Answer 1

在面板中，您可以使用button 或a 元素通过使用data 属性打开另一个面板，如下所示：

<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>    

您要求提交，在提交后您的页面重新加载（并且重新加载之前的活动面板是未知的）：

现在您可以将提交操作设置为位置哈希：<form id="theform" action="#collapseThree">，注意这不会触发重新加载。之后，您可以根据位置哈希打开面板：

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

对于触发页面重新加载的情况，例如将表单操作设置为 URL form id="theform" action="yourpage.html#collapseThree"> 时，您也可以根据位置哈希打开面板：

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

最后你还可以使用e.preventDefault();防止表单重新加载：

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