无法使用 Bootstrap 折叠答案

【问题标题】：unable to collapse using Bootstrap Collapse无法使用 Bootstrap 折叠
【发布时间】：2021-12-12 13:09:20
【问题描述】：

我正在开发一个网站，该网站用于使用垂直折叠手风琴显示新闻。我正在使用外部 API 来获取新闻。我只需要一次显示新闻。当我点击第二个新闻标题时，我需要隐藏/折叠第一个新闻描述。同样，当我单击任何新闻时，我希望其余的保持折叠/隐藏，但这不起作用。（见web page snip）

这里是html和JS代码。

JS :

let display = document.getElementById("display");
const xhr = new XMLHttpRequest;

xhr.open("GET", "https://newsapi.org/v2/top-headlines?sources=bbc-news&apiKey=70893d07e43d413faf7813e13df0f8aa", true)

xhr.onload = function () {
    let strHtml = "";
    if (this.status === 200) {
        let newsObj = JSON.parse(this.responseText);
        let newsArticles = newsObj.articles;

        console.log(newsArticles)

        newsArticles.forEach(function (element, index) {      //newsArticle --> an array which contains the news data including the title and description of the news

            let str = `<div class="accordion-item">
            <h2 class="accordion-header" id="heading${index}">
              <button class="accordion-button collapsed" type="button" data-bs-toggle="collapse" data-bs-target="#collapse${index}" aria-expanded="false" aria-controls="collapse${index}">
                ${element.title}
              </button>
            </h2>
            
            <div id="collapse${index}" class="accordion-collapse collapse" aria-labelledby="heading${index}" data-bs-parent="#accordionExample">
              <div class="accordion-body">
                <strong>  ${element.description}</strong>
                <a href="${element.url}" target="_blank" <button type="button" class="btn btn-primary">Learn more</button> </a>
              </div>
            </div>
            
          </div>`

            strHtml += str;        //append news data into strHtml string 
        });
    }
    else {
        console.log("some error")
    }

    display.innerHTML = strHtml;         //to display the news on the page

}

xhr.send();

【问题讨论】：

data-bs-parent="heading${index}" ?
在这里发布您的代码，如果有，错误。没有图片。
用 HTML 和 JS 代码编辑帖子

标签： javascript html twitter-bootstrap

【解决方案1】：

您的手风琴周围需要一个<div> 并带有父 ID：

<div class="accordion" id="accordionExample">

在你的 .collapse 元素中你需要它

 data-bs-parent="#accordionExample"

你已经有了。所以我想这只是缺少的包装器。

这行得通。非常感谢！我刚刚在我的 html 代码中使用了
。
很高兴听到 ;-)
