Magento Validate Form Only Certain Fields

Question

I have a function to validate all fields in a form:

validateForm: function() {
    var validator = new Validation(this.form);
    validator.validate();
}

There are two controls. First control need to validate only a,b,c fields. Second control need to validate only d,e,f fields. How can I achieve this?

Solution

To validate only a certain field, you can use:

Validation.validate(document.getElementById(id));
