Iframe和父窗口互调方法的集合
1.子iframe里调用父级的方法：window.parent.document.
2.父级里调用子集iframe：window.frames["iframe_text"].document.
下面是例子：
index.html
<HTML>
<HEAD>
<TITLE> Test Page </TITLE>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script src="prototype-1.4.0.js"></script>

function show()
{
window.frames["iframe_text"].document.getElementById("myH1").innerHTML = "http://hi.wonsoft.cn";
}
</script>
</HEAD>
<BODY>
<iframe height="350" width="600" src="iframe_test.html" name="iframe_text"></iframe>
