如何实现无缝滚动

① JavaScript里面怎么让图片实现无缝横向滚动效果！！！

先了解一下对象的几个的属性： innerHTML:设置或获取位于对象起始和结束标签内的 HTML scrollHeight: 获取对象的滚动高度。 scrollLeft:设置或获取位于对象左边界和窗口中目前可见内容的最左端之间的距离 scrollTop:设置或获取位于对象最顶端和窗口中可见内容的最顶端之间的距离 scrollWidth:获取对象的滚动宽度 offsetHeight:获取对象相对于版面或由父坐标 offsetParent 属性指定的父坐标的高度 offsetLeft:获取对象相对于版面或由 offsetParent 属性指定的父坐标的计算左侧位置 offsetTop:获取对象相对于版面或由 offsetTop 属性指定的父坐标的计算顶端位置 offsetWidth:获取对象相对于版面或由父坐标 offsetParent 属性指定的父坐标的宽度 图片上无缝滚动 <style type="text/css"> <!-- #demo { background: #FFF;

② 【HTML】如何实现无缝循环的图片滚动效果

网站中，有时为了更好的利用有限的页面空间展示更多的内容，也为了丰富网站页面自身的表现样式，我们往往会用到图片滚动的效果。想要实现这种效果，只需要在想要显示的表格或网页中加入以下代码即可实现： <div id=demo style="overflow:hidden;height:100px;width:300px;"><table align=left cellpadding=0 cellspace=0 border=0><tr><td id=demo1 valign=top> <img height="150" alt="" width="200" src="/lazysite/user_space/7788/CIMG0056_缩小大小.JPG" /> <img height="150" alt="" width="200" src="/lazysite/user_space/7788/CIMG0053_缩小大小.JPG" /> <img height="150" alt="" width="200" src="/lazysite/user_space/7788/CIMG0054_缩小大小.JPG" /> <img height="150" alt="" width="200" src="/lazysite/user_space/7788/CIMG0058_缩小大小.JPG" /> <img height="200" alt="" width="150" src="/lazysite/user_space/7788/CIMG0059_缩小大小.JPG" /> <img height="150" alt="" width="200" src="/lazysite/user_space/7788/CIMG0063_缩小大小.JPG" /> <img height="150" alt="" width="200" src="/lazysite/user_space/7788/CIMG0070_缩小大小.JPG" /> <img height="150" alt="" width="200" src="/lazysite/user_space/7788/CIMG0071_缩小大小.JPG" /> <img height="150" alt="" width="200" src="/lazysite/user_space/7788/CIMG0072_缩小大小.JPG" /> //这个图片的地址可以是相对的也可以是绝对的 </td><td id=demo2 valign=top></td></tr></table></div><script>var speed=30 demo2.innerHTML=demo1.innerHTML function Marquee(){ if(demo2.offsetWidth-demo.scrollLeft<=0) demo.scrollLeft-=demo1.offsetWidthelse{demo.scrollLeft++}}var MyMar=setInterval(Marquee,speed) demo.onmouseover=function() {clearInterval(MyMar)} demo.onmouseout=function() {MyMar=setInterval(Marquee,speed)}</script>下面，我们就上面代码的主要部分进行分析： <div id=demo style="overflow:hidden;height:100px;width:300px;"> 这段代码中下划线的部分表示我们这段滚动图片所占用区域的大小。用户可根据页面的实际需要进行调节。但一般情况下至少要大于或等于图片的高度和宽度。 <img height="150" alt="" width="200" src="/lazysite/user_space/7788/CIMG0056_缩小大小.JPG" /> 上面这段代码是图片的代码。每加入一行如上代码，那就会多出一个展示的图片。图片可以是一个，也可以是无数个。需要强调的是，每个图片的高度和宽度应尽量的统一大小，主要显示出来的效果才会更好看。 var speed=30 这行代码是控制图片滚动的速度。数字越小，滚动的也就越快；相反，数字越大，滚动的也就越慢。
