使用方法:
实例化一下这个page类,
$list = new Page(每页多少条数据,数据总量,当前页,用来构造分页的数组,每个分页的链接 ,显示分页的类型,后缀 );
比如 $list = new Page(10,1000,1,10,’/zjjz/’,2,’.html’);
echo $page = $list->subPageCss2();
就会显示:
当前第1/100页 [首页] [上页] 1 2 3 4 5 6 7 8 9 10 [下页] [尾页] 每个连接就是 /zjjz/1.html,/zjjz/2.html…….
可以根据直接需要,来组合这个每个分页的链接,实现伪静态。
而ajax分页,就是
$list = new Page($pagesize,$areaAllNumber,$current_page,10,”,3);
$url = $val1.’,’.$val2;//这个就是你要触发的js函数中要传递的值,
$page = $list->subPageCss3(‘checkProducts’,$url);//第一个参数就是要触发的js函数。从而达到ajax分页的效果。
还有一个subPageCss1是 共4523条记录,每页显示10条,当前第1/453页 [首页] [上页] [下页] [尾页] 此种简单样式,也支持伪静态。 |
