Question

我希望在向上滚动时（这是仅适用于移动设备的基于html的网站）.profiledetails顶部固定且位置顶部20%。但默认位置将是最高40%。

如果你们看到MIUI个人资料部分，那么更容易理解。

让我举例说明更多细节。默认情况下，.profiledetails从{6}高度（60%）从底部开始向下滚动vh向上移动，当它.profiledetails高度（{{1}然后它会修复。我的确吼了一下

80%

但这不起作用。我不知道为什么。内部vh内容也需要内部滚动。

如果您看到该视频，那么请清楚地了解它如何滚动并修复位置也是内部滚动

Answer 1

问题是卷轴＆＃34;属于＆＃34;到.call-log-area所以事件监听器应该在它上面。

＆＃13;

$('.call-log-area').on("scroll", function() {
  if ($('.call-log-area').scrollTop() > 100) {
    $(".profiledetails").addClass("fixpos");
  } else {
    $(".profiledetails").removeClass("fixpos")
  }
});
