那些遇到过的问题

用于比较和保存项目的jQuery多列表解决方案

Rép*_*pás 3 html javascript css jquery drag-and-drop

我正在制作一个可以比较和列出项目的工具.我想给它们制作动画,使它们看起来很酷.请帮我解决实施中的一些问题.有很多问题因此我对每个问题单独提出了一个问题.

问题1 mouseout事件绑定

如果我选择一个项目并将其拉到list1 - list2 - list1,有时会关闭覆盖面板.

问题2单击事件绑定

如果我将一个元素推送到list1,将其放到列表中并单击另一个列表,列表将更接近.点击返回list1后,它会动画3次而不是1次.

发行3个占位符

如何将占位符放到列表中,更好地重新排列和更容易理解交叉删除(列表以列出拖放和项目到列表)

问题4动画平滑度

如何让动画变得更流畅？你怎么看待这件事？

问题5优化

您如何看待,如果我优化代码,它会在浏览器中更快一些吗？你能给我一些建议吗？

发布其他6个想法

如果你有一些一般的想法,我也会欢迎他们.下载它,根据需要使用它,我正在为我女朋友的网站制作它.

你可以在这里检查代码 - jsFiddle,或:

看起来你正试图重新发明轮子并使所有东西过于复杂,以便看起来很性感,但实际上,这可能会让你的用户疯狂.

从我们的(stackoverflow)结束来看,这是一大堆代码,它们非常特定于您要尝试的内容,但我们只需要查看一个区域并提供帮助.

看看jQuery Sortable:http://jqueryui.com/demos/sortable/#connect-lists.这是一个非常干净但很好看的例子,当然可以用一些jQuery CSS动画进行爵士乐.所有浏览器的性能都非常好,您会发现它更容易维护.
