Question

How do i pass three arguments using external interface in flash to a java script function and get back output and display it in flash?

---

import flash.external.ExternalInterface; var para:Array = new Array(); send_btn.addEventListener(MouseEvent.CLICK, clickListener); function clickListener(eventObj:Object ):void {     para.push(mean.text);     para.push(std.text);     para.push(points.text);     trace('click > ' + para);     var output =ExternalInterface.call('calc',int(para[0]),int(para[1]),int(para[2]) ); out.text = output; } 

this is the code i am using to call a function calc which takes three arguments in java script, is this the right way of doing it and how can i get arguments back from javascript and display them in flash

AS3:

var percent:int = Math.round(100 * done/total);  // pass 3 arguments to javascript var result:Object = call('progress', { percent:percent, phase:'building', third:'baggage' });  // display what comes back label.text = 'js returned: ' + result.status; if (result.status == 'ack')     continue; //....  public function call(func:String, args:Object = null):Object {    // check to see if we're in a container    if (ExternalInterface.available)       return ExternalInterface.call(func, args);    else       return { status:'fail' }; } 

javascript:

<script> function progress(info) {     if (info.phase == 'building')          $('#status').html('Progress: ' + info.percent + '% done building');     //...     return { status:'ack' }; } </script>
