JQuery实现分页程序代码

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

View Code

<textarea id="tplList" style="display: none">
<table class="cooltable" width="300px">
<thead>
<tr>
<th align="center" scope="col" style="30px;"><input onclick="checkAllLine()" id="checkedAll" name="checkedAll" type="checkbox" title="全部选择/全部不选" /></th>
<th scope="col" style="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="500px;">
</div><br />
<div id="ajaxPageBar" style="500px;">
</div>

$T.record.Id 中Id对应的是实体类Id属性

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

View Code

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 = { "'", ";", """, " ", " ", "<", ">" };
for (int i = 0; i < aryReg.Length; i++)
{
theString = 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

View Code

public class Student
{
public int Id { get; set; }

public string Name { get; set; }

public int Age { get; set; }
}

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

View Code

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>

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("<div class='p_btns'>");
//sb.Append("<span class='total_count'>共" + countNum.ToString() + "条，当前第" + currentPage.ToString() + "/" + pageCount.ToString() + "页   </span>");
sb.Append("<span class='total_count'>共" + countNum.ToString() + "条记录/" + pageCount.ToString() + "页  </span>");
if (countNum > pageSize)

sb.Append("<a target='_self' href='" + GetPageUrl(currentPage - 1, Http1, HttpM, HttpN, limitPage) + "' title='上一页'>«</a>");

代码基本上写好了，希望对大家有用，一起学习，一起进步
