Not sure what you mean by "stubbing" here, but regular expressions are
pretty quick. If you supply the set of values as a string using a
delimiter (a space seems appropriate here), you can use something very
similar to the standard "hasClass" function:
var checkValid = (function() {
var validSet = "V30000 B47242 V54000";
return function(val) {
return RegExp('^|\\s' + val + '\\s|$').test(validSet);
}
})();
alert( checkValid('V54000') );
To make the validSet more accessible for initialisation, you might do:
var checkValid = (function(validSet) {
return function(val) {
return RegExp('/^|\\s' + val + '\\s|$').test(validSet);
}
})("V30000 B47242 V54000");
To change the set of valid values, replace the string in the call.
The advantage here is that you can put pretty much any space-delmited
value in the set of valid values and it will "work".
