Calender

how to make a wound on the calendar date?
come fare una ferita alla data del calendario?
​

What do you mean a "wound"?
​
And if you want to compare dates on the frontend, CF uses the moment.js libray.

Thanks for the reply
​
"wound"error of the translation sorry
​
I created a forum where the user enters a date from the calendar
if data is included between 12/22/2019 and 12/28/2019 a Var ts has a value of 10 else 5
​
I hope I was able to explain myself
​

jQuery(document).on('change', 'input[name="calendar_name"]', function() {
   let date = jQuery(this).val();
   if(moment(date).isBetween('2019-12-22', '2019-12-28')) {
      // Do whatever it is you're doing here
   }
}

     jQuery(document).on('change', 'input[name="calendar22"]', function() {
   let date = jQuery(this).val();
   if(moment(date).isBetween('22-12-2019', '28-12-2019')) {

var ts = 2.50;

}else{
var ts = 5.00;
}

});    


op("#tipologia_biglietto").change(function (tipo) {          
               if (op("#tipologia_biglietto").val () == "Andata & ritorno") {                

op('#biglietto').val ('Andata & ritorno');
op('#tassa_di_sbarco').val (ts);
 
}
else if (op("#tipologia_biglietto").val () == "Solo Andata"){
op('#biglietto').val ('Solo Andata');
op('#tassa_di_sbarco').val (ts);
     

}
else 
{
op('#biglietto').val ('Solo Ritorno');
op('#tassa_di_sbarco').val ('0');

}
  
            }
);

does not work

Of course not those values are only available there you should do all your functions inside it, and it should also be inside a JavaScript block with the Dom ready option ticked
