First, that should be:
addMethod("buga", function(value, element, regex) {
var expression = new RegExp(regex, "g");
return (value.replace(expression,"").length==0);
}
Second, just the same as your initial draft:
someElement: {
required: true,
buga: "[a-z]"
}
But that wasn't the point, rather this:
addMethod("letters", function(value) {
return /[a-z]/.test(value);
}
Then:
someElement: {
required: true,
letters: true
}
That way you give the regex a name and make it reusable. Most
non-trivial regular expressions are write only - you really don't want
to try to read and understand them. So having them in one place only
and with a name is well worth it.
