Question

我似乎无法使工作通俗易懂。我在有时隐藏的div项中有一个导航项。此导航项需要具有工作滚动功能。我不确定问题是否与活动类有关。单击链接时，它不会变为活动状态。滚动到该部分也不起作用。

问题是我缺少一个＃，样式为div data-spy，而活动类属于li标记。

public void Stop()
{
    if(clockPin != null )
    {
        clockPin.Dispose();
    }

    if(dataPin != null)
    {
        dataPin.Dispose();
    }
}

Bootstrap 4 Scrollspy在div中的导航项不起作用
