固定条形脚本使幻灯片播放＆＃34;跳跃＆＃34; - 如何删除？

Question

我找不到更好的因为它是我网站的特定错误，我会提供一个链接来查看它和他的代码。

问题是当我滚动时，有一个脚本当条形触摸浏览器的顶部时，条形图将保留在那里，但这会使幻灯片显示跳跃并且条形图会切割幻灯片的一部分。 / p>

＆＃13;

栏的css是＆＃34;邮件2＆＃34;，幻灯片是＆＃34;滑块＆＃34;和＆＃34;控制＆＃34;。

希望有人可以提供帮助。

Answer 1

当您应用.fixed时，您将从流程中取出菜单元素。这是因为它从position: relative更改为position: fixed。这就是为什么它下面的元素跳了100px。要完成您所需的效果，您需要补偿丢失的100px。

选项1

您可以将margin-top应用于以下#slider元素：

if ($(window).scrollTop() > h) {
   $('.mail2, .optimize').addClass('fixed');
   $('#slider').css('margin-top', '100px');

} else {
  $('.mail2, .optimize').removeClass('fixed');
  $('#slider').css('margin-top', '0px');
}

选项2

您可以在流程中添加100px高度的元素。

在您的HTML中，将其添加到.mail2元素

下方

<div id="menu-block" style="height: 100px; display: none;">

并将其添加到您的JS：

if ($(window).scrollTop() > h) {
  $('.mail2, .optimize').addClass('fixed');
  $('#menu-block').css('display', 'block');

} else {
  $('.mail2, .optimize').removeClass('fixed');
  $('#menu-block').css('display', 'none');
}

在这种特殊情况下，两种方式都是一样的。在其他情况下，只有一种技术是合适的。希望这有帮助！

Answer 2

考虑到条形是100px的固定高度，您可以添加如下规则：

.fixed + #slider {
  padding-top: 100px;
}

或者如果其他页面具有更多动态布局，您可以使用.fixed + *

Answer 3

这是因为只要你成为position:fixed它就不再占用页面上的空间，所以它下面的内容会跳起来填补空间。

我过去曾经遇到过这种情况，而我的解决方案是在另一个div下面修复一下这个问题。它需要与将要固定的div相同的高度。将其设为display:none，然后在切换要修复的栏时将其更改为display:block，这样当固定栏停止占用页面空间时，它就会出现。这应该阻止它跳跃。
