在浏览网页时看到这样一个效果,感觉不错,但是看了半天也没明白它如何对图片进行处理的,不晓得其代码是如何获取要操作图片的联接的!本人对javascript不懂,只是想利用这个网页所用的效果来处理自己网页的上图片?望高手解惑与指导如何实现!不胜感谢!
http://www.wga.hu/frames-e.html?/html/a/abadia/index.html进这个网页点击那张小图可以进入那个实现了图片缩放的页面.(我要问的就是这个进入的页面的效果如何实现)点击小图后进入的页面地址是这个:http://www.wga.hu/support/viewer/z.html,但是直接从这个地址进入的话就看不到大图了,而是只有那些控制缩放的东东.
这个网站的首页是http://www.wga.hu,可以进去看看,不错的网站,可以查看到欧洲绘画大师的作品.
我在此粘贴一些我认为是的主要的代码,也不晓得是不是这些:

JAVAScript如何实现图片等比缩放!
以下是代码片段:
<script language="JavaScript">
<!--
//图片按比例缩放
var flag=false;
function DrawImage(ImgD){
var image=new Image();
var iwidth = 160; //定义允许图片宽度,当宽度大于这个值时等比例缩小
var iheight = 120; //定义允许图片高度,当宽度大于这个值时等比例缩小
image.src=ImgD.src;
if(image.width>0 && image.height>0){
flag=true;
if(image.width/image.height>= iwidth/iheight){
if(image.width>iwidth){
ImgD.width=iwidth;
ImgD.height=(image.height*iwidth)/image.width;
}else{
ImgD.width=image.width;
ImgD.height=image.height;
}ImgD.alt=image.width+"×"+image.height;
}
else{
if(image.height>iheight){
ImgD.height=iheight;
ImgD.width=(image.width*iheight)/image.height;
}else{
ImgD.width=image.width;
ImgD.height=image.height;
}
ImgD.alt=image.width+"×"+image.height;
}
}
}
//调用:<img src="图片" onload="javascript:DrawImage(this)">
//-->
</script><img src=”图片” onload=”javascript:DrawImage(this)”>onload=”javascript:DrawImage(this)”
这句增动你要缩小的图片的<img />中再把上面的函数加到
<head>
</head>
之间就可以了!var iwidth = 160; //定义允许图片宽度,当宽度大于这个值时等比例缩小
var iheight = 120; //定义允许图片高度,当宽度大于这个值时等比例缩小
这两个值是限制图片最大的宽度或高度,自己需要多大就改为多大
<html>
<head>
<title>Demotitle><meta http-equiv="Content-Type" content="text/html; charset=gb2312"><script language="JavaScript" type="text/JavaScript">
//改变图片大小
function resizepic(thispic)
{
if(thispic.width>700) thispic.width=700;
}
//无级缩放图片大小
function bbimg(o)
{
var zoom=parseInt(o.style.zoom, 10)||100;
zoom+=event.wheelDelta/12;
if (zoom>0) o.style.zoom=zoom+'%';
return false;
}
