我有一个这样写的手风琴

                <button class="accordion-button collapsed" type="button" data-bs-toggle="collapse" data-bs-target="#editTournamentAccordion" aria-expanded="false" aria-controls="editTournamentAccordion">
                    Card title
                </button>
            </h2>
            <div id="editTournamentAccordion" class="accordion-collapse collapse" aria-labelledby="editTournamentAccordionHeading" data-bs-parent="editTournamentAccordionWrapper">
                <div class="accordion-body">
                    <iframe class="w-100" style="height: 1024px;" src="www.example.com"></iframe>
                </div>
            </div>
        </div>
    </div>
    </body>
</html>

当我第一次点击 Accordion 标题时，accordion 不会打开并且会抛出以下异常

未捕获的 TypeError：在未实现接口 Element 的对象上调用了“querySelectorAll”。选择器引擎.js:18:59

知道原因吗？据我所知，这是我必须编写的最少代码以使错误出现

标签： bootstrap-5 bootstrap-accordion

【解决方案1】：

TLDR：data-bs-parent 属性中缺少 #。

根据Bootstrap documentation，data-bs-parent 接受一个

选择器 | jQuery 对象 | DOM 元素

当您为属性传入data-bs-parent="id" 时，它是纯文本，因此不属于任何类别。结果你得到了Uncaught TypeError: Illegal invocation

工作示例：

<!DOCTYPE html>
<html>
    <head>
        <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta3/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-eOJMYsd53ii+scO/bJGFsiCZc+5NDVN2yr8+0RDqr0Ql0h+rP48ckxlpbzKgwra6" crossorigin="anonymous">

    </head>
    <body>
    <div id="editTournamentAccordionWrapper" class="accordion accordion-flush">
        <div class="accordion-item">
            <h2 class="accordion-header" id="editTournamentAccordionHeading">
                <button class="accordion-button collapsed" type="button" data-bs-toggle="collapse" data-bs-target="#editTournamentAccordion" aria-expanded="false" aria-controls="editTournamentAccordion">
                    Card title
                </button>
            </h2>
            <div id="editTournamentAccordion" class="accordion-collapse collapse" aria-labelledby="editTournamentAccordionHeading" data-bs-parent="#editTournamentAccordionWrapper">
                <div class="accordion-body">
                  Card Body
<!--                    <iframe class="w-100" style="height: 1024px;" src="www.example.com"></iframe>-->
                </div>
            </div>
        </div>
    </div>
    <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.0-beta3/dist/js/bootstrap.bundle.min.js" integrity="sha384-JEW9xMcG8R+pH31jmWH6WWP0WintQrMb4s7ZOdauHnUtxwoG2vI5DkLtS3qm9Ekf" crossorigin="anonymous"></script>
