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
