Question

我不确定如何描述它，所以请看这个例子：

＆＃13;

$('button').on('click', () => {
               $('.spinner').addClass('paused');
});

＆＃13;

.spinner {
}

.spinner > div {
  width: 25px;
  height: 25px;
  background-color: #9f9f9f;

  border-radius: 100%;
  display: inline-block;
  -webkit-animation: sk-bouncedelay 1.4s infinite ease-in-out both;
  animation: sk-bouncedelay 1.4s infinite ease-in-out both;
}

.spinner.paused > div {
  -webkit-animation: sk-pause 1.4s 1 ease-in-out both;
  animation: sk-pause 1.4s 1 ease-in-out both;
  // -webkit-animation-play-state: paused; /* Safari 4.0 - 8.0 */
  // animation-play-state: paused;
}
.spinner .bounce1 {
  -webkit-animation-delay: -0.32s;
  animation-delay: -0.32s;
}

.spinner .bounce2 {
  -webkit-animation-delay: -0.16s;
  animation-delay: -0.16s;
}

@-webkit-keyframes sk-bouncedelay {
  0%, 80%, 100% { -webkit-transform: scale(0.3) }
  40% { -webkit-transform: scale(1.0) }
}
@keyframes sk-pause {
  80%, 100% {transform: scale(0.3)}
}
@keyframes sk-bouncedelay {
  0%, 80%, 100% {
    -webkit-transform: scale(0.3);
    transform: scale(0.3);
  } 40% {
    -webkit-transform: scale(1.0);
    transform: scale(1.0);
  }
}

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div class="spinner">
              <div class="bounce1"></div>
              <div class="bounce2"></div>
              <div class="bounce3"></div>
 </div>

<button> Click </button>

你有三个弹跳的球。当您单击该按钮时，它会添加一个暂停的类，该类将动画显示为最小的可见球。但是当你点击时，它们都会从1.0比例变为0.3比例。我希望他们从之前的州过渡到0.3。

                animation-delay: -0.16s;

        }

        @keyframes sk-bouncedelay {
            0%, 80%, 100% {
                -webkit-transform: scale(0.3);
                transform: scale(0.3);

    <div class="spinner">
        <div id="div1" class="bounce1"></div>
        <div id="div2" class="bounce2"></div>
        <div id="div3" class="bounce3"></div>
    </div>

    <input type="button" id="a" value="Pause" />
    <script>
        $('#a').click(function ()
        {
            var computedStyle1 = window.getComputedStyle(document.getElementById("div1"));
            var computedStyle1 = window.getComputedStyle(document.getElementById("div1"));
        var computedStyle2 = window.getComputedStyle(document.getElementById("div2"));
        var computedStyle3 = window.getComputedStyle(document.getElementById("div3"));
        $('#div1').css('transform', computedStyle1.transform).css('-webkit-transform', computedStyle1.transform);
        $('#div2').css('transform', computedStyle2.transform).css('-webkit-transform', computedStyle2.transform);
        $('#div3').css('transform', computedStyle3.transform).css('-webkit-transform', computedStyle3.transform);
            $('.spinner').addClass('paused');
        });
    </script>
</body>

＆＃13;

我不知道什么是React，但我认为代码必须是这样的（而不是$('#a').click(function ()....块代码）：

$('#a').on('click', () => {
            var computedStyle1 = window.getComputedStyle(document.getElementById("div1"));
            var computedStyle2 = window.getComputedStyle(document.getElementById("div2"));
            var computedStyle3 = window.getComputedStyle(document.getElementById("div3"));
            $('#div1').css('transform', computedStyle1.transform).css('-webkit-transform', computedStyle1.transform);
            $('#div2').css('transform', computedStyle2.transform).css('-webkit-transform', computedStyle2.transform);
            $('#div3').css('transform', computedStyle3.transform).css('-webkit-transform', computedStyle3.transform);
            $('.spinner').addClass('paused');
        });
