从 nav-link 滚动到手风琴并打开它

Question

我有 4 bootstrap 个手风琴都倒塌了。从导航点击时 link （[href="#headingTwo"] 等...] 我只需要展开引用的手风琴。[ 如果点击另一个导航 link ]

所以下面的代码有效，但我重复了 4 次....当然可以将它简化为一个函数吗？

// accordion 1
$('a.js-scroll-trigger[href="#headingTwo"]').on('click', function() {
  document.getElementById("collapseTwo").classList.add("show");
});

// accordion 2
$('a.js-scroll-trigger[href="#headingThree"]').on('click', function() {
  document.getElementById("collapseThree").classList.add("show");
});

// accordion 3
$[...]

// accordion 4
$[...]

非常感谢。

看起来您的锚点共享相同的 class .js-scroll-trigger，您可以将点击处理程序分配给所有锚点，在处理程序中您将从锚点的 href，它是手风琴项目的 id，那么你可以触发项目按钮的 click 处理程序，如下所示。

href 包含手风琴 header id，元素包含第一个 child 触发 expand/collapse[ 的 button =20=]

<h2 class="accordion-header" id="headingOne">
  <button class="accordion-button" type="button" data-bs-toggle="collapse" data-bs-target="#collapseOne" aria-expanded="true" aria-controls="collapseOne">
    Accordion Item #1
  </button>
</h2>

$(function() {
  $("a.js-scroll-trigger").on("click", function() {
    var target = $(this).attr("href");

    $(target).find("button").trigger("click");
  });
});
