IFrame Cross Domain Communication - FireFox?

55 New Member

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:

Expand|Select|Wrap|Line Numbers

  
Page1.html  

(http://localhost/app1/page1.html - app1 virtual dir on IIS)

----------------

<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();"/>
