ExternalInterface.addCallback

Report · Dec 13, 2011

when communicating with flash from javascript is there a special setup that is required for flash.

the function in my actionscript (flash) is never called (the trace is never executed). i have been

searching for examples and help and everything i read looks like this should work.

all i am trying to do is send a text string to flash from javascript.

can anyone help me on this?

thanks

ACTIONSCRIPT 3.0 (code)

i have a flash program with just a dynamic text item named myTxt.

import flash.external.ExternalInterface;

import flash.display.*;

if (ExternalInterface.available) {

trace("external call okay");

ExternalInterface.addCallback("sendTextToAS3", receiveTextFromJS);

}

//Set up Javascript to Actioscript

function receiveTextFromJS(t:String):void {

trace('here');

myTxt.text = t;

}

HTML - JAVASCRIPT (code)

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<head>

// get our flash movie object

var flashMovie;

function init() {

if (document.getElementById) {

flashMovie = document.getElementById("flashDIV");

}

// wait for the page to fully load before initializing

window.onload = init;

function sendTextToAS3(){

alert ('send');

var Txt = document.getElementById('htmlText').value;

alert ('send ' +Txt);

flash.sendTextFromJS(Txt);

}

var flashvars = {};

var params = {};

params.allowscriptaccess = "always";

params.swliveconnect = "true";

var attributes = { id: "fvars1", name: "fvars1" };

swfobject.embedSWF("fvars1.swf", "flashDIV", "800", "600", "9.0.0", false, flashvars, params, attributes);

</script>

</head>

<body>

</a>

</div>

</body>

</html>

with addCallBack() yes, there is special javascript that needs to be used. to be sure:

flash.sendTextFromJS(Txt);

isn't correct. it's possible

flashMovie.sendTextFromJS(Txt);

might work but i doubt it. you should check the flash help files for sample code.

try:

function sendTextToAS3(){

var Txt = document.getElementById('htmlText').value;

alert ('send ' +Txt);

document.getElementById("fvars1").sendTextFromJS(Txt);

}

then try:

function sendTextToAS3(){
var Txt = document.getElementById('htmlText').value;
alert ('send ' +Txt);
document.getElementById("flashDIV").sendTextFromJS(Txt);
}

p.s. actually, assigning two different id's for the same div may be a problem. use one of the other id values but not two different ones.
