我的目标是创建一个响应式页面,其中包含用户可以浏览的 div 列表。我需要使用无限滚动的服务器端分页。我还希望能够对列表应用过滤器和排序。我一直在寻找不同的解决方案并遇到(http://isotope.metafizzy.co/),它看起来非常适合我想要的东西,但是,在文档中它建议不要同时使用过滤和无限滚动。
相反,我在我的项目中实现了infinite-ajax-scroll(https://github.com/webcreate/infinite-ajax-scroll)插件,并决定不使用ajax进行归档和订购,以免过度复杂化(并且由于有限的 ajax / jquery 知识)。但是这不起作用,会发生什么是页面加载了正确的过滤器,但是当第二个页面加载时,过滤器不再应用。如何通过过滤器$cat
使其滚动?
以下是我到目前为止所拥有的。
$cat = (isset($_GET['cat']) ? urldecode($_GET['cat']) : '');
$page = (int) (!isset($_GET['p'])) ? 1 : $_GET['p'];
$start = ($page * $pagelimit) - $pagelimit;
$limit = $pagelimit*$page;
//get total number of discounts for search
$total_items = Stuff::countItems($cat);
if( $total_items > ($page * $limit) ){
$next = ++$page;
}
//get items
$items = Stuff::getItems($cat, $sortby, $dir, $start, $limit);
if(!$items){
header('HTTP/1.0 404 Not Found');
echo 'Page not found!';
exit();
}
