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
。
const container = document.querySelectorAll(".table-responsive")[0]; container.addEventListener("wheel", function (e) { if (e.deltaY > 0) { container.scrollLeft += 100; e.preventDefault(); } else { container.scrollLeft -= 100; e.preventDefault(); } });
.table-responsive::-webkit-scrollbar { width: 0 !important; } .content { width: 100%; height: 250px; display: flex; justify-content: center; align-items: center; font-size: 3em; }

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。
