DOJO常用的验证函数

先驱者g

dojo提供了几乎全方位的验证函数，在使用下面的方法之前，要通过类似下面的语句引入dojo的相关库，如
<s cript src="/js/dojo/dojo.js"></s cript>
<s cript type="text/javas cript">
dojo.require("dojo.validate");
dojo.require("dojo.validate.check");
dojo.require("dojo.widget.Dialog");
</s cript>
如果不确定要引入哪些validate，可以在dojo的源文件包的src中寻找一下。

All characters in the format string are treated literally except the following tokens: YYYY - matches a 4 digit year M - matches a non zero-padded month MM - matches a zero-padded month D - matches a non zero-padded date DD - matches a zero-padded date DDD - matches an ordinal date, 1-365, and 366 on leapyear ww - matches week of year, 1-53 d - matches day of week, 1-7
Examples: These are all equivalent to October 19, 2005:
Date Format 2005-W42-3 YYYY-Www-d 2005-292 YYYY-DDD 20051019 YYYYMMDD 10/19/2005 M/D/YYYY 19.10.2005 D.M.YYYY
