每页10行，分页的检测、复选框选择的检测，都已封装好
7.每页显示的数量、以及跳转到第几页的事件也都已经写好
8.关于导出按钮的数据导出功能，数据查询的时候，将数据绑定到用户控件中，而导出按钮则用来检测是否有复选框，如果有复选框，则用来先检测用户选中的进行拼接导出
功能大概就上面这些了吧，先给调用的方法贴上来。
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="CommonTable.aspx.cs" Inherits="ChildrenPageFolder_CommonTable" %> <%@ Register TagPrefix="uc" TagName="tn_export" Src="~/UserControl/DataExport.ascx" %> <!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>添加表格</title> <script src="../js/CommonHtmlOperation.js" type="text/javascript"></script> <script language="javascript" type="text/javascript"> function PageInfoEvent() { var sql = "select count(*) from camera_fault t"; var sqlQueryCount = ChildrenPageFolder_CommonTable.GetFaultCount(sql).value; // 从后台获取一个总数 CommonJS.HtmlTableOperation.LoadPageTool("div_PageInfo", sqlQueryCount, TableDataEvent); // 调用分页加载的方法，传入：divID，总数，回调函数 } function TableDataEvent(nowPage) { var sql = "select * from camera_fault t"; var dt = ChildrenPageFolder_CommonTable.GetFault(sql, nowPage, CommonJS.HtmlTableOperation.ShowItemCount).value; // 从后台获取数据，DataTable类型 // 设置显示的列名，每一列绑定的值 CommonJS.HtmlTableOperation.Fields = ["CF_TYPE:故障类型", "CF_CREATEUSERNAME:申报人姓名", "CF_CREATEUSERID:申报人ID", "CF_CREATETIME:申报时间"]; CommonJS.HtmlTableOperation.SetCheckbox(true, "CF_CAMERAID"); // 设置是否显示复选框，以及复选框绑定那个列，传数据库的列名进去 // 绑定行事件 // CommonJS.HtmlTableOperation.trClickFun = trC; // CommonJS.HtmlTableOperation.trDblclickFun = trC; // CommonJS.HtmlTableOperation.trMouseFun = trC; // CommonJS.HtmlTableOperation.trOutFun = trC; CommonJS.HtmlTableOperation.LoadData("div_TableData", dt); // 加载数据。传递 divID 以及 DataTable } // 获取用户选中的复选框的value值 function GetCheckedValue() { CommonJS.HtmlTableOperation.GetCheckedValue("div_TableData"); } // 行的方法，返回行对象 function trC(obj) { alert(obj.innerHTML); } </script> </head> <body onload="PageInfoEvent();TableDataEvent(1);"> <form id="form1" runat="server"> <uc:tn_export runat="server" ID="uc_export" /> <div id="div_PageInfo"> </div> <div id="div_TableData"> </div> </form> </body> </html>
简单说说代码的调用：
1.自己定义好两个div，一个用户控件。两个div呢，一个是放置上一页下一页的位置，另外一个div则用来放置table的位置，至于用户控件，放上来之后，可以隐藏，也可以显示，这个随意。
2.PageInfoEvent的三行代码，只需要理解第三行代码就够了，第二行的代码通过ajax从后台获取一个总数。而第三行代码则是调用封装的封装代码，你需要传入三个参数，一个参数是分页按钮显示的div的ID，之后就是总数，最后一个是回调函数，该回调函数是用来当分页触发之后调用的方法，封装的方法会返回一个页数回来。
3.TableDataEvent事件中，获取页数。从后台查询该页的数据
之后里面有各种参数设置，比如：显示的列名、每个列对应绑定的数据列、是否显示复选框、复选框绑定哪个列、设置每页显示的数量、行的单击双击悬浮离开事件的绑定、表格的颜色，皆可自定义设置，当然，你若不设置，也都可以，都有默认值。
4.此处需要注意的是：数据类型暂时限制了C#中的DataTable类型，因为现有的项目全是这个类型的，所以先用这个数据类型来写这个例子，如果要用其它类型，自己改代码
5.后面还有两个方法，一个是GetCheckedValue，是获取用户选中的值。TrC呢，是在加载table数据的时候，你绑定了回调方法，那么就在回调的时候，将当前行的对象返回给你自定义
下面是自己封装好的JS方法了

下面的是ajax调用的后台的两个方法，一个是获取总数，一个是获取数据
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; using System.Data; public partial class ChildrenPageFolder_CommonTable : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { AjaxPro.Utility.RegisterTypeForAjax(typeof(ChildrenPageFolder_CommonTable)); } /// <summary> /// 执行传入的sql获取报障的数据 /// </summary> /// <param name="sql"></param> /// <returns></returns> [AjaxPro.AjaxMethod] public DataTable GetFault(string sql, int pageNum, int itemCount) { int beginNum = (pageNum - 1) * itemCount; int endNum = pageNum * itemCount; string fenyeSql = "select * from(select a.*,rownum r from (" + sql + ") a where rownum <= " + endNum + ") b where r > " + beginNum; DataTable dt = DataAccessManager.GetDataTable(fenyeSql, "PGISAPP"); return dt; } /// <summary> /// 统计sql的总数 /// </summary> /// <param name="sql"></param> /// <returns></returns> [AjaxPro.AjaxMethod] public int GetFaultCount(string sql) { int count = DataAccessManager.GetItemsCount(sql, "PGISAPP"); return count; } }
接下来的两个是用户控件的前台代码跟后台代码
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="DataExport.ascx.cs" Inherits="UserControl_DataExport" %> <asp:ImageButton ID="img_downExcel" runat="server" ImageUrl="~/images/excel.png" ToolTip="导出Excel" Width="26px" Height="26px" ImageAlign="AbsMiddle" onclick="img_downExcel_Click" /> <asp:HiddenField ID="hf_fileName" runat="server" Value="" /> <asp:HiddenField ID="hf_headStr" runat="server" Value="" /> <asp:HiddenField ID="hf_bodyStr" runat="server" Value="" />

嘿嘿，大功告成，整个过程如上，有问题再联系。
