基于Jquery实现表格动态分页实现代码

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); 
row.find("#createTime").text(n.createTime); 
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='width: 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"); 
$("#next").attr("class","default_pgNext default_pgBtn"); 
$("#last").attr("class","default_pgLast default_pgBtn"); 
if(state1 == 1) { 
document.getElementById("first").disabled = ""; 
document.getElementById("previous").disabled = ""; 
}else if(state1 == 0){ 
document.getElementById("first").disabled = "disabled"; 
document.getElementById("previous").disabled = "disabled"; 
$("#first").attr("class","default_pgFirstDisabled default_pgBtn"); 
$("#previous").attr("class","default_pgPrevDisabled default_pgBtn"); 
}if(state2 == 1){ 
document.getElementById("next").disabled = ""; 
document.getElementById("last").disabled = ""; 
}else if(state2 == 0){ 
document.getElementById("next").disabled = "disabled"; 
document.getElementById("last").disabled = "disabled"; 
$("#next").attr("class","default_pgNextDisabled default_pgBtn"); 
$("#last").attr("class","default_pgLastDisabled default_pgBtn"); 
} 
} 
</script>

html页面代码如下：

<body> 
<div> 
<div> 
<br /> 
<table id="datas" align="center" class="listtable" width="100%" bgcolor="#CCCCCC" cellSpacing="1" cellpadding="1" style="margin-top:5px;">

<tr id="template" height="22px" bgcolor="#F9FDFF" onmouseover="javascript:this.style.backgroundColor='#FFFFCC'; return true;" onMouseOut="javascript:this.style.backgroundColor='#F9FDFF'; return true;">

后台action中代码如下：

//分页获取用户信息 
public void listUser2(ActionMapping mapping, ActionForm form, 
HttpServletRequest request, HttpServletResponse response){ 
RequestTool tool = new RequestTool(request); 
Integer pageSize = tool.getIntParameter("pageSize"); 
Integer pageIndex = tool.getIntParameter("pageIndex"); 
ResultPage res = serviceSmUserImpl.findAllSmUsers(pageIndex, pageSize); 
List<SmUser> smUserList = (List<SmUser>)res.getResult(); 
JSONArray array = new JSONArray(); 
JSONObject object ; 
for(SmUser user:smUserList){ 
object = new JSONObject(); 
object.put("userId", user.getUserId()); 
object.put("userName",user.getUserName()); 
object.put("depId", user.getOrganCode()); 
object.put("createTime", user.getCreateTime()); 
object.put("creator", user.getCreator()); 
object.put("menusId", user.getMenusId()); 
object.put("isValid", (user.getValid().equals("1")?"有效":"无效")); 
array.add(object); 
} 
AjaxTool.returnAjaxResponse(response, array.toJSONString()); 
} 
//获取总的记录数和总页数 
public void getPageCount(ActionMapping mapping, ActionForm form, 
HttpServletRequest request, HttpServletResponse response){ 
RequestTool tool = new RequestTool(request); 
int pageSize = tool.getIntParameter("pageSize"); 
List<POJO> pojos = serviceSmUserImpl.findAll(); 
int pageCount = pojos.size()% pageSize > 0 ? (pojos.size()/ pageSize+1):(pojos.size()/ pageSize); 
JSONArray array = new JSONArray(); 
JSONObject object = new JSONObject(); 
object.put("pageCount", pageCount); 
object.put("totalCount", pojos.size()); 
array.add(object); 
AjaxTool.returnAjaxResponse(response,array.toJSONString()); 
}
