当我在javascript中使用scrollto函数时，它什么也不做（甚至在控制台中也没有任何错误）！我正在创建一个在线商店，但是会带您进入另一个页面，因此您总是回到顶部。我用javascript找出了顶部下方有多少像素，然后将其存储在cookie中，当您返回首页时，它将检查cookie，如果有，它将在您尝试时使您失望它，它不起作用！这是我的代码：
<?php
session_start();
include 'db.php';
//unset($_SESSION['products']);
//unset($_SESSION['Abby']);
# $_SESSION['name'] $_SESSION['price'] $_SESSION['descrtion'] $_SESSION['img-ar']
/*unset($_SESSION['name']);
unset($_SESSION['price']);
unset($_SESSION['descrtion']);
unset($_SESSION['img-ar']);*/
?>

如果我把它放在最下面，它的世界工作原理，但是现在我只在页面底部使用滚动功能，它可以正常工作:)！ 😁
