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

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
- <script type="text/javascript">
- var pagesize = 10;
- var page = thispage();
- $(document).ready(function () {
- ajaxList(page);
- });
- function queryString(pname) {
- var query = location.search.substring(1);
- var str = "";
- params = query.split("&");
- if (params.length > 0) {
- for (var n in params) {
- var pairs = params[n].split("=");
- if (pairs[0] == pname) {
- str = pairs[1];
- break;
- }
- }
- }
- return str;
- }
- function thispage() {
- var r = /^[1-9][0-9]*$/;
- if (queryString('page') == '') return 1;
- if (r.test(queryString('page')))
- return parseInt(queryString('page'));
- else
- return 1;
- }
- function ajaxList(currentpage) {
- if (currentpage != null) page = currentpage;
- $.ajax({
- type: "get",//get类型,获取用QueryString方法,post类型,用Form获取传值
- dataType: "json",
- data: "pageIndex=" + currentpage + "&pagesize=" + pagesize + "&clienttt=" + Math.random(),
- url: "Member_Ajax.aspx",
- error: function (XmlHttpRequest, textStatus, errorThrown) { alert(XmlHttpRequest.responseText); },
- success: function (d) {
- switch (d.result) {
- case '-1':
- Alert(d.returnval);
- break;
- case '0':
- Alert(d.returnval);
- break;
- case '1':
- $("#ajaxList").setTemplateElement("tplList", null, { filter_data: true });
- $("#ajaxList").processTemplate(d);
- $("#ajaxPageBar").html(d.pagebar);
- break;
- }
- }
- });
- }
- </script>
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
- <textarea id="tplList" style="display: none">
- <table class="cooltable" width="300px">
- <thead>
- <tr>
- <th align="center" scope="col" style="width:30px;"><input onclick="checkAllLine()" id="checkedAll" name="checkedAll" type="checkbox" title="全部选择/全部不选" /></th>
- <th scope="col" style="width:60px;">ID</th>
- <th width="120px">姓名</th>
- <th scope="col" width="60px">年龄</th>
- </tr>
- </thead>
- <tbody>
- {#foreach $T.table as record}
- <tr>
- <td align="center">
- <input class="checkbox" name="selectID" type="checkbox" value='{$T.record.MemberNo}' />
- </td>
- <td align="center">{$T.record.Id}</td>
- <td align="left">
- {$T.record.Name}
- </td>
- <td align="left">
- {$T.record.Age}
- </td>
- </tr>
- {#/for}
- </tbody>
- </table>
- </textarea>
- <div id="ajaxList" style="width:500px;">
- </div><br />
- <div id="ajaxPageBar" style="width:500px;">
- </div>
$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<Student> list = new List<Student>();
- 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;
- }
- /// <summary>
- /// 获取querystring
- /// </summary>
- /// <param name="s">参数名</param>
- /// <returns>返回值</returns>
- 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;
- }
- /// <summary>
- /// 将字符串中的一些标签过滤
- /// </summary>
- /// <param name="theString"></param>
- /// <returns></returns>
- 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
- {
- /// <summary>
- /// 完整模式:数字+上下页+首末+总记录信息+指定页码翻转
- /// </summary>
- /// <param name="stype"></param>
- /// <param name="stepNum"></param>

代码基本上写好了,希望对大家有用,一起学习,一起进步。
