validate certain fields based upon dropdown selection

Posted on 2013-12-04
Last Modified: 2013-12-05
I'm currently using jQuery to validate a simple user profile form and was wondering how I could validate certain fields based upon a dropdown selection.

basically i have a country dropdown with 2 options: US and Canada. If US is selected, the states dropdown appears and the provinces is hidden. if canada is chosen, then the provinces dropdown is shown and the states dropdown is hidden. I want to be able to validate whichever field is shown.

I tried the following code and applied a class called "info" to each dropdown (selStates and selProvinces) but it doesn't work. any ideas greatly appreciated

                submitHandler: function (form) {
                ignore: "text :hidden, .select2-input, #s2id_autogen1, #s2id_autogen2",
                rules: {
                    txtFirstName: { required:true, maxlength:50 },
                    txtLastName: { required:true, maxlength:50 },
                    txtEmail: {
                        required: true,
                        email: true,
                        remote: {
                            url: "editProfile.asp",
                            data: { emailExists: "y" }
                    txtCity: { required:true, maxlength:50 },
                 //   selState: "required",
                    txtDOB: "required",
                    txtMotto: {
                        maxlength: 50
                    txtAboutMe: {
                        maxlength: 200
                messages: {
                    txtFirstName: { required: "Please enter your first name", maxlength: "Please limit your first name to 50 charactors or less." },
                    txtLastName: { required: "Please enter your last name", maxlength: "Please limit your last name to 50 charactors or less." },
                    txtCity: "Please enter your city",
                    txtEmail: {
                        required: "Please enter a valid email address",
                        remote: "This email already exists, please try another email"
                    txtDOB: "Please enter in your Date Of Birth",
                    txtMotto: "Please keep your motto to 50 charactors or less",
                    txtAboutMe: "Please keep your About Me description to 200 charactors or less"

            $('.info').each(function() {
                $(this).rules('add', {
                    required: true,
                    messages: {  required:  "You must select a state or province"  }
