hi, i want to show some extra fields in case of datebirth value tells the user is underaged.
i already have the checkBirth function, but how can i define onChange javascript action on that field?

Hi alfredopacino,

Give the checkbox an ID like datebirth then add this to a Load JS action in your form.

window.addEvent('domready', function() {
  $('datebirth').addEvent('blur', checkBirth);
});

You could also use the onKeyup event but then your checkBirth function would need to check to see if the date was complete.

You can also set up a datepicker that will only accept dates more than, say, 16 years in the past - but this can give you other validation problems.

here is my Custom code action who doesnt work
the onchange action seems do nothing

<?php
$giorno_adesso = date('d');
$mese_adesso = date('m');
$anno_adesso = date('Y');
?>
<script language="javascript">
window.addEvent('domready', function() {
  $('datebirth').addEvent('change', function() {
	var date=document.getElementById("datebirth").value;
alert("data: "+date);
   var anno=parseInt(date.substring(0,4),10);
var mese=parseInt(date.substring(5,7),10);
var giorno=parseInt(date.substring(8),10);
alert ("giorno "+giorno+" mese "+mese+" anno "+anno)

if((<?php echo $anno_adesso ?> - anno) > 18 ) { alert ("sei maggiorenne");    }

   else if ((<?php echo $anno_adesso ?> - anno) < 18 ) { alert ("sei minorenne");    }

   else if(((<?php echo $anno_adesso ?> - anno) == 18) && (<?php echo $mese_adesso ?> >= mese) && (<?php echo $giorno_adesso ?> >= giorno))
            { alert ("sei maggiorenne");  }

           else { alert ("sei ancora minorenne");    }
	
	

  });
});

</script>

this is the entire form field

<label for="datebirth">Data di nascita</label><input style="display: none;" id="datebirth" maxlength="150" size="16" class="validate['required'] cf_date_picker" title="" name="datebirth" value="2007-05-25" type="text"><input id="datebirth_clone_id" style="display: inline-block;" maxlength="150" size="16" class="validate['required'] cf_date_picker" title="" value="2007-05-25" type="text">
<div class="clear"></div><div id="error-message-datebirth"></div>

should i add #datebirth_clone_id somewhere to js function?

Hi alfredopacino,

Please post a link to the form so I can take a quick look.

Bob

im still in local..
the field has id #datebirth but chronoform print #datebirth_clone_id for the actually visible input field, i tryed to replace datebirth for datebirth_clone_id in the function but still doesnt work.

Hi alfredacino,

That used to happen with the old Monkeyphysics datepicker. Please try using the MooTools datepicker - you can switch over on the form General tab.

Bob

:D i solved thanks.

a little question yet: the datepicker tells the birthdate so it can't be tomorrow 🙂 , there's any change to disable future dates?
