Let Magento's validate verify hidden field

Object.extend (Validation, {
    Isvisible:function (Elm) {
        return true;
    },
    Insertadvice:function (Elm, advice) {
        Advice contains the div that's would normally be inserted.
    }
});

But after the validation.js is loaded, the code is executed. I'm rewriting it according to my needs.

Object.extend (Validation, {
    Isvisible:function (Elm) {
        while (elm.tagname! = ' BODY ') {
            if (!$ (Elm). Visible () &&!$ (Elm). Hasclassname (' Validate-must ') return false;
            Elm = Elm.parentnode;
        }
        return true;
    }
});

For this piece of code to execute, you must add validate-must to the field you want to verify.

<style type= "Text/css" >
    #advice-required-entry-consent_year{Position:absolute;}
</style>
