php main 与 iframe 相互通讯类(js+php同域/跨域)
main 与 iframe 相互通讯类
之前写过一篇《iframe与主框架跨域相互访问方法》,介绍了main与iframe相互通讯的原理,不了解原理的可以先看看。
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。
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"]']);
FrameMessage.exec('http://localhost/execA.php', '', 'fMain', ['programmer', '{"first":"PHP","second":"javascript"}', '["EEG","NMG"]']);
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:
