项目中经常会对表格进行分页，以下运用jquery对用户管理中的用户表格进行分页。
当页面点击分页图标时，程序会自动去后台获取对应页数的记录。

关键代码如下：
需要引入的css和js文件有：
<link rel="stylesheet" type="text/css" href="<%=basePath %>css/theme/default/css/jpage.css"></link>
<link ID="skin" rel="stylesheet" type="text/css" href="<%=basePath %>css/config.css" />
<script language="javascript" type="text/javascript" src="<%=basePath %>js/jquery.js"></script>
其中jsp页面代码如下：
<script language="jscript" type="text/javascript">
var pageIndex = 1; //当前页数
$(function(){
GetPageCount();//获取分页数量以及总的记录条数
$("#load").hide();//隐藏loading提示
$("#template").hide();//隐藏模板
ChangeState(0,1);//设置翻页按钮的初始状态
bind();//绑定第一页的数据
//第一页按钮click事件
$("#first").click(function(){
pageIndex = 1;
ChangeState(0,1);
bind();
});
//上一页按钮click事件
$("#previous").click(function(){
pageIndex -= 1;
ChangeState(-1,1);
if(pageIndex <= 1){
pageIndex = 1;
ChangeState(0,-1);
}
bind();
});
//下一页按钮click事件
$("#next").click(function(){
pageIndex += 1;
ChangeState(1,-1);
if(pageIndex>=pageCount)
{
pageIndex = pageCount;
ChangeState(-1,0);
}
bind(pageIndex);
});
//最后一页按钮click事件
$("#last").click(function(){
pageIndex = pageCount;
ChangeState(1,0);
bind(pageIndex);
});
//每页显示记录条数select事件
$("#pageSize").change(function(){
bind();
})
});
//AJAX方法取得数据并显示到页面上
function bind(){
$("#load").show();
var pageSize = $("#pageSize").val();
$.ajax({
type: "get",//使用get方法访问后台
dataType: "json",//返回json格式的数据
url: "<%=basePath%>actionSmUser.do?method=listUser2",//要访问的后台地址
data: "pageIndex=" + pageIndex+"&pageSize="+pageSize,//要发送的数据
complete : function(msg){//msg为返回的数据，在这里做数据绑定
$("[id=ready]").remove();
var data = eval("("+msg.responseText+")");
$.each(data, function(i, n){
var row = $("#template").clone();
row.find("#userId").text(n.userId);
row.find("#userName").text(n.userName);
row.find("#depId").text(n.depId);

if(n.createTime !== undefined) row.find("#createTime").text(n.createTime);
row.find("#creator").text(n.creator);
row.find("#menusId").text(n.menusId);
row.find("#isValid").text(n.isValid);
row.attr("id","ready");//改变绑定好数据的行的id
row.appendTo("#datas");//添加到模板的容器中
});
$("[id=ready]").show();
SetPageInfo();
}
});
}
function ChangeDate(date){
return date.replace("-","/").replace("-","/");
}
//设置第几页/共几页的信息
function SetPageInfo(){
var pageCount = $("#pageCount").val();
var totalCount = $("#totalCount").val();
var pageSize = $("#pageSize").val();
$("#pageinfo").html(" 第<input class='default_pgCurrentPage' id='pageIndex' type='text' value='"+pageIndex+
"' style=' 30px' /> 页" + "/" +"共 "+pageCount+"页"+
" 检索到 "+totalCount+"条记录，显示第 "+(pageIndex*pageSize-pageSize)+" 条 - 第 "+(pageIndex*pageSize)+" 条记录");
}
//AJAX方法取得分页总数
function GetPageCount(){
var pageSize = $("#pageSize").val();
$.ajax({
type: "get",
dataType: "text",
url: "<%=basePath%>actionSmUser.do?method=getPageCount",
data: "pageSize="+pageSize ,
async: false,
success: function(msg){
var data = eval("("+msg+")");
$("#pageCount").val(data[0].pageCount);
$("#totalCount").val(data[0].totalCount);
}
});
}
//改变翻页按钮状态
function ChangeState(state1,state2){
$("#first").attr("class","default_pgFirst default_pgBtn");
$("#previous").attr("class","default_pgPrev default_pgBtn");

//分页获取用户信息
public void listUser2(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response){

array.add(object);
}
AjaxTool.returnAjaxResponse(response, array.toJSONString());
}
//获取总的记录数和总页数
