仅在选中复选框时才需要复选框文本字段

Question

Is it possible to make the fields required only when I have the checkboxes checked? Below is what I attempted but I can't seem to get it to work.

So I want to be able to have the field 1 and two only required when the checkboxes are checked on either.

I've attempted the below Javascript code but I can't seem to get it to work properly.

let toggleInputRequired = ( checkbox, input ) => {
    checkbox.addEventListener( 'change', e => {
        if ( e.currentTarget.checked )
            input.setAttribute( 'required', 'required' );
        else
            input.removeAttribute( 'required' );
    } );

    checkbox.onchange();
}

toggleInputRequired( document.querySelector( 'input[name="rtk[checked][]"]' ), document.querySelector( 'input[name="rtk[5][field1]"]' ) );

 /* Resident Selection for Alert */ document.getElementById('resident').addEventListener('change', function() { if (this.value !== 'CA') { document.getElementById('stateWarning').style.display = 'block'; document.querySelector('#stateWarning b#stateName').textContent = this.options[this.selectedIndex].text; } else { document.getElementById('stateWarning').style.display = 'none'; } }); /* Right to Know */ const formWrapperPersonal = document.getElementById('form-wrapper-personal'); const formWrapperSpecific = document.getElementById('form-wrapper-specific'); document.getElementById('rtk1').addEventListener('change', (e) => { if (e.target.checked) { formWrapperPersonal.style.display = '' } else { formWrapperPersonal.style.display = 'none' } }); document.getElementById('rtk5').addEventListener('change', (e) => { if (e.target.checked) { formWrapperSpecific.style.display = '' } else { formWrapperSpecific.style.display = 'none' } }); /* Right to Delete */ const formWrapperCertainSelection = document.getElementById('form-wrapper-certain-selection'); const toggleCertainForm = () => { const formWrapper = document.getElementById('form-wrapper-certain'); const rtd3 = document.getElementById('rtd3'); formWrapper.style.display = rtd3.checked ? '' : 'none'; }; document.querySelectorAll('[name="rtd[checked]"]').forEach(r => r.addEventListener('change', toggleCertainForm) ); document.getElementById('rtd3Transaction').addEventListener('change', (e) => { if (e.target.checked || document.getElementById("rtd3Device").checked) { formWrapperCertainSelection.style.display = '' } else { formWrapperCertainSelection.style.display = 'none' } }); document.getElementById('rtd3Device').addEventListener('change', (e) => { if (e.target.checked || document.getElementById("rtd3Transaction").checked) { formWrapperCertainSelection.style.display = '' } else { formWrapperCertainSelection.style.display = 'none' } });

Answer 1

Your code is so congested so here is the demo that you want. Hope this helps you!

Just under document ready have change event on checkbox and check if the textbox have requird attribute . Just toggle it with the help of if else condition.

 $(document).ready(function() { $('.checkbox').change(function() { if ($('.inputBox').attr('required')) { $('.inputBox').removeAttr('required'); } else { $('.inputBox').attr('required','required'); } }); });

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script> <form> <p><input type="checkbox" class="checkbox" /> Check Me to make the Text Box a Required Field</p> <input type="text" class="inputBox" /> <input type="submit" value="Submit" /> </form>

You can check when the form is submitted. Let's say, the user selects first checkbox The categories of personal information get_company(); ?> has collected about you.

let checkbox1 = document.querySelector('.checkbox1:checked').value;
if(checkbox1){
  if(!document.getElementById('checkbox1InputFiedl1').value || 
  !document.getElementById('checkbox1InputFiedl2').value){
     alert("Error: fields not filled")
  }
}
