        }
}

Question: How can I set above mentioned regexp to currency field with jquery ?

Answer 1

You could define a custom rule:

$.validator.addMethod('currency', function(value, element, regexp) {
    var re = /^\d{1,9}(\.\d{1,2})?$/;
    return this.optional(element) || re.test(value);
}, '');

and then:

$('#myForm').validate({
    ignore:[],
    rules: {
        currency: {
            currency: true
        }
        .....
    }
}
