Your regex counts the number of spaces.. Use the following for words (without numbers):

/[a-zA-Z]+/

For splitting use the following:

this.split(/[\s\D]+/).length

The following regex might help you out:

String.prototype.countWords = function(){
    return this.split(/\s+[^0-9]/).length;
}

The ^ negates the characters in the brackets, so all characters are allowed to follow the whitespaces except any numbers.

By the way: here is a good place to test your regex: http://regexpal.com/
