这篇文章主要介绍了php main 与 iframe 相互通讯类(js+php同域/跨域),需要的朋友可以参考下

main 与 iframe 相互通讯类

今天把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"]']);

代码如下:

FrameMessage.exec('http://localhost/execA.php', '', 'fMain', ['programmer', '{"first":"PHP","second":"javascript"}', '["EEG","NMG"]']);
Copy after login

因部分浏览器不支持JSON.stringify 与JSON.parse 方法(如IE6/7),为了兼容,需要包含json2.js,下载地址:

  /* 执行方法

  frame  要调用的方法的框架名称,为空则为parent
  func   要调用的方法名
  args   要调用的方法的参数,必须为数组[arg1, arg2, arg3, argn...],方便apply调用
       元素为字符串格式,请不要使用html,考虑注入安全的问题会过滤
