Запрет повторной анимации
Здравствуйте уважаемы форумчане. Подскажите пожалуйста как запретить повторную анимацию при многократном наведении мыши. Прилагаю пример:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
<link rel="stylesheet" href="css/normalize.css">
<style>
.wrapper{
max-width: 1278px;
margin: 40px auto;
line-height: 140%;
}
.clearfix:before, .clearfix:after{
content: " ";
display: table;
}
.clearfix:after{
clear: both;
}
.hover {
float: left;
}
.show {
float: left;
width: 400px;
background-color: #f6f6f6;
padding: 10px;
float: left;
margin-left: 40px;
display: none;
}
</style>
</head>
<body>
<div class="wrapper clearfix">
<div class="hover"><a class="hover__link" href="#">Lorem ipsum</a></div>
<div class="show"><p>Lorem ipsum dolor sit amet, consectetur adipisicing elit. Eum excepturi voluptatem expedita ipsa totam tenetur corporis at. Officia voluptates impedit sed, dicta laborum aliquid aut dolorem natus. A, veritatis alias.</p></div>
</div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.0.0-beta1/jquery.min.js"></script>
<script src="js/main.js"></script>
</body>
</html>
$(function() {
var flag = true;
var timer;
var show = function(elements, el) {
$(elements).on('mouseenter', function() {
clearTimeout(timer);
$(el).fadeIn(300);
})
$(elements).on('mouseleave', function() {
timer = setTimeout(function() {
$(el).fadeOut(300);
},100)
});
}
show(".hover, .show", ".show");
});

Спасибо! А как сделать тоже самое, но на js (без библиотек)?
|
s24344,
написать свои mouseenter и mouseleave fadeIn fadeOut https://learn.javascript.ru/mousemov...ter-mouseleave https://learn.javascript.ru/js-animation этих двух ссылок достаточно, чтобы это осуществить ... хотя можно придумать вариант без js на одном css. |
Спасибо.
|
Последний вопрос: как реализовать .stop(true, true) ?

fadeIn fadeOut на чистом js
