Bootstrap 手风琴防止在 asp.net 回发时崩溃

我有一个引导手风琴，我尝试在回发时重新打开最后打开的窗格，就像有人单击我页面上的保存按钮一样。我找到了这个解决方案：在页面刷新/导航时保留 Twitter Bootstrap 折叠状态

但我无法对此发表评论，因为我作为用户没有足够的积分。

由于某种原因我无法使该功能工作：

//when a group is shown, save it as the active accordion group
$("#applicant-accordion").bind('shown', function () {
    var active = $("#applicant-accordion .in").attr('id');
    $.cookie('activeAccordionGroup', active)
});

我正在尝试在 FireBug 中测试它，但我从未到达 var active 的行。它停在 $("#applicant-accordion).bind 行。自从我的 jQuery 版本为 1.7.2 以来，我尝试将 .bind 更改为 .on

我很茫然，希望你能指导我找到解决方案。我正在 ASP.NET 中构建它。

<script src="../Scripts/jquery-1.7.2.js" type="text/javascript"></script>
<script src="../Scripts/bootstrap/js/bootstrap.js" type="text/javascript" />
<link href="../Scripts/bootstrap/css/bootstrap.min.css" rel="stylesheet" type="text/css" />
<script src="https://raw.github.com/carhartl/jquery-cookie/master/jquery.cookie.js" />

<script type="text/javascript">
    $(document).ready(function () {
        var last = $.cookie('activeAccordionGroup');
        if (last != null) {
            //remove default collapse settings
            $("#applicant-accordion .panel-collapse").removeClass('in');
            //show the account_last visible group
            $("#" + last).addClass("in");
        }
    });

    //when a group is shown, save it as the active accordion group
    $("#applicant-accordion").on('shown', function () {
        var active = $("#applicant-accordion .in").attr('id');
        $.cookie('activeAccordionGroup', active)
    });

</script>

    <div class="accordion" id="applicant-accordion">

        </div>
    </div>

只是发布我的解决方案：

添加了一个隐藏字段：

<asp:HiddenField ID="hfAccordionIndex" runat="server" />

页面底部的 JavaScript 确保 DOM 具有元素：

<script type="text/javascript">
    $(document).ready(function () {
        var last = $('#<%= hfAccordionIndex.ClientID %>').val();
        if (last != null && last != "") {
            //remove default collapse settings
            $("#applicant-accordion .collapse").removeClass('in');
            //show the account_last visible group
            $("#" + last).collapse("show");
        }
    });

    //when a group is shown, save it as the active accordion group
    $("#applicant-accordion").on('shown', function () {
        var active = $("#applicant-accordion .in").attr('id');
        $('#<%= hfAccordionIndex.ClientID %>').val(active);
    });
</script>
