Regular Expression for alphabets with spaces

This is the better solution as it forces the input to start with an alphabetic character. The accepted answer is buggy as it does not force the input to start with an alphabetic character.

[a-zA-Z][a-zA-Z ]+

Just add the space to the [ ] :

var regex = /^[a-zA-Z ]*$/;

This will allow space between the characters and not allow numbers or special characters. It will also not allow the space at the start and end.

[a-zA-Z][a-zA-Z ]+[a-zA-Z]$
