正则表达式检查Actionscript中的日期3 [英] Regular Expression to check Date in Actionscript 3
问题描述
大家好,
我正在Flash Builder 4.6中开发一个应用程序,在我的应用程序中我有TextInput字段来从用户那里获取日期。我想以这种格式得到它:yyyy / mm / dd如2013/09/24
那么,我的正则表达式应该是什么来检查是否提交了上述格式的正确日期? ?
我的textinput字段id是date
我在我的actionscript函数中得到它的价值:
var d_date:String = new String;
d_date = date.text.toString();
现在我想检查这个d_date是否是yyyy / mm / dd格式?
有什么建议吗?
感谢您的帮助...
Hi every one,
I am developing an application in Flash Builder 4.6 and in my Application I have TextInput field to get the date from user. I wanna get it in this format: yyyy/mm/dd like 2013/09/24
So, what should be my regular expression to check if a correct date in the above format is submitted or not??
my textinput field id is "date"
And I am getting its value in my actionscript function like this:
var d_date:String = new String;
d_date = date.text.toString();
Now I wanna check this d_date if it is in yyyy/mm/dd format?
Any suggestions??
Thanks for any help...
推荐答案
我能给出的最好的建议是:不要使用正则表达式。
一定要用一个基本的正则表达式来检查四个-digits斜杠后两位斜杠两位数字;这很简单:
The best suggestion I can give is: don't use a regex for this.
By all means use a basic regex to check four-digits-slash-two-digits-slash-two-digits; thats simple:
^\d{4}/\d\d/\d\d
但不要试图进一步。这真的不值得:检查并转换代码中的实际日期,这很多,很简单!
But do not try to take it any further. It really isn't worth it: check and convert the actual date in code, it is a lot, lot simpler!
