Regular expression for name which accepts alphabets only and space only between two words. no space allowed at the start or at end of the name

Question

I tried this but it is not working

/^[A-Za-z\s]{1,}[\.]{0,1}[A-Za-z\s]{0,}$/

Answer 1

A solution could be ^[a-zA-Z]*?[a-zA-Z]*$

It checks if it starts with a letter, it has an optional space, and checks if it ends with a letter

Answer 2

You can use this regex, which solve your problem:

/^(?:[A-Za-z]+ ?[A-Za-z]+)*$/gm

So, your words are only alphabets and can be separated by only one space.

If you want the words to be separated by several spaces, you can do the following:

/^(?:[A-Za-z]+ *[A-Za-z]+)*$/gm

I use no-capturing groups beacuse of repeated group ( (...)* ).
