Referencing The Html Object That Made The Externalinterface.call To The Javascript Function Called

i apologize if my terminology is off, my actionscript skills are pretty weak sauce. so, i have some actionscript that makes a ExternalInterface.call('someFunction'); call. is it po

Solution 1:

I guess you are talking about ExternalInterface.objectID. This property returns an id associated with flash container in object or embed tag.

I suggest that you should also pass the name of "someCallback" to you JS method. This way there will be no need to hardcode it in JS.

Here's an example

// Actionscript sourceconstjsMethodName:String = "someFunction";
constasCallbackName:String = "someCallback";
ExternalInterface.call(jsMethodName+"(document.getElementById("++")"++");");
ExternalInterface.addCallback(asCallbackName,someASfunction);

// Javascript sourcefunctionsomeFunction(flashId, callbackName) 
{
    var flashContainer = document.getElementById(flashId);
    flashContainer["callbackName"]();
}

EDIT: If you really want to get a reference to flash DOM object in someFunction arguments, you may achieve it in a bit tricky way (I would rather not, but just for your interest).

// Actionscript sourceconstjsMethodName:String = "someFunction";
constasCallbackName:String = "someCallback";
ExternalInterface.addCallback(asCallbackName,someASfunction);

ExternalInterface.call(
    "function(){"+ 
        jsMethodName+"("+
            "document.getElementById('"+ExternalInterface.objectID+"'),"+
            "'"+asCallbackName+"'"+
        ");"+
    "}"
);    

// Javascript sourcefunctionsomeFunction(flashContainer, callbackName) 
{
    flashContainer[callbackName]();
}

This way you inject some JS code from flash into js. It works, but looks messy.
