If all you are trying to do is tell if the input value is a string of
spaces, you can test it using the search() method:

function isAllSpaces(inputValue) {

  if(inputValue.search(/^\s*$/) != -1) {
    // the string contains just spaces or is empty
    return true;
  } else {
    // valid input
    return false;
  }

}

This returns true if the string is empty or it is all spaces.  Changing
the * to a + will return true if it is just spaces and false if it is
empty.
