html - Bootstrap Accordion 在尝试使用动态 ID 时不起作用

Question

它不会与 foreach 分配的 ID 一起折叠。

我已经用非动态 ID 尝试过它并且它有效。

<div class="accordion" id="myAccordion">
    @foreach (var item in Model)
    {
        <div class="card">
            <div class="card-header">
                <h5 class="mb-0">
                    <button class="btn btn-link" type="button" data-toggle="collapse" data-target="#@item.Id">
                        @item.Version.Component.Product.Name's @item.Version.Component.Name's @item.Version.ReleaseNumber Version
                    </button>
                </h5>
            </div>
            <div id="@item.Id" class="collapse" data-parent="#myAccordion">
                <div class="card-body">

                </div>
            </div>
        </div>
    }
</div>
</div>

Answer 1

数字 id 不适用于 Bootstrap Accordion (参见 this question )。所以在 id 和 data 目标前加上一个字母。此外，当 @ 符号嵌入到字符串中时，您必须使用括号来标识要执行的代码。

        <div class="card-header">
            <h5 class="mb-0">
                <button class="btn btn-link" type="button" data-toggle="collapse" data-target="#X@(item.Id)">
                    @item.Version.Component.Product.Name's @item.Version.Component.Name's @item.Version.ReleaseNumber Version
                </button>
            </h5>
        </div>
        <div id="X@(item.Id)" class="collapse" data-parent="#myAccordion">
            <div class="card-body">
                Anim pariatur cliche reprehenderit, enim eiusmod high life accusamus terry richardson ad squid. 3 wolf moon officia aute, non cupidatat skateboard dolor brunch. Food truck quinoa nesciunt laborum eiusmod. Brunch 3 wolf moon tempor, sunt aliqua put a bird on it squid single-origin coffee nulla assumenda shoreditch et.

        </div>

正如@terrencep 提到的，您应该在浏览器的页面检查器中查看数据切换的值。
