让iframe自动适用高度JS代码
function SetCwinHeight(){ var bobo=document.getElementById("bobo"); //iframe id if (document.getElementById){    if (bobo && !window.opera){     if (bobo.contentDocument && bobo.contentDocument.body.offsetHeight){      bobo.height = bobo.contentDocument.body.offsetHeight+20;     }else if(bobo.Document && bobo.Document.body.scrollHeight){      bobo.height = bobo.Document.body.scrollHeight+20;     }    } } }

<iframe id="bobo" onload="Javascript:SetCwinHeight()" frameborder="0" scrolling="no" src="a.htm" allowtransparency="true"></iframe>
