下面是我的代码，但我知道它没有任何问题，因为当您将其从选项卡中取出时它工作正常。也没有重复的 ID，我认为这可能是导致问题的原因。无论如何，如果有人有任何想法或解决方法，那就太好了！

这不是 Bootstrap 中的错误。发生的情况是，当您的页面加载时，带有 scrollspy 元素的选项卡被隐藏。因此，当 scrollspy 插件试图在你的滚动 div 中找到$.position()每个的时<h4 id="foo">，它们会调用 return {top: 0, left: 0}。这就是为什么您在滚动时看到闪烁的原因；该插件认为你所有的滚动目标都在同一个位置。

如果您查看scrollspy 插件的文档，您会看到它提到如果您在 DOM 中添加或删除元素，您需要调用该.scrollspy('refresh')函数，以便插件可以重新评估各种滚动目标的位置。

也就是说，您需要做的是等到加载了滚动间谍内容的选项卡，然后调用刷新函数，就像这样。请注意，我还将所有单独的点击处理程序合并到一个处理程序中

$(function(){
    $('.nav-tabs li a').click(function(e) {
        e.preventDefault();
        $(this).tab('show');

        // If we are showing the scrollspy tab, let the
        // plugin refresh itself so it can function properly
        if(this.id === 'scrotab') {
            $(this).on('shown',function(){ 
                $('#scrollspy-example').scrollspy('refresh'); 
            });
        }
    });
});

此外，您需要使用 CSS将元素设置为，而不是在元素上使用data-offset="300"属性：<div id="scrollspy-example">positionrelative

#scrollspy-example {
    position: relative;
}

这是一个有效的 jsFiddle 演示：

添加：

$('#scrollspy-example').scrollspy('process');

之后：

$('#scrollspy-example').scrollspy('refresh');

确保在您加载此特定选项卡时更新正确的位置。否则，scrollspy 将突出显示错误的 li 元素，直到您移动/开始滚动，从而导致刷新。'process' 行在选项卡加载时执行此操作。
