Question

Is it possible to write a dependency callback for the minValue rule, such as you can with the required text?

I have 2 required fields -> Price Paid and Price Seen (for a rebate form). I tried to write something like this:

     minValue: function(element) {
          $("#PP_PriceSeen").val();
     }

if I try to set an alert or something, I do get the correct value, but it isnt being passed into the rule. Is this only allowed for the ‘required’ option?

Thanks

It would be easy enough to accomplish this with a custom validator rule:

$.validator.addMethod("minDependency", function (value, element, params) {
    return this.optional(element) || ((parseInt(value, 10) || 0) >= (parseInt($(params).val(), 10) || 0));
}, "Please enter at least the minimum value");

$("#test").validate({
    rules: {
        fieldName: {
            minDependency: "#min"
        }
    }
});

This defines a new rule minDependency that accepts a selector as a parameter. The selector’s value is compared against the element under validation.
