大橙子啊啊啊啊 人气:0让一个div始终悬浮在右下角
<!DOCTYPE html>

<style>
#div1{
width: 100px;
height: 150px;
background: red;
position: absolute;
bottom: 0px;
right: 0px;
}
</style>
<script>
window.onscroll = function(){
var oDiv = document.getElementById('div1');
var scrollTop =document.documentElement.scrollTop||document.body.scrollTop;//浏览器兼容
startmove(document.documentElement.clientHeight - oDiv.offsetHeight + scrollTop)
// document.documentElement.clientHeight 页面可视区高度
}
var timer = null;
//悬浮框缓冲运动
function startmove(iTarget){
var oDiv = document.getElementById('div1');
clearInterval(timer);
timer = setInterval(function(){
var speed = (iTarget-oDiv.offsetTop)/4;
speed = speed>0?Math.ceil(speed):Math.floor(speed);
if(oDiv.offsetTop == iTarget){
clearInterval(timer);
}
else{
oDiv.style.top = oDiv.offsetTop +speed+'px';
}
},30)
}
</script>
</head>
<body style="height:2000px">
<div id="div1"></div>
</body>
</html>对联悬浮
让div悬浮在右侧中间
只需要更改start move()函数中的数据
startmove(parseInt((document.documentElement.clientHeight - oDiv.offsetHeight )/2)+ scrollTop)//对联悬浮
