Javascript: Change other fields based on selection

[JtheBAB]

Dear all

I have a simple form with the fields:

phone_type_idphone_type (Select)
country_idcount (Select)
phone_area_co (text)
phonenumber (text)

When the user select a value in phone_type_idphone_type (select) the javascript should change the values of the other three fields.

So i tried with the help of ChatGPT4 to get it running. That was the output based on the facts that we gathered... but non of the scripts suggestions worked

function dadabik_phone(field) {
  if (field.value == '2') {
    document.getElementById('country_idcountry').getElementsByTagName('input')[0].value = '1';
    document.getElementById('phone_area_code').getElementsByTagName('input')[0].value = '22';
    document.getElementById('phonenumber').getElementsByTagName('input')[0].value = '123';
  }
}

How can i change the other fields on this form based on the value that is selected in phone_type_idphone_type?

Thanks

Hello,
instead of adding custom code, have you tried to use cascade fields? They may work in your case. Check the inline help in form configrator for the cascade parent field parameter.

Best,

Hi

Cascade fields are interesting but unfortunately not in this case.

phone_type_idphone_type defines if the phone is internal or external. And when it is internal it should already prefill country_idcount and phone_area_code. Additional it should add in the field phonenumber some required numbers. So that the users can just type the last 4 digits of the number.

Thanks
