求帮我添加一个JS放大镜效果
JS放大镜效果，lz注意下编码问题，图片自己替换 !DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" " " html xmlns=" " head title超逼真的JS图片放大镜/title meta http-equiv="Content-Type" content="text/html; charset=utf-8" / style type="text/css" .zoomPan{width:570px;left:100px;position:relative; } .sh{zoom:1;background:#eee;filter:progid:DXImageTransform.Microsoft.dropShadow(color='#54000000', OffX=2,OffY=2);-webkit-box-shadow:4px 4px 4px #666;-moz-box-shadow:4px 4px 4px #666;} #zoom{position:absolute;width:254px;height:254px;border:3px solid #fff;left:-9999px;top:0;overflow:hidden;background:#fff;} #zoom img{position:relative;} h1{color:#FF0080;border-bottom:5px solid #ddd;padding:10px;} h4{text-align:right;padding:20px;border-top:1px solid #ddd;color:#ccc;} /style /head body h1zoom/h1 div class="zoomPan" id="zoomPan" img src="/jscss/demoimg/201008/s.jpg" alt="" / div id="zoom" class="sh"img src="/jscss/demoimg/201008/b.jpg" alt="" //div /div h4code.js.cn/h4 /body script type="text/javascript" //![CDATA[ function zoomBox() {this.index.apply(this, arguments)} zoomBox.prototype = { index: function(win,zoom) { var win=document.getElementById(win); var box=document.getElementById(zoom); var img=box.getElementsByTagName('IMG')[0]; var zoom=img.width/win.getElementsByTagName('IMG')[0].width; var z=Math.round(box.offsetWidth/2); win.onmousemove=function (e){ e = e || window.event; var x=e.clientX,y=e.clientY, ori=win.getBoundingClientRect(); if (xori.right+20||yori.bottom+20||xori.left-20||yori.top-20)box.style.display='none'; x-=ori.left; y-=ori.top; box.style.left=x-z+'px'; box.style.top=y-z+'px'; img.style.left=-x*zoom+z+'px'; img.style.top=-y*zoom+z+'px'; } win.onmouseover=function (){box.style.display=''} } }; window.onload=function (){ x=new zoomBox('zoomPan','zoom') } //]] /script /html
javascript放大镜代码
同命相连，我也在找这个效果，失望啊！
发现有教程，可是运行不起来，看你会吗？

求一个简单的点击图片放大缩小的JS代码
1、准备好需要用到的图标。
2、新建html文档。
3、书写hmtl代码。div id=allbox div id=boxhome img style="WIDTH: 107px; BOTTOM: 5px; HEIGHT: 176px; LEFT: 10px" id=imgSmallLeft class=imgBorder onClick="clearInterval(autoplay);moveD('l');" 。
4、书写并添加js代码。script src="js/ntes_jslib_1.x.js"/scriptscript src="js/zzsc.js"/script。
5、代码整体结构。
6、查看效果。
