ajax 无刷新分页

一.分页类

<?php

namespace Org\Util;

class AjaxPage {

    // 分页栏每页显示的页数

    public $rollPage = 5;

    // 页数跳转时要带的参数

    public $parameter  ;

    // 默认列表每页显示行数

    public $listRows = 20;

    // 起始行数

    public $firstRow ;

    // 分页总页面数

    protected $totalPages  ;

    // 总行数

    protected $totalRows  ;

    // 当前页数

    protected $nowPage    ;

    // 分页的栏的总页数

    protected $coolPages   ;

    // 分页显示定制

    protected $config  = array('header'=>'条记录','prev'=>'上一页','next'=>'下一页','first'=>'第一页','last'=>'最后一页','theme'=>' %totalRow% %header% %nowPage%/%totalPage% 页 %upPage% %downPage% %first%  %prePage%  %linkPage%  %nextPage% %end%');

    // 默认分页变量名

    protected $varPage;

    public function __construct($totalRows,$listRows='',$ajax_func,$parameter='') {

        $this->totalRows = $totalRows;

        $this->ajax_func = $ajax_func;

        $this->parameter = $parameter;

        $this->varPage = C('VAR_PAGE') ? C('VAR_PAGE') : 'p' ;

        if(!empty($listRows)) {

            $this->listRows = intval($listRows);

        }

        $this->totalPages = ceil($this->totalRows/$this->listRows);     //总页数

        $this->coolPages  = ceil($this->totalPages/$this->rollPage);

        $this->nowPage  = !empty($_GET[$this->varPage])?intval($_GET[$this->varPage]):1;

        if(!empty($this->totalPages) && $this->nowPage>$this->totalPages) {

            $this->nowPage = $this->totalPages;

        }

        $this->firstRow = $this->listRows*($this->nowPage-1);

    }

public function setConfig($name,$value) {

        if(isset($this->config[$name])) {

            $this->config[$name]    =   $value;

        }

    }

    public function show() {

        if(0 == $this->totalRows) return '';

        $p = $this->varPage;

        $nowCoolPage      = ceil($this->nowPage/$this->rollPage);

        $url  =  $_SERVER['REQUEST_URI'].(strpos($_SERVER['REQUEST_URI'],'?')?'':"?").$this->parameter;

        $parse = parse_url($url);

        if(isset($parse['query'])) {

            parse_str($parse['query'],$params);

            unset($params[$p]);

            $url   =  $parse['path'].'?'.http_build_query($params);

        }

        //上下翻页字符串

        $upRow   = $this->nowPage-1;

        $downRow = $this->nowPage+1;

        if ($upRow>0){

            $upPage="<a id='big' href='javascript:".$this->ajax_func."(".$upRow.")'>".$this->config['prev']."</a>";

        }else{

            $upPage="";

        }

if ($downRow <= $this->totalPages){

            $downPage="<a id='big' href='javascript:".$this->ajax_func."(".$downRow.")'>".$this->config['next']."</a>";

        }else{

            $downPage="";

        }

        // << < > >>

        if($nowCoolPage == 1){

            $theFirst = "";

            $prePage = "";

        }else{

            $preRow =  $this->nowPage-$this->rollPage;

            $prePage = "<a id='big' href='javascript:".$this->ajax_func."(".$preRow.")'>上".$this->rollPage."页</a>";

            $theFirst = "<a id='big' href='javascript:".$this->ajax_func."(1)' >".$this->config['first']."</a>";

        }

        if($nowCoolPage == $this->coolPages){

            $nextPage = "";

            $theEnd="";

        }else{

            $nextRow = $this->nowPage+$this->rollPage;

            $theEndRow = $this->totalPages;

            $nextPage = "<a id='big' href='javascript:".$this->ajax_func."(".$nextRow.")' >下".$this->rollPage."页</a>";

            $theEnd = "<a id='big' href='javascript:".$this->ajax_func."(".$theEndRow.")' >".$this->config['last']."</a>";

        }

        // 1 2 3 4 5

        $linkPage = "";

        for($i=1;$i<=$this->rollPage;$i++){

            $page=($nowCoolPage-1)*$this->rollPage+$i;

            if($page!=$this->nowPage){

                if($page<=$this->totalPages){

                   $linkPage .= " <a id='big' href='javascript:".$this->ajax_func."(".$page.")'> ".$page." </a>";

                }else{

                    break;

                }

            }else{

                if($this->totalPages != 1){

                    $linkPage .= " <span class='current'>".$page."</span>";

                }

            }

        }

        $pageStr  =  str_replace(

            array('%header%','%nowPage%','%totalRow%','%totalPage%','%upPage%','%downPage%','%first%','%prePage%','%linkPage%','%nextPage%','%end%'),

            array($this->config['header'],$this->nowPage,$this->totalRows,$this->totalPages,$upPage,$downPage,$theFirst,$prePage,$linkPage,$nextPage,$theEnd),$this->config['theme']);

        return $pageStr;

    }

}

?>

二.控制器代码

public function news(){

       $credit = M('news');

       $count = $credit->count(); //计算记录数

       $limitRows = 5; // 设置每页记录数

       

       $p = new \Org\Util\AjaxPage($count, $limitRows,"news"); //第三个参数是你需要调用换页的ajax函数名

       $limit_value = $p->firstRow . "," . $p->listRows;

       

       $data = $credit->order('news_id desc')->limit($limit_value)->select(); // 查询数据

       $page = $p->show(); // 产生分页信息，AJAX的连接在此处生成

       $this->assign('list',$data);

       $this->assign('page',$page);

       $this->display('Ajax_news');    

}

三.模板中代码



<html>

 

    <head>

 

        <title>Ajax无刷新分页</title>

 

        <script type="text/javascript" src="__PUBLIC__/Ajax_js/jquery-1.11.1.min.js"></script>

 

        <script type="text/javascript">

 

            function news(id){    //news函数名 一定要和action中的第三个参数一致上面有

 

                 var id = id;

 

                    $.get('{:U("Home/Index/news")}', {'p':id}, function(data){  //IndexAction中的用get方法发送信息到news方法,注意此处的链接

 

                     $("#news").replaceWith("<div  id='news'>"+data+"</div>"); //news一定要和tpl中的一致

 

                });

 

             }          

 

        </script>

 

    </head>

 

    <body>

 

       <div id='news'>   <!--这里的news和上面js中的news要一致-->

 

               <table>

 

               <foreach item='v' name='list'>

 

                     <tr><td>{$v.news_id}</td><td>{$v.news_title}</td></tr>

 

               </foreach>

 

               </table>

 

            {$page}

 

          </div>

 

    </body>

 

</html>
