Javascript onclick只能运行一次

Question

所以我做了这个,

var Coin = document.getElementById("coin");

Coin.onclick = function() {
    Coin.style.webkitTransform = "rotateY(1800deg)";
    Coin.style.MozTransform = "rotateY(1800deg)";
    Coin.style.msTransform = "rotateY(1800deg)";
    Coin.style.OTransform = "rotateY(1800deg)";
    Coin.style.transform = "rotateY(1800deg)";
}

在它里面,一枚硬币旋转.但是,它只发射一次.我第一次点击它.它之后不再发射.救命!

Answer 1

每次点击硬币时它都保持在1800度,要在每次点击时旋转它,你需要增加它的度数,如下例所示:

var Coin = document.getElementById("coin");
var degrees = 0;
Coin.onclick = function() {
  degrees += 1800;
  console.log(degrees)
  Coin.style.webkitTransform = "rotateY(" + degrees + "deg)";
  Coin.style.MozTransform = "rotateY(" + degrees + "deg)";
  Coin.style.msTransform = "rotateY(" + degrees + "deg)";
  Coin.style.OTransform = "rotateY(" + degrees + "deg)";
  Coin.style.transform = "rotateY(" + degrees + "deg)";
}

body {
  -webkit-transform: perspective(500px);
  -webkit-transform-style: preserve-3d;
}

.coin {
  background-image: url("http://coins.thefuntimesguide.com/images/blogs/presidential-dollar-coin-reverse-statue-of-liberty-public-domain.png");
  background-size: 100% 100%;
  border-radius: 100%;
  height: 100px;
  margin: 50px auto;
  position: relative;
  width: 100px;
  -webkit-transition: 2s linear;
  -webkit-transform-style: preserve-3d;
}

<div class="coin" id="coin"></div>
