ExternalInterface

programming flash

I want to initialize a JS function when the swf loads. However, I can’t seem to get it to return the value. What am I doing wrong?


import flash.external.ExternalInterface;

var sending_lc:LocalConnection = new LocalConnection();
var thisresult:Object = ExternalInterface.call("initializedSend");
received_ti.text = "Returned: " + thisresult;
sending_lc.send("demoConnection", "printOut", thisresult);


function getTextFromJavaScript(str:String):Void {
 received_ti.text = "From JavaScript: " + str;
 sending_lc.send("demoConnection", "printOut", "from JS: "+str);
}

ExternalInterface.addCallback("sendTextToFlash", this, getTextFromJavaScript);


function clickSend(eventObj:Object):Void {
 var jsArgument:String = sending_ti.text;
 var myresult:Object = ExternalInterface.call("getTextFromFlash", jsArgument);
 received_ti.text = "Returned: " + myresult;
}
send_button.addEventListener("click", clickSend);
