[100分]一道难题!!!谁能把Yahoo新邮各技术扒下来!!!(为JS Fans们做贡献!!!)

Question

呵呵,技术多多,越看越喜欢......
JS Fans 的天堂,丝毫不输OutLook界面....

Answer 1

看一些开源的有关是如何现实。以鱼不如以渔。csdn就不少呀
-----------------------------------------------
don't wrroied,be happy! 有问题[email protected]交流

Answer 2

要扒的话，HOTMAIL的LIVE邮箱，GMAIL的一并扒了吧，都比较NB

Answer 3

自己学吧,多想,多体会,多实践,一定要扎实
其实这些代码的语法很简单
但是难的是dhtml
个人觉得看这些复杂代码会降低自己的自信

Answer 4

/*
原来Yahoo的Javascript用了混淆器啊......
超级难理解啊....这段就是里面很NB的transparent_attch技术,
按一个钮,直接选文件....
可惜混淆得乱七八糟的,没一句备注...谁看得懂哦....

Answer 5

混淆器,很简单,就是把
function UploadAction(filename,fileType,fileSize){}
/*
上面代码很容易读吧,变为:
*/
function ad(aa,ab,ac){}同样还是原代码,逻辑依然通顺,你还看得懂不................?!这就是Javascript保护自己的方法.............

Answer 6

用firefox，不过，用了混淆器，看不懂！！！！！！

Answer 7

还是放弃去扒别人的代码，要是真想得到一个，还不如自己去仿造，如果个人认为要走捷径，那么仿造的时间可能远远少于自己弄明白Yahoo的js内幕!我们要耻于偷盗，用于借鉴优点/亮点
