『贰』 js实现图片左右滚动
根据楼上做了点修改，这是用jquery，所以一定要链接jquery库。
<html>
<head>
<title></title>
<styletype="text/css">
body,ul,li{list-style:noneoutsidenone;padding:0;margin:0;}
#picScroll{width:350px;overflow:hidden;}
ul{width:1000%;}
ulli{float:left;}
liimg{width:100px;height:100px;}
</style>
<scripttype="text/javascript"src="jquery-1.4.2.min.js"></script>
</head>
<body>
<divid="picScroll">
<ul>
<li>
<a><imgsrc="../pic/1.jpg"/></a>
<a><imgsrc="../pic/2.jpg"/></a>
<a><imgsrc="../pic/3.jpg"/></a>
<a><imgsrc="../pic/4.jpg"/></a>
<a><imgsrc="../pic/5.jpg"/></a>
</li>
<li></li>
</ul>
</div>
<scripttype="text/javascript">
vartarget=$('#picScroll');//其实标准的写法是var$target=$('#picScroll');
varleft=0;
varspeed=30;
varli=$('#picScrollulli');
li.eq(1).html(li.eq(0).html());//复制第一个li节点内容，赋值给第二个li目的是为了实现无限循环滚动
functionMarqeen(){
if(li[0].offsetWidth<=left){
left-=li[0].offsetWidth;
}
else{
left++;
}
target.scrollLeft(left);
}
$(function(){
varmarQueen=window.setInterval(Marqeen,speed);
target.mouseover(function(){
clearInterval(marQueen);
});
target.mouseout(function(){
marQueen=window.setInterval(Marqeen,speed);
});
});
</script>
</body>
</html>
下面是用 js 写的，不用连接jquery库了，可以对比一下上面的jquery代码
<scripttype="text/javascript">
vartarget=document.getElementById('picScroll');
varleft=0;
varspeed=30;
varLI=target.getElementsByTagName('li');
LI[1].innerHTML=LI[0].innerHTML;
functionMarqeen(){
if(LI[0].offsetWidth<=left){
left-=LI[0].offsetWidth;
}
else{
left++;
}
target.scrollLeft=left;
}
varmarQueen=window.setInterval(Marqeen,speed);
target.mouseover=function(){
clearInterval(marQueen);
};
target.mouseout=function(){
marQueen=window.setInterval(Marqeen,speed);};
</script>
『叁』 js中怎么实现图片不间断的向左滚动效果，要那种代码清晰的~
<script type="text/javascript">
var speed = 20;//滚动速度
var maq;
var m1;//第一份滚动的内容
var m2;//第二份滚动的内容
var timer;//定时器
function run(){
if(m1.offsetWidth<=maq.scrollLeft){
maq.scrollLeft-=m1.offsetWidth;
}else{
maq.scrollLeft+=6;
}
}
window.onload=function(){
maq=document.getElementById("maq");
m1=document.getElementById("m1");
m2=document.getElementById("m2");
m2.innerHTML=m1.innerHTML;
if(timer==null){
timer=window.setInterval(run,speed);
}
maq.onmouseover=function(){
window.clearInterval(timer);
}
maq.onmouseout=function(){
timer=window.setInterval(run,speed);
}
}
</script>
</head>
<body>
<div id="maq" style="height:200px; width:180px; overflow:hidden">
<table>
<tr>
<td id="m1">
<table>
<tr>
<td><img src="file:///E|/Images/player1.png" width="174" height="268" /></td>
<td><img src="file:///E|/Images/player2.png" width="174" height="268" /></td>
<td><img src="file:///E|/Images/player3.png" width="174" height="268" /></td>
</tr>
</table>
</td>
<td id="m2"></td>
</tr>
</table>
</div>
</body>
楼主详细代码在这里这已经是相当的简介版了你只要把图片路径改一下就能用了，~要采纳呦~你懂得~~
