I am unable to get the callIFrameFunction method working. Below is my code snippet. Any help would be mich appreciated:-

I am calling a js function defined in my iframe source page:-

frame1.callIFrameFunction("clickMe");

In the html page, I have added the function:-

function clickMe() { alert('1'); }

But i dont get the alert. Please can anyone advice where I am going wrong.

Thanks

We need to fix this before upgrading to Flex 4.

I have found that I have to define JavaScript functions that I want to call inside the iframe source page as attached specifically to the document object (as this is how the callIFrameFunction code expects to find them)

So for your example above, try changing the JS function to be declared like this:

document.clickMe = function () { alert('1'); }

OK, I added an example for callIFrameFunction(): http://code.google.com/p/flex- iframe/source/browse/#svn/trunk/examples/CallIFrameFunction

As Ryan said, you have to declare the function this way:

document.myFunction = function () { // ... }

I have copy the example and test it.

The parameter function doesn' work on IE8, but the other two works fine. On Firefox works but when the alert appears, Firefox freeze. Everything works fine on Chrome.

anyone can help me to solve it?

The problem is that you are trying to target the document while your methods are on the window object. Try this code instead:

public static var INSERT_FUNCTION_CALLIFRAMEFUNCTION:String = "document.insertScript = function ()" + "{ " + "if (document." + FUNCTION_CALLIFRAMEFUNCTION + "==null)" + "{" + FUNCTION_CALLIFRAMEFUNCTION + " = function (iframeID, functionName, args)" + "{" + "var iframeRef=document.getElementById(iframeID);" + "var iframeWin;" + "if (iframeRef.contentWindow) {" + "iframeWin = iframeRef.contentWindow;" + "} else if (iframeRef.contentDocument) {" + "iframeWin = iframeRef.contentDocument.window;" + "} else if (iframeRef.window) {" + "iframeWin = iframeRef.windwo;" + "}" + "if (iframeWin.wrappedJSObject != undefined) {" + "iframeWin = iframeDoc.wrappedJSObject;" + "}" + "return iframeWinfunctionName;" + "}" + "}" + "}";

Last post works like a charm. Thanks! Note that the proposed code has a typo, “iframeWin = iframeRef.windwo;”, should be “iframeWin = iframeRef.window;”.
