我终于会使用iframe了！两个文件example.html和test.html，控制iframe里的内容：<?xml namespace="" ns="urn:schemas-microsoft-com:office:office" prefix="o" ?>
从父框架控制iframe
//example.html
<!DOCTYPE html PUBLIC "-//W<?xml namespace="" ns="urn:schemas-microsoft-com:office:smarttags" prefix="st1" ?>3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>标题栏</title>
</head>
<body>
<h1>
在此窗体中嵌入test.html</h1>
<iframe src="test.html" id="test" width="250" height="200" scrolling="no" frameborder="1">
</iframe>
<input type="button" id="btn1" name="btn1" value="ChangeInnerText..." onclick="javascript:frames('test').window.myH1.innerText='ffff'">
</body>
</html>
<?xml namespace="" ns="urn:schemas-microsoft-com:vml" prefix="v" ?>
嵌入的网页：
//test.html
<html>
<body>
<h1 id="myH1">
hello,my boy</h1>
</body>
</html>
点击按钮后：
还可以在主框架中取嵌入的页面中数据：
<input type="button" id="btn1" name="btn1"
value="FatchIframeText..." onclick="alert(frames('test').window.myH1.innerText)">
从iframe控制父框架
//example.html
<html>
<body onclick="alert(tt.myH1.innerHTML)">
<iframe name="tt" src="test.html" width="250" height="200" scrolling="no" frameborder="1">
</iframe>
<h1 id="myH2">
hello,my wife</h1>
<input type="button" id="btn1" name="btn1" value="button1" onclick="alert(tt.myH1.innerHTML)">
</body>
</html>
//test.html
<html>
<body>
<h1 id="myH1">
hello,my boy</h1>
<input type="button" id="btn2" name="btn2" value="ChangeParentText" onclick="parent.myH2.innerText='hello,my friend'">
<input type="button" id="btn3" name="btn3" value="ChangeParentHTML" onclick="parent.myH2.innerHTML='hello,my friend'">
</body>
</html>
主框架上的文字改变了。
