Я работал над созданием этой страницы TOS, но столкнулся с проблемой анимации появления и исчезновения.
Я заставил div исчезать при нажатии кнопки, но не знаю, как сделать так, чтобы он исчезал при повторном нажатии кнопки. Любые советы будут полезны
https://jsfiddle.net/MakkerHeineken/khs8b43f/1/
function unhideTOS() {
document.getElementById("text").style.display = "";
}
function unlockBTN() {
document.getElementById("text").style.display = "";
}
function scrollToAccept() {
const terms = document.querySelector('.terms-and-conditions');
const button = document.querySelector('.accept');
// const watch = document.querySelector('.watch');
if (!terms) {
return; // quit function because there is no terms
}
// fires on page load because can't find element
function obCallback(payload) {
// console.info(payload[0].isIntersecting); // whether element is in view or not
// console.info(payload[0].intersectionRatio); // how much of the element is showing
if (payload[0].intersectionRatio === 1) {
button.disabled = false;
// stop observing the last element
ob.unobserve(terms.lastElementChild);
}
}
// takes in callback parameter
// will be called every time it needs to check if something is currently on the page
// watcher (needs to be told what to watch
const ob = new IntersectionObserver(obCallback, {
root: terms,
threshold: 1,
});
// call observe method on what we want to watch
// ob.observe(watch);
ob.observe(terms.lastElementChild);
}
scrollToAccept();
$('.yes').on('click', function(e) {
e.preventDefault();
$('.TOSHIDE').toggleClass('active');
//$(this).parents('ul').next().toggleClass('active');

См. Как спросить. Вы включили сюда гораздо больше кода, чем необходимо для демонстрации вашей проблемы.
сделал код для переключателя, который вам, вероятно, не нужен. Основная часть — это анимация затухания:
//toggle var
var fade_state = true;
//on btn click
function fade() {
//get the button and div
let div = document.getElementById("div");
let btn = document.getElementById("fade");
//if faded in or out
if (fade_state == true) {
//trigers animation
div.style.animation = "fade-out 2s forwards";
//sets the text
btn.innerHTML = "fade-in";
//sets fade_state
fade_state = false;
} else if (fade_state == false) {
//trigers animation
div.style.animation = "fade-in 2s forwards";
//sets the text
btn.innerHTML = "fade-out";
//sets fade_state
fade_state = true;
}
}
div {
width: 30vw;
height: 30vh;
background-color: blue;
opacity: 100%;

@keyframes fade-out {

Когда вы используете jQuery, вы можете использовать метод исчезатьToggle. Для вашего кода просто замените $('.TOSHIDE').toggleClass('active');
в вашем JavaScript на $('.TOSHIDE').fadeToggle();
и немного поиграйте с параметрами продолжительности.
Более простой подход с использованием анимации jQuery, без анимации CSS.
function scrollToAccept() {
const terms = document.querySelector('.terms-and-conditions');
const button = document.querySelector('.accept');
// const watch = document.querySelector('.watch');
if (!terms) {

}
// fires on page load because can't find element
function obCallback(payload) {

Есть ли конкретная причина, по которой мы не просто переключаем класс css и используем переходы? Вы можете просто переключить класс в обертке div и настроить все, что вам нравится. Я не уверен, что понимаю необходимость всех сценариев.
