这段代码是 pager分页控件的核心功能了

代码如下

复制代码

$.fn.extend({ JPager: function (cfg, pageIndex, pageSize) {
if (cfg && pageIndex > 0 && pageSize>0) {
var token = "#" + this.attr("id");
this.empty();
var pageFirst = function () {
$(token).JPager(cfg, 1, pageSize);
};
var pagePre = function () {
$(token).JPager(cfg, pageIndex - 1, pageSize);
};
var pageLast = function () {
$(token).JPager(cfg, parseInt($("#_tot").val()), pageSize);
};
var pageNext = function () {
$(token).JPager(cfg, pageIndex + 1, pageSize);
};
var pageNumber = function () {
$(token).JPager(cfg, parseInt($(this).text()), pageSize);
};
var pageGo = function () {
var index = parseInt($("#_pos").val());
var total = parseInt($("#_tot").val());
if (index) {
if (index > total) {
$(token).JPager(cfg, total, pageSize);
}
else if (index < 1) {
$(token).JPager(cfg, 1, pageSize);
}
else {
$(token).JPager(cfg, index, pageSize);
}
}
};
var checkGoNumber = function () {
if (!Number(this.value)) {
this.value = "";
}
else {
this.value = Number(this.value);
}
};
var initCustomer = function (recordCount) {
if (cfg.customer) {
if (cfg.customer.template) {
var t = cfg.customer.template;
t = t.replace(/%total%/gi, Math.ceil(recordCount / pageSize)).replace(/%current%/gi, pageIndex).replace(/%recordCount%/gi, recordCount).replace(/%pageSize%/gi, pageSize);
if (cfg.customer.position == "right") {
$("#_right").after(t);
}
else {
$("#_left").before(t);
}
}
}
};
var changeState = function (total) {
if (pageIndex == 1) {
$("#_first").attr("class", "unable");
$("#_pre").attr("class", "unable");
}
else {
$("#_first").bind("click", pageFirst).attr("class", "number");
$("#_pre").bind("click", pagePre).attr("class", "number");
}
if (pageIndex == total) {
$("#_last").attr("class", "unable");
$("#_next").attr("class", "unable");
}
else {
$("#_last").bind("click", pageLast).attr("class", "number");
$("#_next").bind("click", pageNext).attr("class", "number");
}
};
var initNumber = function (total, count, current) {
if (total > 0 && count > 0) {
if (current < 1) {
current = 1;
}
if (current > total) {
current = total;
}
var endIndex = total;
var startIndex = 1;
var temp = current + Math.floor(count / 2);
if (temp < total) {
if (temp < count) {
endIndex = count;
}
else {
startIndex = temp - count + 1;
endIndex = temp;
}
}
else {
if (total > count) {
startIndex = total - count + 1;
}
}
$("#_number").empty();
for (var i = startIndex; i <= endIndex; i++) {
var html = $("").text(i).bind("click", pageNumber);
if (i == current) {
$("#_number").append(html.attr("class", "selected"));
}
else {
$("#_number").append(html.attr("class", "number"));
}
}
}
};
var initPager = function (data) {
if ($.isArray(data.SearchResult) && data.RecordCount > 0) {
$(token).append("首页上一页下一页末页");
var total = Math.ceil(data.RecordCount / pageSize);
$("#_tot").val(total);
$("#_pos").bind("blur", checkGoNumber);
$("#_to").bind("click", pageGo);
changeState(total);
if (cfg.showNumber && cfg.count > 0) {
initNumber(total, cfg.count, pageIndex);
}
initCustomer(data.RecordCount);
}
};
if (cfg.action) {
if (cfg.action.url && cfg.action.data) {
var d = cfg.action.data.substr(0, cfg.action.data.lastIndexOf("}")) + ',"pageIndex":' + pageIndex + ',"pageSize":' + pageSize + "}";
if (cfg.action.callback && $.isFunction(cfg.action.callback)) {
$.ajax({
type: "post",
url: cfg.action.url,
dataType: "json",
contentType: "text/json",
data: d,
success: function (data) {
initPager(data.d);
cfg.action.callback(data.d);
}
});
}
else {
$.ajax({
type: "post",
url: cfg.action.url,
dataType: "json",
contentType: "text/json",
data: d,
success: function (data) {
initPager(data.d);
}
});
}
}
}
}
}
});

下面是个简单的pager的分页css样式

代码如下	复制代码
#_pos { width: 40px; } .unable { color: #BCC0BB; } .number { margin: 2px; color:#0000FF; text-decoration:underline; } .selected { margin: 2px; color: #FF0000; font-weight: bold; }

下而这调用pager分页的一个html文件

代码如下

复制代码

分页控件示例

scf文件，

代码如下

复制代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.ServiceModel.Activation;
using System.ServiceModel.Web;
namespace JPlugin
{
[ServiceContract]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class JService
{
[OperationContract]
[WebInvoke]
public PageObject GetPersons(string name,int pageIndex,int paseSize)
{
return new PageObject(){RecordCount = 23,SearchResult = new List(){new Person(){Name="zhpulq",Age = 28},new Person(){Name = "zhouxy",Age = 24}}};
}
}
public class PageObject
{
public int RecordCount { get; set; }
public List SearchResult { get; set; }
}
}
