我有一张图像，点击后会发生变化。我通过在单击时更改图像的 src 来做到这一点。我试图在单击时在两个图像之间添加平滑过渡。
我尝试将两个图像放在彼此的顶部，并在单击时更改顶部图像的不透明度，但我无法弄清楚如何在 JavaScript 中更改不透明度，所以我放弃了这个想法，以防万一更简单的方法。

最佳答案
我将两个图像放在一起并在单击时更改其样式
<style>
.imageContainer{
position: absolute;
}
.hide{
visibility: hidden;
opacity: 0;
transition: opacity .5s, visibility .5s;
}
.visible{
visibility: visible;
opacity: 1;
}
</style>
<div id="Lightning" class="container">
<img class="imageContainer visible" src="https://static.wixstatic.com/media/38d0c2_1f8b71c0bf644137ab295604ceaaecaa~mv2.png" height="100" width="100">
<img id="secondImg" class="imageContainer hide" src="https://static.wixstatic.com/media/38d0c2_5609c3592b894208b679ce8641031ae8~mv2.png" height="100" width="100">
</div>
<script type="text/javascript">
document.getElementById("Lightning").onclick = function() {
document.getElementById("secondImg").classList.add("visible");
};
