Question

I have two validation scripts which work in their own right, but I now want to make a text box validate the content to either be one or the other – in this case an email address or a 10 digit number.

I have the following…

^[a-zA-Z][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]$

^[a-zA-Z0-9]{1,10}$

I want to merge these into a single either/or validation expression.

Answer 1

You can join two or more regex with the | “or” operator

^([a-zA-Z][\w\.-]*[a-zA-Z0-9]@[a-zA-Z0-9][\w\.-]*[a-zA-Z0-9]\.[a-zA-Z][a-zA-Z\.]*[a-zA-Z]|[a-zA-Z0-9]{1,10})$
