Answer 1

From what I can tell, this may be a limitation of the validate plugin. There are several options for triggering the validation (which is what you want to do) given at http://docs.jquery.com/Plugins/Validation/validate#toptions but I don't see a way to trigger validation on one element when another element changes.

Your best bet is to place your validation code in something like this:

$('select#siteid').onChange(function(){
        $('form.validatedform').validate({ 
                 rules:{
                       email: {
                              required: true,
                              email: true,
                              remote: 'emailcheck2.asp?siteid=' + $('#siteid').val()
                       }
                  }
         });
  });

The plugin caches the value for performance reasons. As a workaround for now you could try to invalidate the cache manually whenever the dependent value changes:

$("#site").change(function() {
  $("#email").removeData("previousValue");
});

Hi if you are using this jquery valdation plugin, http://docs.jquery.com/Plugins/Validation/validate

If you want to send additional parameters(e.g. siteid) for remote validation, you can do something like this:

var enquiryform = {
        rules: {
            email: {
                required: true,
                email: true,
                remote: {
                    url: "emailcheck2.asp", //this should be the full path url including base url
                    data: {
                        siteid: function() {
                            return $('#siteid').val();
                        }
                    }
                }
            }
        }
    };
