我有一个项目 A、B、C、D、E 的列表。您单击这些列表项之一的每个项目都有一个引导程序类“折叠”，它显示一个带有文本的 div。这一切正常。但是，您必须再次单击列表项以折叠包含文本的 div。
我试图确保单击列表项时，所有其他开放式 div 都会立即关闭。
我发现了一些提到使用“data-parent”的东西，但如下面的代码片段所示，这不起作用。要查看问题，请查看代码段并展开代码段。
要复制我的问题，这些是步骤：
我试图确保您只看到与您单击的 div 的 ID 相关的文本。

</html>你可以用 jquery 来做到这一点，
<script type="text/javascript">
$(document).ready(function(){
$('[data-toggle="collapse"]').click(function(event) {
if ($('.collapse.in').length > 0) {
$('.collapse.in').collapse('hide')
}
});
})
</script>
在data-toggle="collapse"点击，在列表项手段点击，这是打开了所有的div（与他们的。在类）接近与合拢功能。
