到目前为止，我已经能够做到当光标悬停在 div 上时，正文中会出现背景图像。我需要为此添加淡入淡出动画。我一直在这里寻找解决方案，但无法解决它。我没有任何 JavaScript 经验。
enter code here
<script>
changeBgImage = () => {
document.body.style.backgroundImage = "url('../Images/Background/wraithback.jpg')";
console.log("working")
}
ogBgImage = () => {
document.body.style.backgroundImage = "url('../Images/Background/black.jpg')";
console.log("working")
}
</script>
<style>
body {
background-image: url('../Images/Background/black.jpg');
}
</style>
<body>
<div class="gwraith"><a href="../Legends/wraith.html ">
<img src="../Images/Legends_pics/wraithchibi.png" width="130vw" class="wraith"
onmouseover="changeBgImage();" onmouseout="ogBgImage();">
</a>
</body>
最佳答案
向 body 标记添加转换规则。同样的事情可以在 css 中完成，无需 javascript。
function changeBgImage() {
document.body.style.backgroundImage = "url('https://s1.1zoom.ru/big0/284/Summer_Pond_Fence_Trees_496376.jpg')";
}
function ogBgImage() {
document.body.style.backgroundImage = "url('https://pristor.ru/wp-content/uploads/2017/02/leto12.jpg')";
}body {
background-image: url('https://pristor.ru/wp-content/uploads/2017/02/leto12.jpg');
background-repeat: no-repeat;
background-size: cover;
transition: all 0.7s linear;
}<body>
<div class="gwraith">
<a href="../Legends/wraith.html">
<img src="https://begin-english.ru/img/word/refresh.jpg" width="130vw" class="wraith"
onmouseover="changeBgImage();" onmouseout="ogBgImage();">
</a>
</div>
