Jquery画廊式的fancybox

Jquery gallery like fancybox

本文关键字:fancybox Jquery      更新时间:2023-09-26

我正在构建自己的图像库,就像fancybox一样。

请参阅:http://snabbdesign.com/stack/stack.html

我在淡出和进入#gallery时遇到了一些问题。有时背景(#gallery)会在图像之前淡出。

此外,有时.gallery_image不会像它应该的那样居中。

请帮忙!

1)这对我来说不会发生,但如果发生了,我建议你看看.requeue()

2) 使用.outerHeight()和.outerWidth()代替.height()与.width()
