South African ID Number Validate and Get Age and Gender
提问by Dawid van der Hoven
I've researched this but none of the code I use seems to work. South African ID numbers contain date of birth and gender. All I want is it to pull in that information and verify it when their ID number is entered into an input field, preferably in jQuery or javascript
我已经研究过这个，但我使用的代码似乎都不起作用。南非身号码包含出生日期和性别。我想要的只是提取该信息并在将他们的 ID 号输入到输入字段时进行验证，最好是在 jQuery 或 javascript 中
Any help is appreciated,
任何帮助表示赞赏，

You could use Koenyn's regex validation, not so sure how a single-digit number (0-9?) from the input represents the gender but basing on this toolyou provided and David Russell's Using Javascript to validate South African ID Numbers, here's an untested attempt:
您可以使用 Koenyn 的正则表达式验证，不太确定输入中的一位数（0-9？）如何表示性别，但基于您提供的这个工具和 David Russell 的Using Javascript to validate South Africa ID Numbers，这是一个未经测试的试图：
UPDATE 1:After following this thread, What is a South African ID number made up of?, I updated my implementation to include the gender and citizenship tests.
更新 1：遵循此线程后，南非身号码由什么组成？，我更新了我的实施以包括性别和公民身份测试。
UPDATE 2:Forgot to wrap the month number increment id_month + 1within the date string fullDate, updating solution with Dawid's fix.
更新 2：忘记将月份数字增量包装id_month + 1在日期字符串中fullDate，使用 Dawid 的修复更新解决方案。

this is the validation regex we us at our company:
这是我们公司的验证正则表达式：
string IdExpression = @"(?<Year>[0-9][0-9])(?<Month>([0][1-9])|([1][0-2]))(?<Day>([0-2][0-9])|([3][0-1]))(?<Gender>[0-9])(?<Series>[0-9]{3})(?<Citizenship>[0-9])(?<Uniform>[0-9])(?<Control>[0-9])";
as far as using regex, it's really simple http://www.w3schools.com/jsref/jsref_obj_regexp.asp
至于使用正则表达式，它真的很简单 http://www.w3schools.com/jsref/jsref_obj_regexp.asp
