Iframe自适应高度统制

Iframe自适应高度控制

<iframe width="778" align="center" height="200" id="cwin" name="cwin" onload="Javascript:SetCwinHeight(this)" frameborder="0" scrolling="no"></iframe>

JS代码：

function SetCwinHeight(obj)
{
  var cwin=obj;
  if (document.getElementById)
  {
    if (cwin && !window.opera)
    {
      if (cwin.contentDocument && cwin.contentDocument.body.offsetHeight)
        cwin.height = cwin.contentDocument.body.offsetHeight; 
      else if(cwin.Document && cwin.Document.body.scrollHeight)
        cwin.height = cwin.Document.body.scrollHeight;
    }
  }
}

在iframe里面显示的页面，还要加点这样的样式控制：

<style type="text/css">
        html, body
        {
            overflow-x: hidden;
            overflow: auto;
            margin: 0px;
            height: 100%;
        }
    </style>
