div跟随鼠标移动是依赖于鼠标移动事件(onmousemove),废话不多说直接上代码:
CSS:
<style>
#div1{
50px;
height:50px;
border-radius:25px;
background-color:rgba(0,0,0,0.5);
cursor:pointer;
position:absolute;
top:50%;
left:50%;
transform:translate(-50%,-50%)
}
</style>
HTML:
<div id="div1"></div>
JS:
<script>
document.onmousemove = function(ev){
var oEvent=ev||event;
var oDiv=document.getElementById('div1');
oDiv.style.left=oEvent.clientX+'px';
oDiv.style.top=oEvent.clientY+'px';
}
</script>
以上三部分搞定div跟随鼠标移动,非常简单。
