的jsfiddle here。 我試圖通過添加和刪除in class來實現。它是第一次工作，當第二次嘗試時，它不是。

Answer 1

面板內，您可以使用button或a元素使用data -attributes來打開其他面板如下：

<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>  

你問了提交，之後提交您的頁面重新加載（和重新加載之前的活動面板未知）：

現在您可以將提交操作設置爲位置哈希：<form id="theform" action="#collapseThree">，請注意，這不會觸發重新加載。之後，你可以打開一個基於位置的哈希面板：

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

對於您設置表單動作爲基於位置的URL form id="theform" action="yourpage.html#collapseThree">可以打開面板時觸發頁面重載，例如情況哈希太：

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

最後，您還可以防止表單形式重裝與e.preventDefault();提交後：

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