    IFrame Cross Domain Communication - FireFox?

    Hello

    Can anyone here please guide me with the Cross Domain Communication between IFrames.

    Problem:

    Application1 running on IIS => http://localhost.ad.lo cal/Applicaiton1
    Application2 running on Apache => http://localhost.ad.lo cal:8080/Application2

    The Application2 is being loaded in an IFrame inside Application1; and there needed a communication beetween the two Applications. With IE my application works but with FireFox it doesnt.

    I have tried with several available tips like changing the document.domain property etc., but it doesnt seems to work. I am not able to get the objects from Application2 which is in an IFrame.

    Can anyone please guid me with this issue.

    Thanks & regards,
    Hash

      firefox provides several ways to communicate between cross-domain frames.

      look into postMessage and window.name specifically.

              Hi Carmarri !

              I created test pages.
              1. Page1.html calls Page2.html in an Iframe.
              2. Page1.html is hosted on IIS
              3. Page2.html is hosted on Apache
              4. Now i want to access a variable named "aTestVaria ble" of Page2 from Page1.
              5. This works perfectly in IE, but the problem is in FireFox.

              Thanks !

              Code as follows:

              Code:
              Page1.html  
([B][url]http://localhost/app1/page1.html[/url] - app1 virtual dir on IIS[/B])
----------------
<html>
<head>
<title></title>
<script type="text/javascript" language="JavaScript">

function checkIframeVar() {
     var IframeMap = parent.document.getElementById('IframeContainer"');
    //alert("IframeMap.contentWindow = " + IframeMap.contentWindow);
    alert("IframeMap.contentWindow.aTestVariable = " + IframeMap.contentWindow.aTestVariable);

}

</script>
</head>

<body>

<h1>Welcome</h1></br>
<div>Parent Page</div> <br>
<iframe id="IframeContainer" width="562" height="522" src="http://localhost:8080/app2/page2.html"></iframe>
<input type="button" value="CallGlobalVar" onclick="checkIframeVar();"/>

</body>
</html>
              Code:
              Page2.html 
([B][url]http://localhost:8080/app2/page2.html[/url] - app2 Virtual dir on Apache[/B])
-----------
<html>
<head>
<title>Iframe Child</title>

<script type="text/javascript" language="JavaScript">    

var aTestVariable = "H e l l o";

</script>
</head>
<body>
    <h1>H E L L O </h1> </br>
    <div id='poDiv'>
	WebPage in IFrame
    </div>
</body>
</html>
