YUI 对话框：实例化一个并显示/隐藏多次？或者每次都实例化一个新的？
如果我使用 YUI 来显示一个对话框，我可能希望在一个页面中出现五次，那么最好：
A) 实例化一个对话框，然后多次显示和隐藏它？或者
B）每次显示时都实例化一个新的，然后将其丢弃？
第一个选项似乎会更快。第二种选择似乎需要更少的资源。
想法？
If I was using the YUI to show a dialog which I might want to appear, say, five times in the course of a page, would it be better to:
A) Instantiate one, and then show and hide it several times? or
B) Instantiate a new one each time it's to be displayed, then dispose of it?
First option seems like it'd be faster. Second option seems like it'd require fewer resources.
Thoughts?

如果是我，我会实例化一个并多次展示。
随着时间的推移，您将节省更多资源。当您比较按需创建新对话框所需的资源时，您所说的在内存中保存对话框的资源很小。您的用户还会注意到性能的一小部分提升（考虑到按需创建的时间与使用已有可用的时间相比）。
If it were me, I would instantiate one and show it several times.
You'll save more resources over time. The resources you're talking about to hold a dialog in memory are small when you compare the resources it takes to create new ones on demand. You're users will also notice a small performance gain (given the time to create on demand versus using one that is already available).
