使html元素在滚动过去时保持原位
原标题:Make html element stay in place when scrolled past

如何使html元素在滚动到某个位置之前不会固定?因此,当用户滚动时,它将处于正常位置,但在用户滚动过去后,它不会离开屏幕?

问题回答

将一个监听器附加到onscroll事件,如果scrollTop>大于元素的Y位置,则将其设置为position:fixed

请查看jQuery Scrollfollow插件。我使用它来方便地实现这种效果。

您只需在您想要查看的元素上调用它:

<script type="text/javascript">
        $(  #example  ).scrollFollow();
</script>

可以配置放松、位置和其他参数。
