如何在iframe外控制iframe中的css?
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="zh-CN">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312"/>
<title></title>
</head>
<body>
<iframe id="FF" src="B.htm"></iframe>
<input type="submit" value=" OK " onclick="OK()"/>
<script language="JavaScript">
function OK()
{
// 操作iframe中內容的CSS
var iframe = document.getElementByIdx('FF');
var body = iframe.contentWindow.document.body;
body.style.marginTop =50;
body.style.padding =0;
body.style.fontSize =30;
body.style.textAlign ='center';
body.style.backgroundColor ='red';
body.style.color ='blue';
}
</script>
</body>
</html>
這樣是可行的，前提是這個iframe是跟你的頁面在一個域內，如果跨域了 var iframe = document.getElementById('FF'); 就報錯“無存取權限”。
現在的問題就是跨域 怎麼修改iframe中的樣式。。待解決。。
