我正在为我准备的网站使用 Bootstrap。由于溢出滚动条看起来很糟糕，我用 CSS 隐藏了它，并尝试通过 JavaScript 用鼠标滚轮滚动分页。
当我使用下面给出的代码时，顶部的代码可以工作，但底部的代码却不能。当我在 JavaScript 代码中给出 [0,1] 作为索引值时，这一次底部的索引值起作用，但顶部的索引值不起作用。如何使其在同一页面的两个分页上工作？据我从研究中了解到，我可能需要使用 let 或 var 变量而不是 const。

e.preventDefault();

您可以使用
querySelectorAll获取该类的所有元素，然后循环遍历它们以向每个元素添加一个事件侦听器。const containers = document.querySelectorAll(".table-responsive"); containers.forEach(container => { container.addEventListener("wheel", function (e) { if (e.deltaY > 0) { container.scrollLeft += 100; e.preventDefault(); } else { container.scrollLeft -= 100; e.preventDefault(); } }); });
