/* egg & broke egg pair1 lite & broke lite pair2 pot & frys pair3 */
我想知道如何使图像配对或组合。因此,当您单击鸡蛋图像时,它会消失并出现破损的鸡蛋。然后这个图像也应该消失然后另外两个团队中的一个随机出现 lite 点击 lite break lite 随机出现和消失然后点击 pot 它变成 frys 然后 frys 消失并变成随机团队。

<body onLoad="setRandomImage()">
<img id="egg.png" src= "http//"onClick="setRandomImage();"/>
<img id="brokeEgg.png" src= "https://" style="display:none"/>
<img id="lite.png" src= "http://" style="display:none"/>
<img id="brokeLite.png" src= "http://" style="display:none"/>
<img id="pot.jpg" src= "https://style="display:none"/>
<img id="frys.jpg" src= "http://style="display:none"/>
<script type="text/javascript">
var myShapes= ["egg.png","brokeEgg.png","lite.png","brokeLite.png","pot.jpg","frys.jpg" ];
function setRandomImage() {
var imgElem = document.getElementById("egg.png")
imgElem.setAttribute('src',myShapes[Math.floor(Math.random()*6)]);
};
</script>

这是一个使用 HTML 的非常简化的 data-*
属性,但要考虑:
data-image-seq
属性的值必须是img
后跟一个数字。已更新
var imgs = document.querySelectorAll('.imgs-wrapper img'),
currentIMG = 1;
// attach click events on odd images only, egg, lite, pot, hi1, hello1
for (var i = 0; i < imgs.length; i += 2) {
addEvent(imgs[i], 'click');
}
function addEvent(element, event) {
element.addEventListener(event, function() {
var imgSeq = element.getAttribute('data-image-seq'),
nextImgSeq, nextImg, shownIMG;
imgSeq = parseInt(imgSeq.replace('img', ''), 10);
nextImgSeq = (imgSeq < imgs.length) ? (imgSeq + 1) : 1;
nextImg = 'img[data-image-seq=img' + nextImgSeq + ']';
element.style.display = 'none';
shownIMG = document.querySelector(nextImg);
shownIMG.style.display = 'block';
setTimeout(function() {
shownIMG.style.display = 'none';
showRandomImg();
}, 1000);
});
}
function showRandomImg() {
var randomIMG = returnRandomOddNum();
randomIMG = (randomIMG !== currentIMG) ? randomIMG : returnRandomOddNum();
currentIMG = randomIMG;
randomIMG = 'img[data-image-seq=img' + randomIMG + ']';
document.querySelector(randomIMG).style.display = 'block';
}
function returnRandomOddNum() {
var randomNum = Math.floor(Math.random() * imgs.length);
randomNum = (randomNum % 2 != 0) ? randomNum : randomNum + 1;
return randomNum;
}
.imgs-wrapper { position: relative; }
.imgs-wrapper { cursor: pointer; }
.hide-me { display: none; }
<div class="imgs-wrapper">
<img data-image-seq="img1" src="//dummyimage.com/150x50?text=egg">
