问题描述
我一直有一些问题经常EX pressions。我想验证用户输入时，公交车号码输入。
I have been having some problems with regular expressions. I want to validate user input when a bus number is entered.
例如：37，37A，37S，37A / L，16A / 250，16A / 250K等
Examples: 37, 37A, 37S, 37A/L, 16A/250, 16A/250K etc
常规EX pression我想出了为
The regular expression I came up with is
(^\d{1,3}[A-Z]{0,3})|(^[\d{1,3}[A-Z]{0,3}\/\d{0,3}[A-Z]{0,3}])
据验证37，37A，37S但是当涉及到验证37A / L失败。谁能告诉我在哪里，我错了这个？
It validates 37, 37A, 37S but when it comes to validating 37A/L it fails. Can someone tell me where I am going wrong with this?
注：我使用的是常规的前pression验证的文本框。我把这个在ValidationEx pression。
Note:I am using a regular expression validator for a text box. I have placed this in the ValidationExpression.
推荐答案
没有指定它有问题，因为字符串的结尾。
It was having problem as end of string was not specified.
替换本，
(^\d{1,3}[A-Z]{0,3}$)|(^\d{1,3}[A-Z]{0,3}\/\d{0,3}[A-Z]{0,3}$)
希望这有助于。
Hope this helps.
