如何将Java正则表达式转换为javascript正则表达式

Question

I will like to translate the Java Regex

(\\\p{Upper}{2})(\\\d{2})([\\\p{Upper}\\\p{Digit}]{1,30}+)

to JavaScript Regex. I tried

([A-Z]{2})([0-9]{2})([A-Z][0-9]{1,30}+)

This translation wouldn't compile. Any help will be highly appreciated.

Answer 1

You have separated last [\\\\\\p{Upper}\\\\\\p{Digit}] into [AZ][0-9] but it should be [A-Z0-9]

Just try with:

([A-Z]{2})([0-9]{2})([A-Z0-9]{1,30}+)

You can also replace 0-9 with \\d , so:

([A-Z]{2})(\d{2})([A-Z\d]{1,30}+)
