在Thinkphp中使用ajax实现无刷新分页的方法

在Thinkphp目录的Lib\ORG\Util\目录里新建AjaxPage.class.php,写入一下内容：

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){ $upPage="<a href='javascript:".$this->ajax_func."(".$upRow.")'>".$this->config['prev']."</a>"; }else{ $upPage=""; } if ($downRow <= $this->totalPages){ $downPage="<a href='javascript:".$this->ajax_func."(".$downRow.")'>".$this->config['next']."</a>"; }else{ $downPage=""; } // << < > >> if($nowCoolPage == 1){ $theFirst = ""; $prePage = ""; }else{ $preRow = $this->nowPage-$this->rollPage; $prePage = "<a href='javascript:".$this->ajax_func."(".$preRow.")'>上".$this->rollPage."页</a>"; $theFirst = "<a href='javascript:".$this->ajax_func."(1)' >".$this->config['first']."</a>"; } if($nowCoolPage == $this->coolPages){ $nextPage = ""; $theEnd=""; }else{ $nextRow = $this->nowPage+$this->rollPage; $theEndRow = $this->totalPages; $nextPage = "<a href='javascript:".$this->ajax_func."(".$nextRow.")' >下".$this->rollPage."页</a>"; $theEnd = "<a href='javascript:".$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){ $linkPage .= "&nbsp;<a href='javascript:".$this->ajax_func."(".$page.")'>&nbsp;".$page."&nbsp;</a>"; }else{ break; } }else{ if($this->totalPages != 1){ $linkPage .= "&nbsp;<span>".$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; } } ?>

控制器里写入以下内容：

<?php class UserAction extends Action{ public function user(){ import("ORG.Util.AjaxPage");// 导入分页类 注意导入的是自己写的AjaxPage类 $credit = M('user'); $count = $credit->count(); //计算记录数 $limitRows = 5; // 设置每页记录数 $p = new AjaxPage($count, $limitRows,"user"); //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(); } } ?>
