DOJO常用的验证函数

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。

isText accepts a parameter, and determines if it is a string

value:

returns:

boolean

 

isInteger(value):

isInteger accepts a parameter, and determines if it is an integer. Note that this returns true is it is string integer, or a number integer.

isEmailAddress(value, allowLocal, allowCruft):

value:

value to test.

allowLocal:

boolean. if true, values such as foo@localhost will return true. allowCruft:

boolean. if true, values such as mailto:[e-mail] and <mailto:[e-mail]> will return true.

returns:

boolean

isEmailAddressList(value, allowLocal, allowCruft):

isEmailAddress determines if a list of potential values are email addresses, with various levels of strictness in its validation.

value:

isValidDate(dateValue, format):

isValidate determines if a date is valid under the specified format, or a default format of MM/DD/YYYY if not is specified.

dateValue:

value to test.

format:

format to test

Accepts many format types, including ISO8601 and RFC3339. 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
