Hello,
Right now I use this regular expression: /^\d{2}$/
As I understand it, it will match a two digit number that begins and ends with a number, like “24”, “55”, “39” and “10”.
Right now, I’m trying to expand this to allow both 1 and 2-digit numbers that also begins and ends with a number.
So numbers like “3”, “7”, “12” and “45”.
Would I use something like /^\d{1|2}$/
Thanks
/^\d{1,2}$/
You separate the upper and lower bounds with a comma.
Unless the digits are part of a larger expression it would be easier just to check if the number is less than 100.
The value is part of a larger expression, so the comma for the upper and lower values works great.
Thanks both of you!
As I’m working through this form, I now come across a new problem.
Originally I just needed an expression that allowed for exactly only five numerical digits. This worked great /^\d{5}$/
But now, I need an expression that allows for exactly only five numerical digits OR exactly only nine numerical digits.
So now that the numbers aren’t next to each other, I don’t know what to do.
/^\d{5,9}$/ won’t work, because six, seven, or eight digit numbers just won’t work.
Thanks for any help.
One of theese two.
/^\\d{5}$|^\\d{9}$/
/^\\d{5}(\\d{4})?$/
I like the second myself, because I can determine which one it is by the existance of a back reference.
