Answer 1

hoho, i know why in the validate.js the email check is not have parameters the old code

        email: function(value, element) {
        return this.optional(element) || /^(((....)))\.?$/i.test(value);
    },

the new code

        email: function(value, element, param) {
        if (!param) {
            return true;
        }
        return this.optional(element) || /^(((....)))\.?$/i.test(value);
    },

when customer_info = 1 ,the eamil validate is not work. but i have other question,when i wirte eamil:false, the email validate is not work,so what diffrent for

email:function(){return false}

to

email:false
