Question

我试图弄清楚如何在回发期间保持当前的手风琴窗格打开。我查看了这些帖子，但他们都使用jQuery中的实际手风琴功能，而我只使用css。

使用隐藏字段存储索引介于回发之间

<asp:HiddenField runat="server" ID="hdnIndexValue1" Value="-1" />

<script type="text/javascript">
    $(document).ready(function () {
        $(".eventContent").hide();
        var index = parseInt(document.getElementById("hdnIndexValue1").value);
        $('.eventContent:eq(' + index + ')').show();

        $('.eventHeader').click(function () {
            $(this).toggleClass('active-header').toggleClass('inactive-header');
            $(this).next().slideToggle().toggleClass('open-content');
            var index = $(".eventHeader").index(this);
            document.getElementById('hdnIndexValue1').value = index;
        });
    });
</script>

如何仅使用样式将当前的手风琴保持在回发状态？
