按钮单击时连续重复CSS转换/动画持续时间？

Question

我有一个简单的双面“卡”，前面有一个按钮（标有“下一个”），后面有另一个按钮（标有“后面”）。每个按钮触发jquery以垂直方式旋转“卡片”，使用转换持续时间：2秒，这样可以看到卡片正在“翻转”，而不是只是瞬间翻转。我的问题是，在我按下每个按钮一次后，我无法再次触发“transition-duration / animation-duration”。我可以尝试将它放在我的Jquery函数中，但我不明白为什么我的CSS动画持续时间没有在每次按钮点击时触发（它只适用于每个按钮1次点击，“卡”相应地翻转到后面，然后一旦我按下按钮一次，再次前面）。我从表单中删除了大部分信息，因此告诉我要求的内容要容易一些。任何帮助，将不胜感激。

  $("input[name='next']").on("click", function() {

  $("input[name='back']").on("click", function() {
    console.log("The BACK Button Worked!");
    $(".formFlipAgain").css("transform", "rotateY(180deg)");
  })
});

Answer 1

我认为这是你想要实现的结果，你不需要额外的类'.formFlipAgain'。你用类'.form'180度旋转div，它仍然处于那种状态，这导致瞬间翻转，你只需要将其旋转回来。

$(document).ready(function() {
  $("input[name='next']").on("click", function() {
    console.log("The NEXT Button Worked!");
    $(".form").css("transform", "rotateY(180deg)");
  })
  $("input[name='back']").on("click", function() {
    console.log("The BACK Button Worked!");
    $(".form").css("transform", "rotateY(0deg)");
  })
});

function showBack() {
  setTimeout(function() {
    document.getElementById("backSide").style.display = "block";
  }, 600);
  setTimeout(function() {
    document.getElementById("frontSide").style.display = "none";
  }, 600);
};

function showFront() {
  setTimeout(function() {
    document.getElementById("frontSide").style.display = "block";
  }, 600);
  setTimeout(function() {
    document.getElementById("backSide").style.display = "none";
  }, 600);
};

.form {
  transform-style: preserve-3d;
  -webkit-transition-duration: 2s;
  -moz-transition-duration: 2s;
  -o-transition-duration: 2s;
  transition-duration: 2s;
}
.formFlipAgain {
  transform-style: preserve-3d;
  -webkit-transition-duration: 2s;
  -moz-transition-duration: 2s;
  -o-transition-duration: 2s;
