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"]']);

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:

FrameMessage.js


/** Main 与 Iframe 相互通讯类 支持同域与跨域通讯

*/
var FrameMessage = (function(){

  this.oFrameMessageExec = null; // 临时iframe

  /* 执行方法
  executor 执行的页面,为空则为同域
  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
  */
  this.exec = function(executor, frame, func, args){

    this.executor = typeof(executor)!='undefined'? executor : '';
    this.frame = typeof(frame)!='undefined'? frame : '';
    this.func = typeof(func)!='undefined'? func : '';
    this.args = typeof(args)!='undefined'? (__fIsArray(args)? args : []) : []; // 必须是数组

    if(executor==''){
      __fSameDomainExec(); // same domain
    }else{

    }

  }

  /* 同域执行 */

      document.body.appendChild(this.oFrameMessageExec);
    }else{
      this.oFrameMessageExec.src = __fGetSrc();
    }
  }

  /* 获取执行的url */
  function __fGetSrc(){
    return this.executor + (this.executor.indexOf('?')==-1? '?' : '&') + 'frame=' + this.frame + '&func=' + this.func + '&args=' + JSON.stringify(this.args) + '&framemessage_rand=' + Math.random();
  }

  /* 判断是否数组 */
  function __fIsArray(obj){
    return Object.prototype.toString.call(obj) === '[object Array]';
  }

  return this;
