我正在使用Bootstrap创建一个响应站点，它包含带有大量文本的嵌套手风琴，当您阅读底部并单击下一个手风琴时，大量文本会折叠起来，我留在页面底部。
我从Bootstrap accordion, scroll to top of active (open) accordion on click?找到了这个有用的代码，但是它仅滚动第一级。 当我单击嵌套的手风琴时，它滚动了两次，滚动的位置也不完美。 我在上面段落中提到的链接中添加了以下脚本。
$(document).ready(function(){
$('.panel-collapse').on('shown.bs.collapse', function(e) {
var $panel = $(this).closest('.panel');
$('html,body').animate({
scrollTop: $panel.offset().top
}, 500);
});
});

尝试此操作，添加e.preventDefault()和e.stopPropagation()以防止双击。
$('.panel-collapse').on('shown.bs.collapse', function(e) {
e.preventDefault();
e.stopPropagation();
var $panel = $(this).closest('.panel');
$('html,body').animate({
scrollTop: $panel.offset().top
}, 500);
});
