Здравствуйте, подскажите пожалуйста, как прикрутить код js валидации чтобы работал
вот ссылка на bootstrap
bootstrap-4.ru/docs/4.2.1/components/forms/#validation// ВОТ ЭТОТ КОД НИЖЕ НУЖНО ВСТАВИТЬ В REACT
<script>
// Example starter JavaScript for disabling form submissions if there are invalid fields
(function() {
'use strict';
window.addEventListener('load', function() {
// Fetch all the forms we want to apply custom Bootstrap validation styles to
var forms = document.getElementsByClassName('needs-validation');
// Loop over them and prevent submission
var validation = Array.prototype.filter.call(forms, function(form) {
form.addEventListener('submit', function(event) {
if (form.checkValidity() === false) {
event.preventDefault();
event.stopPropagation();
}
form.classList.add('was-validated');
}, false);
});
}, false);
})();
</script>
Это класс React
