This article mainly introduces the JS implementation of a simple floating collision effect, which is similar to the effect of advertising floating images colliding back and forth on the screen. It involves related techniques for dynamically operating page element attributes using JavaScript combined with time. Friends who need it can refer to it
The example in this article describes how to implement a simple floating collision effect in JS. Share it with everyone for your reference, the details are as follows:
<html>
<head>
<meta charset="UTF-8">
<title>www.jb51.net JS碰撞效果</title>
<script language="javascript">
<!--
directX=1; //X轴方向
directY=1; //Y轴方向
sunX=0;
sunY=0;
function sunMov(){
//定两个方向
sunX+=directX*2;
sunY+=directY*2;
//修改p的left top
sunp.style.top=sunY+"px";
sunp.style.left=sunX+"px";
//判断什么时候，转变方向
//x方向(offestWidth可以返回，当前这个对象的实际宽度)
if(sunX+sunp.offsetWidth>=document.body.clientWidth || sunX<=0){
directX=-directX;
}
if(sunY+sunp.offsetHeight>=document.body.clientHeight || sunY<=0){
directY=-directY;
}
}
setInterval("sunMov()",10);
//-->
</script>
</head>
<body style="/*background-image:URL('a.jpg');background-size:cover; background-repeat:no-repeat*/">
<p id="sunp" style="position:absolute">
<img src="/static/imghwm/default1.png" data-src="//www.jb51.net/images/logo.gif" class="lazy" / alt="How to implement floating collision in JS" >
</p>
</body>
</html>Operation effect:
The above is what I compiled for everyone. I hope it will be helpful to everyone in the future. .
