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：

// +----------------------------------------------------------------------
// $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;
}
}
?>

控制器里写入以下内容：

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();
}
}
?>

模板文件如下：

 
 
<{$list.id}>  <{$list.username}>


<{$page}>
