所以无论如何.我有一个div,overflow: auto并经常流过,所以滚动条出现.然后我有一个div,position: fixed并位于内容之上div.
现在,当我div在html主体本身上有一个固定位置时,当我将鼠标放在上面时,我可以用滚轮滚动文档div.上述不太幸运div.
有没有办法滚动div"通过"固定位置的?
我注意到,即使在固定div上方捕捉滚动事件也不容易; 除非固定的div本身是可滚动的,否则不会触发该事件.
我在这里做了一个简单的jsFiddle ,为了您的方便,我尝试了所有的JavaScript.
编辑:我需要使用固定的div保留其他鼠标功能,因此关闭指针事件不是我的解决方案.
我有一个jQuery UI可排序列表.我试图让它在移动设备上运行.我使用了触摸打孔解决方法.为了滚动,我必须停用可排序的功能,我已经完成了,并且在列表元素的taphold上激活可排序的功能.这工作正常,但问题是我想在taphold上允许对元素进行排序.现在它只是这样工作:taphold元素(taphold停止)然后我必须再次点击它以排序.

max = max / 2;
