iframe自適應高度的實現

//JS函數

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

最後，加入iframe,不能丟掉onload屬性，當然了，id也必須也函數中的win匹配

<iframe width="778" align="center" height="200" id="win" name="win" οnlοad="Javascript:SetWinHeight(this)" frameborder="0" scrolling="no" src="1.htm"></iframe>
