iframe 父窗口和子窗口相互的调用方法集锦，需要的朋友可以参考下。
一、父窗口调用iframe子窗口方法
1、HTML语法：<iframe name="myFrame" src="child.html"></iframe>
2、父窗口调用子窗口：myFrame.window.functionName();
3、子窗品调用父窗口：parent.functionName();
简单地说,也就是在子窗口中调用的变量或函数前加个parent.就行
4、父窗口页面源码：
<html>
<head>
<script type="text/javascript">
function say() {
alert("parent.html------>I'm at parent.html");
}
function callChild()
{
//document.frames("myFrame").f1();
myFrame.window.say();
}
</script>
</head>
<body>
<input type=button value="调用child.html中的函数say()" onclick="callChild()">
<iframe name="myFrame" src="child.html"></iframe>
</body>
</html>
<html>
<head>
<script type="text/">
function say()
{
alert("child.html--->I'm at child.html");
}
function callParent() {
parent.say();
}
</script>
</head>
<body>
<input type=button value="调用parent.html中的say()函数" onclick="callParent()">
</body>
</html>
<HTML>
<HEAD>

<script src="prototype-1.4.0."></script>
<script language="javascript">
function show()
{
window.frames["iframe_text"].document.getElementById("myH1").innerHTML = "";
}
</script>
</HEAD>
<BODY>
<iframe height="350" width="600" src="iframe_test.htm" name="iframe_text"></iframe>
<form action="" method="post">

<br />
<textarea cols="50" rows="5" id="getAttributeMethod"></textarea>
<input type="button" onClick="show();" value="提交"/>
</form>
<h1 id="myH1">d</h1>
</BODY>
</HTML>
