滚动到选定手风琴按钮的顶部

Question

我现在有个“手风琴型”片段。它打开按钮下面的内容，然后再次关闭它。因为内容相当长，并且小部件只能在手机上显示，所以让站点滚动到按下的按钮是很有用的，这样用户就可以从顶部滚动到打开的div的底部。

现在，内容unfolds本身位于页面不可见的部分。

这是密码

​

jQuery(function() {
  jQuery('.ss_button').on('click', function() {
    jQuery('.ss_button.active').not(jQuery(this)).removeClass('active')
    jQuery(this).toggleClass('active');
    jQuery('.ss_content').not(jQuery(this).next('.ss_content')).slideUp('fast');
    jQuery(this).next('.ss_content').slideToggle('fast');
  });
  jQuery('.ss_content').eq(1).show();
});

#ss_menu {
  width: auto;

.ss_button {

Answer 1

您只需将内容的height设置为250px (或您喜欢的任何内容)，并将overflow用作auto

这样，您的content就可以成为内容div中的scrollable，而不需要用户成为整个page的scrolling。
