如何使用 JavaScript 選擇 Bootstrap 分頁程式碼中的所有元素?

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 letvar 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。

    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();
        }
      });
    });
