asp.net图片实现轮换（后台读取图片链接路径）

asp.net图片实现轮换（后台读取图片链接路径）数据库

Answer 1

自己写的,所以没有注释,IE,火狐,OPERA,都能正常显示,希望对你能有帮助!图片数量可能自己更改!
我是把他单独存为forcepic.htm,放在js文件夹里的,然后在页面中调用的
以下是调用代码:

<div><script type="text/javascript" src="js/forcepic.htm"></script></div>

以下是轮换代码:
var widths=765;

var heights=210;

var counts=3;

img1=new Image ();img1.src='img/xuanchuan/x1.jpg';//换成数据库读取路径

img2=new Image ();img2.src='img/xuanchuan/x2.jpg';//换成数据库读取路径

img3=new Image ();img3.src='img/xuanchuan/x3.jpg';//换成数据库读取路径

url1=new Image ();url1.src='#';

url2=new Image ();url2.src='#';

url3=new Image ();url3.src='#';

var nn=1;

var key=0;

function change_img()

{if(key==0){key=1;}

else if(document.all)

{document.getElementById("pic").filters[0].Apply();document.getElementById("pic").filters[0].Play(duration=2);}

eval('document.getElementById("pic").src=img'+nn+'.src');

eval('document.getElementById("url").href=url'+nn+'.src');

for (var i=1;i<=counts;i++){document.getElementById("xxjdjj"+i).className='axx';}

document.getElementById("xxjdjj"+nn).className='bxx';

nn++;if(nn>counts){nn=1;}

tt=setTimeout('change_img()',4000);}

function changeimg(n){nn=n;window.clearInterval(tt);change_img();}

document.write('<style>');

document.write('.axx{padding:0px 7px 3px;*padding:1px 7px;border-left:#cccccc 1px solid;}');

document.write('a.axx:link,a.axx:visited{text-decoration:none;color:#fff;line-height:12px;font:9px sans-serif;background-color:#666;}');

document.write('a.axx:active,a.axx:hover{text-decoration:none;color:#fff;line-height:12px;font:9px sans-serif;background-color:#999;}');

document.write('.bxx{padding:0px 7px 3px;*padding:1px 7px;border-left:#cccccc 1px solid;}');

document.write('a.bxx:link,a.bxx:visited{text-decoration:none;color:#fff;line-height:12px;font:9px sans-serif;background-color:#D34600;}');

document.write('a.bxx:active,a.bxx:hover{text-decoration:none;color:#fff;line-height:12px;font:9px sans-serif;background-color:#D34600;}');

document.write('</style>');

document.write('<div style="width:'+widths+'px;height:'+heights+'px;overflow:hidden;text-overflow:clip;">');

document.write('<div><a id="url"><img id="pic" style="border:0px;filter:progid:dximagetransform.microsoft.wipe(gradientsize=1.0,wipestyle=4, motion=forward)" width='+widths+' height='+heights+' /></a></div>');

document.write('<div style="filter:alpha(style=1,opacity=10,finishOpacity=80);-moz-opacity:0.8; opacity:0.8;background: #888888;width:100%-2px;text-align:right;top:-12px;position:relative;margin:1px;height:12px;padding:0px;margin:0px;border:0px;">');

for(var i=1;i<counts+1;i++){document.write('<a href="javascript:changeimg('+i+');" id="xxjdjj'+i+'" class="axx" target="_self">'+i+'</a>');}

document.write('</div></div>');

change_img();

数据库循环输出脚本就能实现你要的效果了
