呵呵，看到有人建议多搞点jquery, 我也建议多搞点mootools.
我个人觉得mootools之强悍已经无法用言语形容了，实力是强到偶想哭。
现贴一段我写的基于mootools.r820的 Native Date, 可以按照php date函数的规则分析和输出日期。
复制内容到剪贴板
代码:
Native(Date);
Native.setFamily({'date': Date});
Date.Names = {
Apm: ['Am','Pm'],
Suffix: ['St','Nd','Rd', 'Th'],
Day: ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'],
Month: ['January','February','March','April','May','June','July','August','September','October','November','December']
}
Date.ShortNames = {}
Date.map = {
Y:{k:'FullYear',l:4},
y:{k:'FullYear', l:2, a: 2000},
m:{k:'Month',l:2, a: -1},
n:{k:'Month',l:2, z:1, a: -1},
