PHP分页器制作,自动生成分面页码,JS调用函数,分页的原理大致如下,分页程序有两个非常重要的参数:每页显示几条记录($pagesize)和当前是第几页($page)。
有了这两个参数就可以很方便的写出分页程序,我们以MySql数据库作为数据源,在mysql里如果要想取出表内某段特定内容可以使用的 T-SQL语句:select * from table limit offset,rows来实现。这里的offset是记录偏移量,它的计算方法是offset=$pagesize*($page-1),rows是要显示的记录条数,这里就是$page。也就是说select * from table limit 10,10这条语句的意思是取出表里从第11条记录开始的20条记录。
代码如下 | 复制代码 |
class PageView{ $this->totalNum = $count;//总记录数 $this->hasNextPage = $this->pageNo >= $this->pageCount ?false:true; }else if($this->pageNo > $this->pageCount - 4){ /*** "; if(!empty($pageList)){ if($this->pageCount >1){ if($this->hasPrePage){ $pageString = $pageString ."jsFunction . "(" . ($this->pageNo-1) . ")">上一页"; } foreach ($pageList as $k=>$p){ if($this->pageNo == $p){ $pageString = $pageString ."" . $this->pageNo . ""; continue; } if($p == -1){ $pageString = $pageString ."..."; continue; } $pageString = $pageString ."jsFunction . "(" . $p . ")">" . $p . ""; } if($this->hasNextPage){ $pageString = $pageString ."jsFunction . "(" . ($this->pageNo+1) . ")">下一页"; } } } $pageString = $pageString .(" return $pageString; } } ?> |
css
代码如下 | 复制代码 |

使用方法
代码如下 | 复制代码 |
$pageNo = $_GET['pageNo'];
|
下面再介绍一个分页类
代码如下 | 复制代码 |
class SubPages{ |
调用方法
代码如下 | 复制代码 |
require_once("SubPages.php"); |
