Question

I am using regex to verify that a string only contains alphabets and spaces. Regex is defined as

var regex = /^[A-Za-z ]/;

but even if I am testing it with a string “X,” , it is giving a true result.

What is the error here?

Answer 1

^[A-Za-z ] only matches one character. and ^ means the start of the string. To accomplish what you want, use:

+ – This means match one or more. Alternatively you can use:

* – Which means match zero or more.

But I think you’re better off with the first one (+). Another thing is, match for the whole string. This means you have to search from the first to the last character.

$ – This means match the end.

Your code should be like this:

var regex = /^[A-Za-z ]+$/;
