推荐答案
我有同样的问题到触发崩溃切换的链接）
href =＃更改为 href =javascript：void ）;，它工作的很好（翻转崩溃，没有任何滚动到顶部）
I had same problem (jump to the top on click to the link which was triggering the collapse toggle)
the href="#" was changed to href="javascript:void(0);" and it is working great (toggling collapse without any scrolling to the top)
