最近在网上看见很多关于thinkphp ajax无刷新分页的实例及说明都没有办法很容易的进行 所以我现在进行讲解和分析。这里已THINKPHP3.0 开始讲解

首先需要一个ajax的分页类

找到ThinkPHPExtendLibraryORGUtil 目录下的Page.class.php

复制一个Page.class.php 更改名字为AjaxPage.class.php 让这2个文件处与同一目录


// +----------------------------------------------------------------------
// $Id: Page.class.php 2712 2012-02-06 10:12:49Z liu21st $

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){
            $upPage="".$this->config['prev']."";
        }else{
            $upPage="";
        }

if ($downRow <= $this->totalPages){
            $downPage="".$this->config['next']."";
        }else{
            $downPage="";
        }
        // << < > >>
        if($nowCoolPage == 1){
            $theFirst = "";
            $prePage = "";
        }else{
            $preRow =  $this->nowPage-$this->rollPage;
            $prePage = "上".$this->rollPage."页";
            $theFirst = "".$this->config['first']."";
        }
        if($nowCoolPage == $this->coolPages){
            $nextPage = "";
            $theEnd="";
        }else{
            $nextRow = $this->nowPage+$this->rollPage;
            $theEndRow = $this->totalPages;
            $nextPage = "下".$this->rollPage."页";
            $theEnd = "".$this->config['last']."";
        }
        // 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){
                   $linkPage .= "  ".$page." ";
                }else{
                    break;
                }
            }else{
                if($this->totalPages != 1){
                    $linkPage .= " ".$page."";
                }
            }
        }
        $pageStr  =  str_replace(
            array('%header%','%nowPage%','%totalRow%','%totalPage%','%upPage%','%downPage%','%first%','%prePage%','%linkPage%','%nextPage%','%end%'),
            array($this->config['header'],$this->nowPage,$this->totalRows,$this->totalPages,$upPage,$downPage,$theFirst,$prePage,$linkPage,$nextPage,$theEnd),$this->config['theme']);
        return $pageStr;
    }

}

 php?>

 

以上是我自己修改过的AjaxPage类

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
    然后就要写控制器(Action)

 

public function test(){
  import("ORG.Util.AjaxPage");// 导入分页类  注意导入的是自己写的AjaxPage类
  
  $credit = M('test');
  
  $count = $credit->count(); //计算记录数
        $limitRows = 15; // 设置每页记录数
       
        $p = new AjaxPage($count, $limitRows,"test"); //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 = $credit->order('id desc')->limit($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();

 }

//这里没有进行Ajax的返回,如果需要就要自己修改AjaxPage类了哈,我觉得这样方便,就没有修改。

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
    tpl页面重要部分//这里的test 和下面js中的test要一致//内容输出

   {$list.id}{$list.test}{$page}  //分页输出++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

javascrip编写  调用了jquery 框架的哈

 

function test(id){    //test函数名 一定要和action中的第三个参数一致上面有
 var id = id;
        $.get('Test/test', {'p':id}, function(data){  //用get方法发送信息到TestAction中的test方法

     $("#test").replaceWith(""+data+""); //test一定要和tpl中的一致
    });
 }
