只需单击一次即可将CSS反弹动画添加到div

问题描述 投票：4回答：2

我有一个CSS地图引脚，它有一些CSS3动画，这里是：'

https://jsfiddle.net/xg7xfzeq/

body {
  background: #e6e6e6;
}

.pin {
  width: 30px;
  height: 30px;
  border-radius: 50% 50% 50% 0;
  background: #00cae9;
  position: absolute;
  transform: rotate(-45deg);
  left: 50%;
  top: 50%;
  margin: -20px 0 0 -20px;
}
.pin:after {
  content: "";
  width: 14px;
  height: 14px;
  margin: 8px 0 0 8px;
  background: #e6e6e6;
  position: absolute;
  border-radius: 50%;
}

.bounce {
  animation-name: bounce;
  animation-fill-mode: both;
  animation-duration: 1s;
}

.pulse {
  background: #d6d4d4;
  border-radius: 50%;
  height: 14px;
  width: 14px;
  position: absolute;
  left: 50%;
  top: 50%;
  margin: 11px 0px 0px -12px;
  transform: rotateX(55deg);
  z-index: -2;
}
.pulse:after {
  content: "";
  border-radius: 50%;
  height: 40px;
  width: 40px;
  position: absolute;
  margin: -13px 0 0 -13px;
  animation: pulsate 1s ease-out;
  animation-iteration-count: infinite;
  opacity: 0;
  box-shadow: 0 0 1px 2px #00cae9;
  animation-delay: 1.1s;
}

@keyframes pulsate {
  0% {
    transform: scale(0.1, 0.1);
    opacity: 0;
  }

  50% {
    opacity: 1;
  }

  100% {
    transform: scale(1.2, 1.2);
    opacity: 0;
  }
}

@keyframes bounce {
  0% {
    opacity: 0;
    transform: translateY(-2000px) rotate(-45deg);
  }

  60% {
    opacity: 1;
    transform: translateY(30px) rotate(-45deg);
  }

  80% {
    transform: translateY(-10px) rotate(-45deg);
  }

  100% {
    transform: translateY(0) rotate(-45deg);
  }
}
.myBounceDiv { 
        -moz-animation:bounce .40s linear;  
        -webkit-animation:bounce .40s linear; 
} 

@-moz-keyframes bounce {


 0%{ -moz-transform:scale(0); opacity:0;}
        50%{ -moz-transform:scale(1.3); opacity:0.4; }
        75%{ -moz-transform:scale(0.9); opacity:0.7;}
        100%{ -moz-transform:scale(1); opacity:1;}
}

@-webkit-keyframes bounce {
        0%{ -webkit-transform:scale(0); opacity:0;}
        50%{ -webkit-transform:scale(1.3); opacity:0.4;}
        75%{ -webkit-transform:scale(0.9); opacity:0.7;}
        100%{ -webkit-transform:scale(1); opacity:1;}
}

和它的HTML

<div class='myBounceDiv'>
<div class='pin bounce'></div>
<div class='pulse'></div>
</div>

好吧，我想在点击时添加弹跳css3动画，我已经找到了一些解决方案，例如当我们使用javascript点击它的div时改变CSS样式。虽然它是可能的，但当我改变它的CSS类时，它将开始永远反弹。怎么能让它只有一次动画？一种方法可能是触发一个计时器，并在1000毫秒后将其css类更改为其第一个类，但还有另一个问题，我的div类有另一个动画（当它首次出现在页面中时，它从上到下掉落）所以如果我将其css类更改为弹跳动画，并再次将其更改为原始的外观动画trigers，这不是我需要的。有没有办法用纯javascript和CSS实现我需要的东西？事实上，我需要制作像这样的http://dynamicsjs.com/examples/pin.html，但它的动画出现在点击使用CSS。

您可以改为（在点击时）并删除（在1s之后）类到pin或myBounceDiv，而不是将CSS类更改为弹跳动画并返回原始动画。需要注意的是，一旦动画完成，您还需要删除bounce类。

它看起来像这样：

const pinEl = document.querySelector('.pin');

setTimeout(() => pinEl.classList.remove('bounce'), 1000);
function removeMiniBounce() {
    pinEl.classList.remove("miniBounce");
  }
pinEl.onclick = () => {
  pinEl.classList.add("miniBounce");
  setTimeout(removeMiniBounce, 1000);
}

你的CSS将是：

@keyframes miniBounce {
    0%{ -webkit-transform:translateY(0px) rotate(-45deg);}
    30%{ -webkit-transform:translateY(-20px) rotate(-45deg);}
    60%{ -webkit-transform:translateY(0px) rotate(-45deg);}
    70%{ -webkit-transform:translateY(-5px) rotate(-45deg);}
    100%{ -webkit-transform:translateY(0) rotate(-45deg);}
}

.miniBounce {
  animation: miniBounce 0.4s ease-in-out; 
}

据我所知，你的意思是：

  • 在第一个版本中，脉冲效果和弹跳效果仅运行一次
  • 在第二个版本中，脉冲效果始终像当前版本一样运行，但跳出效果仅运行一次

第一版
