最近在做个人博客想做个相册，鼠标悬浮后出现个div并且鼠标移动到哪个相册，div跟随到哪个相片上。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<style type="text/css">
.imgCon {
float: left;
}
img {
display: block;
float: left;
margin: 0px;
padding: 0px;
300px;
height: 200px;
}
/*img:hover {
z-index: -2;
transform: scale(1.3);
transition: transform 2s;
}*/
.upimg {
position: relative;
300px;
height: 200px;
opacity: 0.6;
background-color: black;
/*display: none;*/
visibility: hidden;
transition: all 1s ease-in-out;
}
.hut {
600px;
margin-left: 300px;
}
</style>
</head>
<body>
<div class="hut" onmouseover="getposition()">
<div class="imgCon">
<img src="1.jpg" id="img1">
<div class="upimg" id="upimg"></div>
</div>
<img src="1.jpg" >
<img src="1.jpg" >
<img src="1.jpg" >
</div>
<script type="text/javascript">
function getposition() {
var e = event || window.event;
var scrollX = document.documentElement.scrollLeft || document.body.scrollLeft;
var scrollY = document.documentElement.scrollTop || document.body.scrollTop;
var x = e.pageX || e.clientX + scrollX
var y = e.pageY || e.clientY + scrollY;
var img = document.getElementById('img1')
var upimg = document.getElementById('upimg')
upimg.style.visibility = 'visible'
upimg.style.left = `${parseInt(x / 300) * 300 - 300}px`
upimg.style.top = `${parseInt(y / 200) * 200}px`
return { 'x': x, 'y': y };
}
</script>
</body>
</html>
上面给出了代码，首先是判断鼠标坐标xy，然后取整，设置悬浮div的坐标，然后通过设置transition来实现动画，很简单。欢迎指正
