我们在制作网页时经常遇到广告悬浮问题,下面这个html5列子比较简单,但是能够解决问题!!

<html xmlns = “ http ://www.w3.org/1999/xhtml“ >
<head >
<meta http-equiv = ” Content-Type“ content = ” text / html; charset = utf-8“ />

<div class = “ img” id = “ sroling” >
<img src = “ ../../images/png-1783.png” />

<脚本 类型= “ text / javascript” >
var id = function(i){return document.getElementById(i)}
var scroll = function(i){
var space = id(i).offsetTop;
id(i).style.top = space +'px';
void function(){
var goTo = 0;
var roll = setInterval(function(){
var height = document.documentElement.scrollTop + document.body.scrollTop + space;
var top = parseInt(id(i).style.top);
goTo = height-parseInt((height-top)* 0.9);
id(i).style.top = goTo +'px';
}
// else {if(roll)clearInterval(roll);}
},12);
}()
}
scroll('sroling');
