我有一张图片,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。我正在尝试在单击时在两个图像之间添加平滑过渡。

我试图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,但我不知道如何在 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。

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1">

<style>
.slidecontainer {
width: 100%;
opacity: 0;
transition: opacity .3s cubic-bezier(.4, 0, .2, 1);
}

.slider {
-webkit-appearance: none;
width: 100px;
height: 15px;
border-radius: 5px;
background: #d3d3d3;
outline: none;
-webkit-transition: .2s;
transition: opacity .2s;
position: relative;
}



.slider::-webkit-slider-thumb {
-webkit-appearance: none;
appearance: none;
width: 25px;
height: 25px;
border-radius: 50%;
background: #4CAF50;
cursor: pointer;
}

.slider::-moz-range-thumb {
width: 25px;
height: 25px;
border-radius: 50%;
background: #4CAF50;
cursor: pointer;
}

.slidecontainer:hover, img:hover + .slidecontainer {
opacity: 1;
}
</style>

<img id="Lightning" src="https://static.wixstatic.com/media/38d0c2_1f8b71c0bf644137ab295604ceaaecaa~mv2.png" height="100" width="100">

<div class="slidecontainer">
<input type="range" min="0" max="100" value="100" class="slider" id="volume">
</div>

<audio id="Thunder" loop>
<source src="http://music.wixstatic.com/preview/38d0c2_064b409cb5594774ab3c1fa24f9afa2f-128.mp3" type="audio/wav" />
</audio>

<script type="text/javascript">

function LightningChange() {
if (Lightning.src == "https://static.wixstatic.com/media/38d0c2_1f8b71c0bf644137ab295604ceaaecaa~mv2.png") {
Lightning.src = "https://static.wixstatic.com/media/38d0c2_5609c3592b894208b679ce8641031ae8~mv2.png";
} else {
Lightning.src = "https://static.wixstatic.com/media/38d0c2_1f8b71c0bf644137ab295604ceaaecaa~mv2.png";
}}

document.getElementById("Lightning").onclick = function() {
LightningChange()
var thunderAudio = document.getElementById("Thunder");
if (thunderAudio.paused) thunderAudio.play();
else thunderAudio.pause();
};

volume.addEventListener("mousemove", thunderVolume);

function thunderVolume(){
document.getElementById("Thunder").volume = document.getElementById("volume").value / 100;
}
</script>

最佳答案

我做到了,将两张图片放在一起,并在点击时更改其样式

<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");
};
</script>
