change visibility of a div based on radio button

Question

I already checked

• CSS and hiding/showing divs when radio button checked
• and If Radio button checked show div

My problem is a little bit different I use WordPress and in the input generated by WordPress there is no id and in fact, the front generated is like this JSFiddle, I can not change the HTML code.

Is there any solution to only show id="DateDD" if users clicked on Choose delivery date

JSFiddle

Update:

Code added.

<h5 class="text-brown pt-4">Please select delivery date:</h5>
<div class="form-check">
  <div data-priority="" class="form-row my-field-class form-row-wide pl-3" id="send_date_field">
    <fieldset>
      <legend></legend><label><input type="radio" name="send_date" value="Send as soon as possible"> Send as soon as possible</label><label><input type="radio" name="send_date" value="Choose delivery date"> Choose delivery date</label>
    </fieldset>
  </div>

Answer 1

From looking at your JSFiddle, you would need to target the name attribute on those radio selects. If the value equals "Choose delivery date" show the delivery date div.

const deliveryDate = document.getElementById('DateDD');
const sendOptions = document.querySelectorAll('[name="send_date"]');

// Hide initially
deliveryDate.style.display = 'none';

// Add event listeners to both radios,
// Show deliveryDate based on value of selected radio
sendOptions.forEach((send) => {
  send.addEventListener('click', (event) => {
    if (event.target.value === 'Choose delivery date') {
      deliveryDate.style.display = 'block';
    } else {
      deliveryDate.style.display = 'none';
    }
  });
});
