[jQuery] Re: using depends method with Validate() plugin

[luke adamis]

Thanks!
I found the page as well:
http://docs.jquery.com/Plugins/Validation/Methods/required#dependency- 
expression

I wonder how I could miss this page.

OK

this works:

                       current_password: {
                                       minlength: 6,
                                       required: {
                                               depends:
"#new_password:filled"
                                         }
                                       },


I still need to figure out how to get a value recognized:

                       zip: {
                                       required: {
                                               depends:  
"#countrycode:'1'"
                                         }
                                        },

Hi,

I am using the Validate() plugin for various forms and I run into
this issue with the depends method on various places.

So far I found only two references to dealing with depends:

http://docs.jquery.com/Plugins/Validation/validate

$(".selector").validate({
   rules: {
     contact: {
       required: true,
       email: {
         depends: function(element) {
           return $("#contactform_email:checked")
         }
       }
     }
   }
})

http://dev.jquery.com/ticket/2456

billingAddress: {
  required:true,
  minlength:5
  equalTo: {
    param: "#shippingaddress",
    depends: "#compare:checked"
  }
}

first of all non of these work for me so there must be something
going on with them. but my real problem is that I want validation
depending on fields other then checkboxes.

1. I only want to require zip code if the selected country from a
drop down list is USA.

something like this:

zip: {
       required: {
               depends: "#countrycode:1"
               }
       },

where countrycode represents the country selector and 1 is the value
for USA

2. in a from for password change I only want to require current
password if new password is entered.
something like this:

current_password: {
       minlength: 6,
       required: {
               depends: "#new_password"
               }
       },

with this one I'd assume that if new_password is not empty then set
the rule.

I also found this page:
http://dev.distilldesign.com/log/2008/mar/16/extending-jquery-form-
validation-plugin/
http://lab.distilldesign.com/jquery-form-validation/extending/

this one works, though he uses checkboxes as well. here he basically
extends the validate() plugin:

$.validator.addMethod('dependsOn', function (value, el, params) {
                               return !$(params.el).is 
(params.being) ||
$(el).is(':filled');
                       }, 'This field is required.');

then he uses the new method in the rule:

emailDependent: {
       dependsOn: {
               el: '#emailMethod',
                       being: ':checked'
               },
       email: true
},


I am not a javascript wizard so this method writing is getting my
head dizzy. Can anyone tell me if there is a simple way of using
depends in rules for validate() plugin?

Thanks,
Luke
