我正在制作一个可以比较和列出项目的工具。我想为它们设置动画,以便它们看起来很酷。请帮助我解决实现中的一些问题。有多个问题,所以我每个问题都单独提出。
发出1个mouseout事件绑定(bind)
有时,如果我选择一个项目并将其拉到list1-list2-list1,则覆盖面板会关闭。
问题2点击事件绑定(bind)
如果我将一个元素推到list1,将其放到列表中,然后单击另一个列表,该列表将更近。单击返回到list1后,它会动画3次,而不是1次。
问题3占位符
我如何将占位符放置到列表中,这使得更好地重新排列并更容易理解交叉放置(对于列表到列表拖放以及项目到列表)
问题4动画平滑度
如何使动画更流畅?你怎么看待这件事?
问题5优化
您认为,如果我稍微优化一下代码,它将在浏览器中更快吗?你能给我一些建议吗?
提出6个其他想法
如果您对此有一些一般性的想法,我也欢迎您。
下载它,并根据需要使用,我正在其女 friend 网站上进行制作。

最佳答案
似乎您是在尝试重新设计轮子,并使所有事情都变得过于复杂,以使外观看起来很性感,但实际上,这可能会使您的用户发疯。
从我们的(stackoverflow) Angular 来看,这是很多代码,这些代码非常具体地与您要执行的操作有关,但是我们要做的只是很多事情,我们需要着眼于一个 Realm 并提供帮助。
看一下jQuery Sortable:http://jqueryui.com/demos/sortable/#connect-lists。这是一个非常干净但外观漂亮的示例,可以肯定地用一些jQuery CSS动画进行了修饰。在所有浏览器上的性能都非常好,您会发现它更易于维护。
