我有 4 個引導手風琴都倒塌了。從導航鏈接單擊時（[href="#headingTwo"] 等...]，我只需要展開參考的手風琴。[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......當然可以將它簡化為一個函式？
// 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。
uj5u.com熱心網友回復：
看起來您的錨點共享同一個類.js-scroll-trigger，您可以將點擊處理程式分配給所有它們，在處理程式中，您將從錨點獲取目標手風琴項href，它是id手風琴項的，然后您可以觸發click處理程式如下所示的專案按鈕。
href包含手風琴標題id，元素包含button觸發展開/折疊的第一個子元素
