Validation check on Mobile number in C# and JavaScript

Question

I am trying to do a validation check on mobile number from both C# code and Javascript.

Following should be validated OK:

• Length equal to 5 or 8+
• Can start with +XXxxxx
• Can start with 00xxxxxxx

I tried using:

C# code:

@"(^((([0-9]{5})|((\+[0-9]{2})[0-9]+)|((00[0-9]{2})[0-9]+))|((([0-9]{8,})|((\+[0-9]{2})[0-9]+)|((00[0-9]{2})[0-9]+))))$)"

JavaScript:

/^((([0-9]{5})|(((00[0-9]{2})|(\+?[0-9]{2}))[0-9]+))|(([0-9]{8})|(((00[0-9]{2})|(\+?[0-9]{2}))[0-9]+)))$/

With these expressions I am able to validate for 1st and last requirement but not the 2nd one (+XXxxxx).

Please help me out on this issue.

use the OR option in the regular expression
