Force at least one field to be required

Question

I have 4 Checkbox in my form HTML, I am working on validations only with Jquery.Validate, there is a way that I define that at least 1 of these checBox is triggered?

Some property of validate? Or just creating a function in race?

I found something on here Apparently the solution seems practical and feasible, but in my case I don’t have a name for the checkedbox group

My code is like this:

<td colspan="2">Você conversou com quem?
   <input type="checkbox" name="Diretor" id="Diretor" />Diretor
   <input type="checkbox" name="Vice" id="Vice" />Vice-Diretor
   <input type="checkbox" name="Coordenador" id="Coordenador" />Coordenador
   <input type="checkbox" name="Nenhum" id="Nenhum"  />Não conversei com ninguem
</td>

I think what you need is the method require_from_group validates if an item in a group is completed.

On the plugin page (link above) you have this example:

$( "#myform" ).validate({
  rules: {
    mobile_phone: {
      require_from_group: [1, ".phone-group"]
    },
    home_phone: {
      require_from_group: [1, ".phone-group"]
    },
    work_phone: {
      require_from_group: [1, ".phone-group"]
    }
  }
});

In your case the code could be like this: http://jsfiddle.net/n1581gkx/1/

and then you need to have these files loaded:

<script src="http://jqueryvalidation.org/files/dist/jquery.validate.min.js"></script>
<script src="http://jqueryvalidation.org/files/dist/additional-methods.min.js"></script>
