__init_xu 色色js代码库 -- 新手帖代码全部删除,请见谅!!!
今年纯粹是JS学习年,一年大部分时间都在折腾JS,其它后台技术基本没有大的收获...
在学习JS的过程中得到了很多大哥的帮助,让我从JS菜鸟到现在的水平,对JS闭包的疑惑到现在的了解,对我帮助最大的是ALZ老大,小夜,UCREN开发者[小黄],阿旭,天凡,心跳,小白,中山,老白等等....
关于之前的一系列回帖,竟然被大家集体投成新手帖,看来是我太肤浅了... 以后不再写这种新手贴了,源代码全部删除,留下了一个PDF文档,之前发出的代码全部在里面,后期更新的__init_xu 色色js代码库不再在博客上贴出,请见谅!!!
新上传 __xu_init.all.min.js 最新版本的编译版本,支持MD5加密,提供xu.uid()生成唯一值
eo对象新增empty方法,呵呵,循环删除节点就可以了:
