Cannot validate class for a custom attribute when create a product in back-end

[lucbaojang]

I created a custom attribute with the input type for products in the back-end, and add new class for it. It called "validate-custom-attribute".

I also add this javascript codes but when I save product, it is still passed.

How can I validate it?

Validation.add("validate-custom-attribute", "Input not correct", function(v) {
parten=/^(\d.{0,1},{0,1})+$/;
return (parten.test($("gift_dropdown").value));
});

@lucbaojang thank you for contacting us.

• First of all you need to declare a validator. Please use lib/web/mage/validation.js as example.
• Then, specify validator in data-validate attribute. Example: data-validate="{required:true,'validate-greater-than-zero':true}"

Sorry, by "amazing" were you referring to @kokoc or the capability? ;-)
