jQuery插件实现图片展开效果,jquery.gallery。仿腾讯QQ空间说说图片展示效果。

时间:2022-08-22 10:06:07

 

公司的项目http://www.umfun.com/,有个说说的页面(和腾讯QQ空间说说一样),里面有个发表图片功能,上传完图片,需要点击展开的效果。

当时手里面事情比较多(公司就我一个前端),忙不过来,就用插件来实现了,试了fancyBox、lightbox等jQuery插件。插件都满足不了项目各种奇怪的需求,但是时间有限,只能先凑合了。、

项目上线后,最近时间比较充足,我就想把写个插件封装一下。毕竟人家的插件比较臃肿,修改起来麻烦,同时免得以后又是各种修改,还是根据公司的项目需求写比较好。。。

 

效果预览,如果下图所示:

PS:

1、基本功能实现了,没搞什么选项设置,有时间再扩展,现在已经满足需求了。。

2、公司的项目只需要兼容IE7+兼容就可以。so。。。IE6就没考虑了。。
