求代码：如果使弹出窗口的大小，随内容自动变化。

TRY:
<script language="javascript">
function autoResize(src)
{
function resizeOpenWin()
{
var srcElem = event.srcElement
if (document.resized)  return
window.setTimeout(function ()
{
window.resizeBy(srcElem.width-100, srcElem.height-100)
},1)
document.resized = true
}

var newbody = "<body style='margin:0px'><script>"+resizeOpenWin.toString()+"</"+"script><img src='"+src+"' onreadystatechange='resizeOpenWin()'></body>"
var newwin = window.open("", "", "width=100, height=100, toolbar=yes")
newwin.document.write(newbody)
newwin.document.close()
}
autoResize("http://www.v-ec.com/images/logo.gif")
</script>
