我有一个无限滚动的页面,当用户的浏览器缩放为 100% 时可以正常工作。如果用户放大或缩小页面(即不是 100%),滚动最终会中断,页面将停止检索记录,即使还有更多记录需要获取。
我该如何纠正?

<body>

这是test2.php:
<?php
if(isset($_GET['lastid'])){
$counter=addslashes($_GET['lastid']) + 1;
$total=$counter+25;
for($counter; $counter <= $total; $counter += 1){
echo "\n".'<div class="postitem" id="'.$counter.'">Post no '.$counter.'</div>';
}
}
?>
