最近在網上看見很多關于thinkphp ajax無刷新分頁的實例及說明都沒有辦法很容易的進行,所以我現在進行講解和分析,這里已THINKPHP3.0 開始講解

首先需要一個ajax的分頁類

找到ThinkPHP/Extend/Library/ORG/Util 目錄下的Page.class.php

復制一個Page.class.php 更改名字為AjaxPage.class.php 讓這2個文件處與同一目錄:

class AjaxPage {

    // 分頁欄每頁顯示的頁數

    public $rollPage = 5;

    // 頁數跳轉時要帶的參數

    public $parameter  ;

    // 默認列表每頁顯示行數

    public $listRows = 20;

    // 起始行數

    public $firstRow ;

    // 分頁總頁面數

    protected $totalPages  ;

    // 總行數

    protected $totalRows  ;

    // 當前頁數

    protected $nowPage    ;

    // 分頁的欄的總頁數

    protected $coolPages   ;

    // 分頁顯示定制

    protected $config  = array('header'=>'條記錄','prev'=>'上一頁','next'=>'下一頁','first'=>'第一頁','last'=>'最后一頁','theme'=>' %totalRow% %header% %nowPage%/%totalPage% 頁 %upPage% %downPage% %first%  %prePage%  %linkPage%  %nextPage% %end%');

    // 默認分頁變量名

    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(!emptyempty($listRows)) {

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

        }

        $this->totalPages = ceil($this->totalRows/$this->listRows);     //總頁數

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

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

        if(!emptyempty($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);

        }

        //上下翻頁字符串

        $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."頁</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."頁</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;

    }

}

?>

以上是我自己修改過的AjaxPage類

然后就要寫控制器(Action):

public function test(){

  import("ORG.Util.AjaxPage");// 導入分頁類  注意導入的是自己寫的AjaxPage類



  $credit = M('test');



  $count = $credit->count(); //計算記錄數

        $limitRows = 15; // 設置每頁記錄數



        $p = new AjaxPage($count, $limitRows,"test"); //第三個參數是你需要調用換頁的ajax函數名

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



        $data = $credit->order('id desc')->limit($limit_value)->select(); // 查詢數據

        $page = $p->show(); // 產生分頁信息，AJAX的連接在此處生成

    $this->assign('list',$data);

        $this->assign('page',$page);

        $this->display();

}

這里沒有進行Ajax的返回,如果需要就要自己修改AjaxPage類了哈,我覺得這樣方便,就沒有修改.

tpl頁面重要部分:

<div id='test'>   //這里的test 和下面js中的test要一致

<volist id='list' name='list'>   //內容輸出

   ｛$list.id｝｛$list.test｝

</volist>

{$page}  //分頁輸出

</div>

javascrip編寫,調用了jquery 框架:

function test(id){    //test函數名一定要和action中的第三個參數一致上面有

var id = id;

        $.get('Test/test', {'p':id}, function(data){  //用get方法發送信息到TestAction中的test方法

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

    });

}
