======================================
iframe标签的高度怎么样才能自适应src的页面？
例如：<iframe id=box2 name="cok" src="agree.htm" width="100%" scrolling="no" frameborder="0" marginwidth="0" marginheight="0" ></iframe>
这个iframe的高度怎么能自适应agree.htm的高度600？
不要告诉我设为height=600,因为这个iframe要应用几个高度不同的页面!
谢谢，找到了
<script>
function autoResize()
{
try
{
document.all["test"].style.height=test.document.body.scrollHeight
}
catch(e){}
}
</script>
<iframe id=test style="height:expression(1); aho:expression(autoResize())" src="\\"></iframe>
