网页框架自适应高度

<script >
  function autoResize()  {
    try  {
      document.all["inner"].style.height=inner.document.body.scrollHeight
    }
    catch(e){}
  }
</script>
<iframe name="inner" src="http://www.xuexibiji.cn" marginwidth="0" marginheight="0" frameborder="0" scrolling="no" width="100%" style="height:expression(1); aho:expression(autoResize())"   > 
</iframe>
<iframe name="temp" height="0"></iframe>
<!--一定要注意框架的name值和JS里统一 -->
