Change hidden input value

Question

I want change hidden input value from other input value.

This is code:

 $(document).ready(function() {
$(\'input:text[name="'.$data['name'].'"]\').keyup(function() {
 $(\'input:hidden[id="'.$data['name'].'"]\').val( "'.$data['id'].'," + $(this).val() );
});
 });

This code work but i don't know how to change from keyup to always set value even if he does not edit the field and the field contains data from the database If I don't edit the field, it won't load anything into the hidden field

I entered various functions in various ways and nothing

Can you clarify what you mean by to always set value even if he does not edit the field; why would it need to be updated if the original is not edited? What does your html look like? You should be able to initialize the value of the hidden input the same way you do the text input. — mykaf

because i must have value in input. I delete all data from database when click send and add new edited. This is only one way for my project for edit data by admin. — VaderStudents

try to use following code , it changes the value of input:text when input:hidden value changes.

$(document).ready(function() {
        // this part handles when input:text field changes value 
            $('input:text[name="' + $data['name'] + '"]').on('input', function() {
                $('input:hidden[id="' + $data['name'] + '"]').val($data['id'] + ',' + $(this).val());
              });

// this part handles when loading page , set value of hidden input by value of input:text value 
    let $textInput = $('input:text[name="' + $data['name'] + '"]');
        let $hiddenInput = $('input:hidden[id="' + $data['name'] + '"]');
   let $textval = $textInput.val();
      $hiddenInput.val($textval);
            });
