如何暂停Spinkit动画？

我正在使用来自Spinkit的加载指示器，特别是圆圈指示器，但我没有想到如何暂停动画，因此圆圈仍然可以在屏幕上不旋转。

CSS是this。根据{{​​3}}的回答，我尝试使用jQuery点击此类：

.paused{
  -webkit-animation-play-state:paused;
  -moz-animation-play-state:paused;
  -o-animation-play-state:paused;
  animation-play-state:paused;
}


$(document).ready(() => {
  $('.sk-circle').click(function() {
    $(this).toggleClass('paused')
  })
})
.sk-circle {
  margin: 40px auto;
  width: 40px;
  height: 40px;
  position: relative;
}
.sk-circle .sk-child {
  width: 100%;
  height: 100%;
  position: absolute;
  left: 0;
  top: 0;
}
.sk-circle .sk-child:before {
  content: '';
  display: block;
  margin: 0 auto;
  width: 15%;
  height: 15%;
  background-color: #333;
  border-radius: 100%;
  -webkit-animation: sk-circleBounceDelay 1.2s infinite ease-in-out both;
  animation: sk-circleBounceDelay 1.2s infinite ease-in-out both;

  <div class="sk-circle12 sk-child"></div>
</div>

但是动画没有暂停，圆圈继续旋转。你能帮帮我吗？

答案 0 :(得分：1)

您的代码无法正常工作的原因是因为您在点击时将已暂停类添加到.sk-circle，但动画实际上存在于 .sk-child 元素＆＃39>伪。

因此，修改jQuery代码，以便在.sk-child元素上添加该类，然后在CSS中设置animation-play-state: paused下的.sk-circle .sk-child.paused:before。这会将暂停的播放状态设置为动画。 （选择器必须更具体，因为添加动画的选择器具有021的特异性。）

注意：我已删除了以下代码段中的浏览器前缀，并添加了无前缀库以保持较小。
