Validate an address field with javascript

I'd like to validate a street address using javascript. The address must be adhere to a Address 12 like format where it begins with one or more characters, followed by a space and then followed by at least one digit.

I'm using the following regexp:

(/[a-zA-Z+\s?\d+$]/.test(field)

and various modifications of these, but is not working well. How can i re-write to be correct?

Thanks a lot.

You are using [] which denotes character class. Only one out of many characters defined in it will be matched.

In your case it's matching only A.

You will have to use /\w+ \d+/ which means Any number of characters space one or more digits

You seem to be mixing bracketed character sets with other regex commands, such as optional and repeating. Something like this would match a word followed by a space by a number:

/^[a-zA-Z]+\s[0-9]+$/.test(field_value)

That said, I don't know any address format that has a single word followed by a number, without allowing for, for example, multiple words in the street name. Which could be achieved like this:

/^([a-zA-Z]+\s)+[0-9]+$/
