Question

下面是我的代码，但我知道它没有任何问题，因为当它从标签中取出时它可以正常工作。也没有重复的Id，我认为可能导致问题。无论如何，如果有人有任何想法或变通办法那将是伟大的！

<div id="sampleNavbar" class="navbar navbar-static">
    <div class="navbar-inner">

Answer 1

这不是Bootstrap中的错误。发生的事情是，当您的页面加载时，带有scrollspy元素的选项卡将被隐藏。因此，当scrollspy插件尝试在滚动div中找到每个$.position()的{{1}}时，它们会调用return <h4 id="foo">。这就是你滚动时看到闪烁的原因;插件认为你所有的滚动目标都在同一个位置。

如果查看documentation for the scrollspy plugin，您会看到它提到如果您要从DOM中添加或删除元素，则需要调用{top: 0, left: 0}函数以便插件可以重新评估各种滚动目标的位置。

那就是说，你需要做的是等到加载了scrollspy内容的标签，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组合到一个处理程序

中

.scrollspy('refresh')

此外，您需要使用CSS将元素的$(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'); }); } }); });设置为data-offset="300"，而不是在<div id="scrollspy-example">元素上使用position属性：

relative

这是一个有效的jsFiddle演示：

Answer 2

添加：

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

之后：

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

确保在加载此特定选项卡时更新正确的位置。否则，错误的li元素将由scrollspy突出显示，直到您移动/开始滚动，从而导致刷新。 'process'行在标签加载上执行此操作。

Bootstrap scrollspy在标签内不起作用？
