iframe 与主框架相互访问方法

1.同域相互访问

假设A.html 与 b.html domain都是localhost （同域）
A.html中iframe 嵌入 B.html，name=myframe
A.html有js function fMain()
B.html有js function fIframe()
需要实现 A.html 调用 B.html 的 fIframe()，B.html 调用 A.html 的 fMain()

A.html

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 
<html> 
 <head> 
 <meta http-equiv="content-type" content="text/html; charset=utf-8"> 
 <title> main window </title> 
 
 <script type="text/javascript"> 
 // main js function 
 function fMain(){ 
 alert('main function execute success'); 
 } 
 
 // exec iframe function 
 function exec_iframe(){ 
 window.myframe.fIframe(); 
 } 
 </script> 
 
 </head> 
 
 <body> 
 <p>A.html main</p> 
 <p><input type="button" value="exec iframe function" onclick="exec_iframe()"></p> 
 <iframe src="B.html" name="myframe" width="500" height="100"></iframe> 
 </body> 
</html>
Copy after login

B.html

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 
<html> 
 <head> 
 <meta http-equiv="content-type" content="text/html; charset=utf-8"> 
 <title> iframe window </title> 
 
 <script type="text/javascript"> 
 // iframe js function 
 function fIframe(){ 
 alert('iframe function execute success'); 
 } 
 
 // exec main function 
 function exec_main(){ 
 parent.fMain(); 
 } 
 </script> 
 
 </head> 
 
 <body> 
 <p>B.html iframe</p> 
 <p><input type="button" value="exec main function" onclick="exec_main()"></p> 
 </body> 
</html>
Copy after login

点击A.html 的 exec iframe function button，执行成功，弹出iframe function execute success。如下图

点击B.html 的 exec main function button，执行成功，弹出 main function execute success。如下图

2.跨域互相访问

假设 A.html domain是 localhost， B.html domain 是 127.0.0.1 （跨域）
这里使用 localhost 与 127.0.0.1 只是方便测试，localhost 与 127.0.0.1已经不同一个域，因此执行效果是一样的。
实际使用时换成 www.domaina.com 与 www.domainb.com 即可。
A.html中iframe 嵌入 B.html，name=myframe
A.html有js function fMain()
B.html有js function fIframe()
需要实现 A.html 调用 B.html 的 fIframe()，B.html 调用 A.html 的 fMain() （跨域调用）

如果使用上面同域的方法，浏览器判断A.html 与 B.html 不同域，会有错误提示。
Uncaught SecurityError: Blocked a frame with origin "http://localhost" from accessing a frame with origin "http://127.0.0.1". Protocols, domains, and ports must match.

实现原理：
因为浏览器为了安全，禁止了不同域访问。因此只要调用与执行的双方是同域则可以相互访问。

首先，A.html 如何调用B.html的 fIframe方法
1.在A.html 创建一个 iframe
2.iframe的页面放在 B.html 同域下，命名为execB.html
3.execB.html 里有调用B.html fIframe方法的js调用

<script type="text/javascript"> 
parent.window.myframe.fIframe(); // execute parent myframe fIframe function 
</script>
Copy after login

这样A.html 就能通过 execB.html 调用 B.html 的 fIframe 方法了。

同理，B.html 需要调用A.html fMain方法，需要在B.html 嵌入与A.html 同域的 execA.html
execA.html 里有调用 A.html fMain 方法的js 调用

<script type="text/javascript"> 
parent.parent.fMain(); // execute main function 
</script>
Copy after login

这样就能实现 A.html 与 B.html 跨域相互调用。

A.html

执行如下图：

php main 与 iframe 相互通讯类(同域/跨域)
把main与iframe相互通讯的方法封装成类，主要有两个文件，
JS：FrameMessage.js 实现调用方法的接口，如跨域则创建临时iframe，调用同域执行者。
PHP：FrameMessage.class.php 实现接收到跨域请求时，根据参数返回执行方法的JS code。

功能如下：
1.支持同域与跨域通讯
2.传递的方法参数支持字符串，JSON，数组等。

复制代码 代码如下:
FrameMessage.exec('http://127.0.0.1/execB.php', 'myframe', 'fIframe', ['fdipzone', '{"gender":"male","age":"29"}', '["http://blog.csdn.net/fdipzone", "http://weibo.com/fdipzone"]']);
