我的任务
分享２００分解决有难度的图片缩放、拖动问题，看帖会有收获的
看了此贴恭喜你，不规则的图片热区鼠标经过样式以后不用愁了。
另外，因为我是要做地图，需要解决图片拖动和缩放的问题，当然是在热区不能去掉的情况下。
第一个解决问题的送100+分

研究中，DIV缩放图片能跟着缩放？

哦，忘记说了，你那个map.js有小问题：IE6下页面加载后热区就高亮了,需要改改

缩放也是一个道理，你只要把图片和热区用一个DIV容器装起来，操作这个容器就不会和你的map.js冲突了

测试了，相当不错。但是，几次放大缩小热区变形是个问题。建议：
设置全局变量initalData
var initalData={
W1: false,
H1: false，
coords1: new Array()
}
window.onload=function(){
//这里读取图片的尺寸，给initalData.W1/H1赋值；
。。。。。。。。。。
//读取各个area的coords属性给initalData.coords1赋值
。。。。。。。。。。
}
function aa(n){
var o=document.getElementById('ff');
document.getElementById("ff_canvas").innerHTML="";//将原来的热区去掉
cvi_map.remove(o);
var W1=initalData.W1;,H1=initalData.H1;
o.style.width=W1+10*n+'px';o.style.height=parseInt((o.offsetWidth/W1)*H1)+'px';
var W2=o.offsetWidth,H2=o.offsetHeight;
var rW=W2/W1, rH=H2/H1;
var areal=document.getElementsByTagName('area');
for (j=0;j<areal.length;j++){
var coords=document.getElementsByTagName('area')[j].getAttribute('coords');
var a=coords.split(',');
for(var i=0;i<a.length;i++){
a[i]=i%2==0?a[i]*rW:a[i]*rH;//这里不要加parseInt,因为数字太小的会变0，再放大热区就变形了
}
document.getElementsByTagName('area')[j].setAttribute('coords',a.join(','))
}
cvi_map.add(o,{areacolor: '#FFFF00', bordercolor: '#60F',nofade:'true' });
canvahtml=document.getElementById("ff_canvas").innerHTML;//加上新的热区
}
设置全局变量initalData
var initalData={
W1: false,
H1: false，
coords1: new Array()
}
window.onload=function(){
//这里读取图片的尺寸，给initalData.W1/H1赋值；

因为代码是你的不是我的，所以我就不仔细找了，哈哈。
还有，IE6下你的原版map.js就有个bug:页面初次加载，热区就自动加亮了；这倒也罢了，关键是缩放以后，它原来尺寸的高亮区还是有。我也没耐心再仔细找原因了，呵呵

/***************************缩放测试**************************************/
//已经成功缩放并且全部调整好，缩放后高亮也出现了。只是方法比较BT，你需要自己到map.js里找更好的方式
因为代码是你的不是我的，所以我就不仔细找了，哈哈。
还有，IE6下你的原版map.js就有个bug:页面初次加载，热区就自动加亮了；这倒也罢了，关键是缩放以后，它原来尺寸的高亮区还是有。我也没耐心再仔细找原因了，呵呵
