我正在使用 Bootstrap“折叠”插件为一长串链接制作手风琴。手风琴体标签包括“折叠”，因此当页面加载时所有组都折叠起来。当您打开一个组并单击一个链接时，它会将您带到一个新页面以查看一些详细信息，然后您单击一个返回链接或浏览器返回以返回到列表。不幸的是，当您返回手风琴时，手风琴又回到了折叠状态，您必须再次打开该组并找到您所在的位置。我预计会有很多这种来回导航，这种行为会令人沮丧。
有什么方法可以保留用户的位置并返回到它，或者只是防止页面重新加载或 javascript 再次触发。
我认为解决方案可能是沿着这些思路，但不确定。 Twitter bootstrap：向打开的手风琴标题添加一个类
您可以通过 cookie 轻松解决此问题。有很多简化的库，比如我在下面的示例中使用的https://github.com/carhartl/jquery-cookie ：
<script src="https://raw.github.com/carhartl/jquery-cookie/master/jquery.cookie.js"></script>
将以下代码添加到脚本部分（#accordion2参考修改后的 twitter bootstrap 示例，我随后列出）
$(document).ready(function() {
var last=$.cookie('activeAccordionGroup');
if (last!=null) {
//remove default collapse settings
$("#accordion2 .collapse").removeClass('in');
//show the last visible group
$("#"+last).collapse("show");
}
});
//when a group is shown, save it as the active accordion group
$("#accordion2").bind('shown', function() {
var active=$("#accordion2 .in").attr('id');
$.cookie('activeAccordionGroup', active)
});
你完成了！这里是http://twitter.github.com/bootstrap/javascript.html#collapse上示例的修改版本，带有可点击的链接，当您返回时 - 最后显示的手风琴组会自动打开

<div class="accordion-group">

jQuery
$(document).ready(function () {
//when a group is shown, save it as the active accordion group
$("#accordion").on('shown.bs.collapse', function () {
var active = $("#accordion .in").attr('id');
$.cookie('activeAccordionGroup', active);
// alert(active);
});
$("#accordion").on('hidden.bs.collapse', function () {
$.removeCookie('activeAccordionGroup');
});
var last = $.cookie('activeAccordionGroup');
if (last != null) {
//remove default collapse settings
$("#accordion .panel-collapse").removeClass('in');
//show the account_last visible group
$("#" + last).addClass("in");
}
});
我尝试了上面建议的技术，它对我有用（有点），但在某些情况下调用 .collapse("show") 似乎会破坏手风琴切换行为。打开第一个面板将使先前打开的面板保持打开状态。我通过添加类“in”来解决这个问题：
$(document).ready(function() {
var last=$.cookie('activeAccordionGroup');
if (last!=null) {
//remove default collapse settings
$("#accordion .panel-collapse").removeClass('in');
//show the account_last visible group
$("#" + last).addClass("in");
}
});
否则，感谢 davidkonrad 让我走上正轨。
谢谢你，它有效。我对其进行了一些修改，以简单地保留特定 DIV 的显示/隐藏状态（而不是特定于在 DIV 列表中仅显示一个 DIV）。
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery-cookie/1.4.1/jquery.cookie.js"></script>
<script language="javascript" type="text/javascript">
function retainDivCollapsedState(nameOfDiv, nameOfHeader) {
// when the div is shown, save a cookie with a value of 'true'
$("#" + nameOfDiv).on('shown.bs.collapse', function () {
$.cookie(nameOfDiv, "true"); // this is a cookie. named the same as the control (poor practice) for brevity
});
// when the div is collapsed, remove the same cookie
$("#" + nameOfDiv).on('hidden.bs.collapse', function () {
$.removeCookie(nameOfDiv);
});
// on page load, show or hide the div (and stylized the header) according to the cookie (if it exists)
var showDiv = $.cookie(nameOfDiv);
if (showDiv != null) {
$("#" + nameOfDiv).addClass("in"); // The div to show
$("#" + nameOfHeader).removeClass("collapsed"); // The header to stylize as expanded
}
};
</script>
<script language="javascript" type="text/javascript">
$(document).ready(
retainDivCollapsedState("divName", "divHeaderName")
);
</script>
另一个可用的选项是使用 url 哈希。
$(document).ready(function () {
var hash = window.location.hash;
if (hash) {
$("#accordion .panel-collapse").removeClass('in');
$(hash).addClass('in');
}
$('#accordion').on('shown.bs.collapse', function () {
var activeId = $("#accordion .in").attr('id');
window.location.hash = activeId;
});
$('#accordion').on('hidden.bs.collapse', function () {
window.location.hash = '';
});
});
谢谢你，发现它很有帮助，但如果你使用的是 Bootstrap 3 和最新的 jquery，这可以工作：
$("#accordion").on('shown.bs.collapse', function()
{
...
});
希望这可以节省其他人一些时间....
好的，伙计们，所以我花了一些时间试图让它发挥作用。主要是因为我发现的所有答案都超级旧且未更新。
这将适用于：
注意：更新到新的 Github 存储库https://github.com/js-cookie/js-cookie的 cookie的使用已更改，例如，而不是$.cookie('name');现在Cookies.get('name');
包括
<script src="https://cdn.jsdelivr.net/npm/js-cookie@rc/dist/js.cookie.min.js"></script>
脚本
$(document).ready(function() {
var last=Cookies.get('activeAccordionGroup');
if (last!=null) {
//remove default collapse settings
$("#accordion .collapse").removeClass('show');
//show the last visible group
$("#"+last).collapse("show");
}
});
//when a group is shown, save it as the active accordion group
$("#accordion").bind('shown.bs.collapse', function() {
var active=$("#accordion .show").attr('id');
Cookies.set('activeAccordionGroup', active);
});
变化：
