每次用户单击然后重新开始时，如何使用按钮启用 CSS 动画

Question

我只知道怎么做一次。但我希望当用户再次点击它时动画重新开始或重新开始。

我有 thiese:

function animation() {
  document.getElementById('ExampleButton').className = 'Animation';
}

.ExampleButtonCSS {
  position: fixed;
  bottom: 113px;
  background: rgba(0, 0, 0, 0);
  color: #cfcfcf;
  width: 100%;
  padding-left: 20px;
}

#ExampleButton {
  cursor: pointer;
  font-size: 15px;
  outline-color: #000;
  outline-style: auto;
  outline-width: 2px;
  padding: 5px;
  border: none;
  background: rgba(0, 0, 0, 0.25);
  color: #cfcfcf;
  opacity: 0;
}

.Animation {
  opacity: 0;
  animation: inactivity 5s ease normal;
}

@keyframes inactivity {
  from {
    opacity: 0;
  }
  10% {
    opacity: 1;
  }
  90% {
    opacity: 1;
  }
  to {
    opacity: 0;
  }
}

<div class="ExampleButtonCSS">
  <button id="ExampleButton" onclick="animation()">Fade in and Out</button>
</div>

所以，如果我点击它，我该怎么做，如果它已经在动画中，它会重新开始，或者如果它已经在任何时候结束，它会重新开始

Answer 1

我不太明白你想要什么。

但是您可以在动画完成后重置元素的 class。

function animation() {
  document.getElementById('ExampleButton').className = '';
  document.getElementById('ExampleButton').className = 'Animation';
  setTimeout(() => {
    document.getElementById('ExampleButton').className = '';
  }, 5000)
}

.ExampleButtonCSS {
  position: fixed;
  bottom: 113px;
  background: rgba(0, 0, 0, 0);
  color: #cfcfcf;
  width: 100%;
  padding-left: 20px;
}

#ExampleButton {
  cursor: pointer;
  font-size: 15px;
  outline-color: #000;
  outline-style: auto;
  outline-width: 2px;
  padding: 5px;
  border: none;
  background: rgba(0, 0, 0, 0.25);
  color: #cfcfcf;
}

.Animation {
  opacity: 0;
  animation: inactivity 5s ease normal;
}

@keyframes inactivity {
  from {
    opacity: 0;
  }
  10% {
    opacity: 1;
  }
  90% {
    opacity: 1;
  }
  to {
    opacity: 0;
  }
}

<div class="ExampleButtonCSS">
  <button id="ExampleButton" onclick="animation()">Fade in and Out</button>
</div>

Answer 2

你需要使用animationend event

<div class="ExampleButtonCSS">
  <button id="ExampleButton"> Fade in and Out </button>
</div>

const explmButton = document.getElementById('ExampleButton')

explmButton.onclick = () =>
  {
  explmButton.classList.add('Animation')
  }
explmButton.onanimationend = () =>
  {
  explmButton.classList.remove('Animation')
  }
