做Web开发的程序员,分页时在所难免的,微软GridView、AspPager等设置分页数据可以自动分页,但是这里浏览器会闪动,用户体验不是很友好,在此我整理了JQuery实现分页,并且使用。

JQuery绑定模板,显示数据
首先Default.aspx页面需要引用的JS文件
JQuery采用 1.4.1.1 下载地址:http://pan.baidu.com/share/link?shareid=3024434948&uk=2920032010
JQuery数据显示模板JS 下载地址:http://pan.baidu.com/share/link?shareid=3030793948&uk=2920032010
分页按钮样式 下载地址:http://pan.baidu.com/share/link?shareid=3146737028&uk=2920032010
Default.aspx页面js代码,如下,每页条数可以自定义,也可以放置配置文件中,queryString函数是根据URL参数名称,获取参数的值
Default.aspx页面Form代码如下,页面数据使用JQuery jTemplates绑定数据,非常方便,只需设置JSON格式数据,引用JS文件即可
ID 姓名 年龄 - {#foreach $T.table as record}
{$T.record.Id} - {$T.record.Name}
- {$T.record.Age}
- {#/for}
$T.record.Id 中Id对应的是实体类Id属性
#p#
上面Javascript方法中用到Member_Ajax.aspx页面代码如下,注意:这里是将数据已JSON格式输出到页面,配合JQuery数据模板使用,所有Member_Ajax.aspx页面,不应该包含Html标签,其代码格式如下
- <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Member_Ajax.aspx.cs" Inherits="Nick.Kuang.Web.Member_Ajax" %>
Member_Ajax.aspx cs页面代码
- protected void Page_Load(object sender, EventArgs e)
- {
- Response.Write(GetAll());
- }
- private string GetAll()
- {
- List
list = new List (); - for (int i = 0; i < 100; i++)
- {
- list.Add(new Student { Id = i, Name = "Name" + i, Age = i });
- }
- int pageIndex = GetPage();
- int pageSize = StrToInt(QueryString("pagesize"), 10); ;
- JavaScriptSerializer javascriptSerializer = new JavaScriptSerializer();
- string result = javascriptSerializer.Serialize(list.Skip(pageSize * (pageIndex - 1)).Take(pageSize).ToList());
- string response = "{\"result\" :\"1\"," +
- "\"returnval\" :\"操作成功\"," +
- "\"pagebar\" :\"" + PageBar.GetPageBar(3, "js", 2, list.Count, pageSize, pageIndex, "javascript:ajaxList(<#page#>);") + "\"," +
- "\"" + "totalCountStr" + "\":" + 10 + ",\"" + "table" + "\":" + result +
- "}";
- return response;
- }
- private static int GetPage()
- {
- int page = StrToInt(QueryString("pageIndex"), 0) < 1 ? 1 : StrToInt(QueryString("pageIndex"), 0);
- return page;
- }
- private static int StrToInt(string value, int defaultValue)
- {
- if (IsNumeric(value))
- return int.Parse(value);
- else
- return defaultValue;
- }
- ///
- /// 获取querystring
- ///
- /// 参数名
- ///
返回值 - private static string QueryString(string s)
- {
- if (HttpContext.Current.Request.QueryString[s] != null && HttpContext.Current.Request.QueryString[s] != "")
- {
- return SafetyQueryS(HttpContext.Current.Request.QueryString[s].ToString());
- }
- return string.Empty;
- }
- ///
- /// 将字符串中的一些标签过滤
- ///
- ///
- ///
- private static string SafetyQueryS(string theString)
- {
- string[] aryReg = { "'", ";", "\"", "\r", "\n", "<", ">" };
- for (int i = 0; i < aryReg.Length; i++)
- {
- theStringtheString = theString.Replace(aryReg[i], string.Empty);
- }
- return theString;
- }
- private static bool IsNumeric(string value)
- {
- System.Text.RegularExpressions.Regex myRegex = new System.Text.RegularExpressions.Regex("^[-]?[1-9]*[0-9]*$");
- if (value.Length == 0)
- {
- return false;
- }
- return myRegex.IsMatch(value);
- }
使用JavaScriptSerializer中的Serialize方法可以将Object类型数据转换成JSON格式的数据,告别以前拼接成字串的方法
Student实体类代码属性
- public class Student
- {
- public int Id { get; set; }
- public string Name { get; set; }
- public int Age { get; set; }
- }
#p#
分页中用到的PageBar类代码,分页调用Default.aspx中ajaxList函数,实现无刷新分页
- public class PageBar
- {
- ///
- /// 完整模式:数字+上下页+首末+总记录信息+指定页码翻转
- ///
- ///
- ///
- ///
- ///
- ///
- ///
- ///
- ///
- ///
- ///
- ///
- private static string GetDetailbar(string stype, int stepNum, int pageRoot, int pageFoot, int pageCount, int countNum, int pageSize, int currentPage, string Http1, string HttpM, string HttpN, int limitPage)
- {
- StringBuilder sb = new StringBuilder();
- sb.Append("
");");- //sb.Append("共" + countNum.ToString() + "条,当前第" + currentPage.ToString() + "/" + pageCount.ToString() + "页 ");
- sb.Append("共" + countNum.ToString() + "条记录/" + pageCount.ToString() + "页 ");
- if (countNum > pageSize)
- {
- if (currentPage != 1)//只要不是***页
- sb.Append("«");
- if (pageRoot > 1)
- {
- sb.Append("1..");
- }
- if (stepNum > 0)
- {
- for (int i = pageRoot; i <= pageFoot; i++)
- {
- if (i == currentPage)
- sb.Append("" + i.ToString() + "");
- else
- sb.Append("" + i.ToString() + "");
- if (i == pageCount)
- break;
- }
- }
- if (pageFoot < pageCount)
- {
- sb.Append(".." + pageCount + "");
- }
- if (currentPage != pageCount)//只要不是***一页
- sb.Append("»");
- if (stype == "html")
- sb.Append("转到第 ',this.value); return false;}\" /> 页");
- }
- sb.Append("
- return sb.ToString();
- }

- }
代码基本上写好了,希望对大家有用,一起学习,一起进步。
