Checkboxes validation

Hello,

The page is: http://adplus.ee/arendus/excellent2/kasutajatugi

I have need to check, that at least one of the checkboxes is cheked.
I tried for start information from this forum topic: http://www.chronoengine.com/forums/posts/f26/t66192/js-checkbox-validation-help.html?hilit=checkbox+validation, but it did not work.

I make some changes to the script:

window.addEvent('domready', function() {
  $('checkbox_group12').addClass("validate['%countCheck']");
});

var countCheckMin = 1;
function countCheck(el){
  var group = el.getSiblings(['input']);
  group.include(el);
  var count = 0;
  group.each(function(item) {
    if ( item.checked ) {
      count++;
    }
  });
   if ( count < countCheckMin ) {
    el.errors.push("Palun vali vähemalt "+countCheckMin+" teema");
    return false;
  } else {
    return true;
  }
}

Every checkbox have its own id and the script is adding class only for the first checkbox. Added class looks like

class="A validate['%countCheck']"

..

My javascript knowleage is very limited, but I need that functionality very much.

Hi jaak,

I suggest that you give all of the checkboxes the same array name e.g. kysymys[] and make the group required.

Hello,

Can you be littele more specific.
How should I change my code.

Jaak

Hi Jaak,

1. Give all the checkboxes the same name kysymys[]

2. Add class='validate['group:1'] to each checkbox.

Bob

PS I noticed that at lease one of your checkboxes had a name with a special character in it - an ã perhaps - those are not permitted in HTML names, only a-z
