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>??
5、子窗口页面:
<html>???
<head>???
<script type="text/javascript">
??????
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>
二、iframe 父窗口和子窗口相互的调用方法
1、IE中使用方法:
父窗口调用子窗口:iframe_ID.iframe_document_object.object_attribute = attribute_value
例子:onClick="iframe_text.myH1.innerText='http://www.pint.com';"
子窗口调用父窗口:parent.parent_document_object.object_attribute = attribute_value
例子:onclick="parent.myH1.innerText='http://www.pint.com';"
2、Firefox中使用方法:
上面在IE下没有问题,但在firefox下不正常。在firefox下,应该是如下调用方法:
父窗口调用子窗口:window.frames["iframe_ID"].document.getElementById("iframe_document_object"-).object_attribute = attribute_value
例: window.frames["iframe_text"].document.getElementById("myH1").innerHTML= "http://hi.wonsoft.cn";
子窗口调用父窗口:parent.document.getElementById("parent_document_object").object_attribute = attribute_value
例: parent.document.getElementById("myH1").innerHTML = "http://wonsoft.cn";

test.htm里面firefox下访问iframe 必须用name,不能用id,所以要改为name="iframe_test" 。(http://chenling1018.blog.163.com/blog/static/1480254200811891041694/)
