我正在為我準備的網站使用 Bootstrap。由於溢出滾動條看起來很糟糕,我用 CSS 隱藏了它,並嘗試透過 JavaScript 用滑鼠滾輪滾動分頁。
當我使用下面給出的程式碼時,頂部的程式碼可以工作,但底部的程式碼卻不能。當我在 JavaScript 程式碼中給出 [0,1] 作為索引值時,這次底部的索引值起作用,但頂部的索引值不起作用。如何使其在同一頁面的兩個分頁上工作?據我從研究中了解到,我可能需要使用 let
或 var
變數而不是 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
取得該類別的所有元素,然後循環遍歷它們以向每個元素新增一個事件偵聽器。
