我还没有找到这个问题的任何解决方案，所以我再问一次，这是上一个问题的链接：jQuery.ScrollTo onAfter settings is not working correct
我正在使用 jQuery.ScrollTo 脚本来垂直滚动到所选图像或下一个图像。（这取决于“演示文稿”类是否附加到我的图像容器）
为此，我创建了两种状态：“演示模式”和“无演示模式”。
当我们通过将全局类“presentation”添加到我的容器“#galleries”中来单击图像时，我将激活演示模式。使用此类“打开”，我可以确定是否必须显示当前图像或滚动到下一个图像。
为了演示模式，我编写了“$(window).scroll”函数。当用户在页面内滚动时，此功能将退出演示模式。
问题：当我在演示模式中使用 .scrollTo 事件时，由于“$(window).scroll”功能，我总是退出“演示”模式。所以，我有全局变量“presentation_mode_stop_scrolling”来阻止它，但这不起作用
这是我的问题：在图片上单击事件后，有时，我的 $(window).scroll 函数删除了我的类“演示文稿”，有什么想法吗？？？
这是演示：http: //jsfiddle.net/qnQSP/12/
这是我的代码：
<div id="galleries">
<div id="pictures-content" class="1"><img src="http://www.sb-designs.co.uk/ckfinder/userfiles/images/free%20web%20hosting.jpg"></div>
