jQueryで異なるiframe内の関数を呼び出す

Question

1つのページで、2つのdivに2つの外部コンテンツを読み込みます（つまり、＃div1、＃div2）。コンテンツは同じサーブにあります。これを使用するには、次のスクリプトを使用します：

function sack(file) { 
    this.xmlhttp = null; 

    this.resetData = function() { 
     this.method = "POST"; 
     this.queryStringSeparator = "?"; 
     this.argumentSeparator = "&"; 
     this.URLString = ""; 
     this.encodeURIString = true; 
     this.execute = false; 
     this.element = null; 
     this.elementObj = null; 
     this.requestFile = file; 
     this.vars = new Object(); 
     this.responseStatus = new Array(2); 
    }; 

    this.resetFunctions = function() { 
     this.onLoading = function() { }; 
     this.onLoaded = function() { }; 
     this.onInteractive = function() { }; 
     this.onCompletion = function() { }; 
     this.onError = function() { }; 
     this.onFail = function() { }; 
    }; 

    this.reset = function() { 
     this.resetFunctions(); 
     this.resetData(); 
    }; 

    this.createAJAX = function() { 
     try { 
      this.xmlhttp = new ActiveXObject("Msxml2.XMLHTTP"); 
     } catch (e1) { 
      try { 
       this.xmlhttp = new ActiveXObject("Microsoft.XMLHTTP"); 
      } catch (e2) { 
       this.xmlhttp = null; 
      } 
     } 

     if (! this.xmlhttp) { 
      if (typeof XMLHttpRequest != "undefined") { 
       this.xmlhttp = new XMLHttpRequest();

    this.processURLString = function(string, encode) { 
     encoded = encodeURIComponent(this.argumentSeparator); 
     regexp = new RegExp(this.argumentSeparator + "|" + encoded); 
     varArray = string.split(regexp); 
     for (i = 0; i < varArray.length; i++){ 
      urlVars = varArray[i].split("="); 
      if (true == encode){ 
       this.encVar(urlVars[0], urlVars[1]); 
      } else { 
       this.setVar(urlVars[0], urlVars[1]); 
      } 
     } 
    } 

    this.createURLString = function(urlstring) { 
     if (this.encodeURIString && this.URLString.length) { 
      this.processURLString(this.URLString, true);

     } 

     // prevents caching of URLString 
     this.setVar("rndval", new Date().getTime()); 

     urlstringtemp = new Array(); 
     for (key in this.vars) {

      urlstringtemp[urlstringtemp.length] = key + "=" + this.vars[key][0]; 
     }

最初のdivにある関数を2番目のdivで呼び出すことはできますか？

Answer 1

2つのウィンドウ（フレームとiframe）が同じドメインにある場合は、関数を2つのウィンドウ（フレームとiframe）にまたがって呼び出すことができます。

function windowOneFunction(){ 
    //do something 
} 

ウィンドウ

windowOne.windowOneFunction() 

Answer 2

いいえ、これはSame origin policyの制限です。このような操作はできません。
