使用 CSS 动画对 div 进行动画处理，两者之间略有延迟

Question

我想做的基本上是一个通知栏，我想用CSS动画显示和隐藏它。问题是我无法在两个动画的发生之间产生大量的延迟。

.HTML

<div id="notification" class="alert" role="alert"></div>

.JS

$('#notification').html('This place is already occupied!').addClass('alert-warning animated bounceInDown').show().delay(5000).addClass('bounceOutUp');

.CSS

#notification {
    position: fixed;
    top: 5px;
    border-radius: 0;
    width: 100%;
    display: none;
    z-index: 1200 !important;
}
.animated {
    -webkit-animation-duration: 1s;
    animation-duration: 1s;
    -webkit-animation-fill-mode: both;
    animation-fill-mode: both;
}
@-webkit-keyframes bounceInDown {

Answer 1

您可以添加一个animationend事件侦听器，该侦听器带有一个setTimeout()，用于在动画运行后添加下一个动画。

var $notification = $('#notification'),
    delay = 5000;
$notification.html('This place is already occupied!').addClass('alert-warning animated bounceInDown').show().one('animationend',function() {  
  var timeout = setTimeout(function() {
    $notification.addClass('bounceOutUp');
  },delay)
});

#notification {
  position: fixed;
  top: 5px;
  border-radius: 0;
  width: 100%;
  display: none;
  z-index: 1200 !important;
}
.animated {
  -webkit-animation-duration: 1s;
  animation-duration: 1s;
  -webkit-animation-fill-mode: both;
  animation-fill-mode: both;
}
@-webkit-keyframes bounceInDown {
  from,
  60%,
  75%,
  90%,
  to {
    -webkit-animation-timing-function: cubic-bezier(0.215, 0.610, 0.355, 1.000);
    animation-timing-function: cubic-bezier(0.215, 0.610, 0.355, 1.000);
  }
  0% {
    opacity: 0;
    -webkit-transform: translate3d(0, -3000px, 0);
    transform: translate3d(0, -3000px, 0);

}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="notification" class="alert" role="alert"></div>

您也可以使用相同的技术，只需将.bounceOutUp类的animation-delay更改为 5s，而不是使用计时器。

var $notification = $('#notification');
$notification.html('This place is already occupied!').addClass('alert-warning animated bounceInDown').show().one('animationend',function() {
  $(this).addClass('bounceOutUp');
});

#notification {
  position: fixed;
  top: 5px;
  border-radius: 0;
  width: 100%;
  display: none;
  z-index: 1200 !important;
}
.animated {
  -webkit-animation-duration: 1s;
  animation-duration: 1s;
  -webkit-animation-fill-mode: both;
  animation-fill-mode: both;
}
@-webkit-keyframes bounceInDown {

  90%,
  to {
    -webkit-animation-timing-function: cubic-bezier(0.215, 0.610, 0.355, 1.000);
    animation-timing-function: cubic-bezier(0.215, 0.610, 0.355, 1.000);

Answer 2

不知道我是否正确理解你，但你可以用 css 做延迟：

div {
    -webkit-animation-delay: 2s; /* Safari 4.0 - 8.0 */
    animation-delay: 2s;
}
