從導航鏈接滾動到手風琴並打開它

Question

我有 4 個自舉手風琴都倒塌了。 從導航鏈接單擊時（[href="#headingTwo"] 等...] 我只需要展開引用的手風琴。[如果單擊另一個導航鏈接則關閉它]

所以下面的代碼有效，但我重復了 4 次……它肯定可以簡化為一個 function 嗎？

// 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
$[...]

提前謝謝了。

看起來你的錨點共享相同的 class .js-scroll-trigger ，你可以將點擊處理程序分配給所有這些，在處理程序中你將從錨點的href獲得目標手風琴項目，它是手風琴項目的id , 那么你就可以像下面這樣觸發項目按鈕的click處理程序。

href包含 accordion header id ，該元素作為第一個子元素包含一個觸發展開/折疊的button

<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"); }); });
