的jsfiddle here。 我试图通过添加和删除in class来实现。它是第一次工作，当第二次尝试时，它不是。

Answer 1

面板内，您可以使用button或a元素使用data -attributes来打开其他面板如下：

<button class="btn btn-default" data-toggle="collapse" data-parent="#accordion" href="#collapseTwo">Open panel 2</button> 
<a class="btn btn-default" data-toggle="collapse" data-parent="#accordion" href="#collapseThree">Open panel 3</a>  

你问了提交，之后提交您的页面重新加载（和重新加载之前的活动面板未知）：

现在您可以将提交操作设置为位置哈希：<form id="theform" action="#collapseThree">，请注意，这不会触发重新加载。之后，你可以打开一个基于位置的哈希面板：

$(window).on('hashchange', function(e) { $(window.location.hash).collapse(); }); 

对于您设置表单动作为基于位置的URL form id="theform" action="yourpage.html#collapseThree">可以打开面板时触发页面重载，例如情况哈希太：

if(window.location.hash) { 
$(window.location.hash).collapse(); 
} 

最后，您还可以防止表单形式重装与e.preventDefault();提交后：

$('#theform').on('submit', function(e){ 
    e.preventDefault(); 
    $('#collapseThree').collapse(); 
});
