If you want to see if there’s a valid element in a querystring and then take an action you can use JavaScript to parse the website URL:
// 1. Get the query string from the current URL
const urlParams = new URLSearchParams(window.location.search);
// 2. Check if the 'AddNew' parameter exists and equals '1'
if (urlParams.get('AddNew') === '1') {
// 3. Find your form field by its ID and focus on it
const targetField = document.getElementById('your-field-id');
if (targetField) {
targetField.focus();
}
}
