如何在Flash的ExternalInterface和JavaScript之間傳遞信息？

Question

如何將使用Flash中的外部接口的三個參數傳遞給java腳本函數並獲取輸出並將其顯示在閃存中？

---

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; 
} 

這是我使用調用一個函數，計算這三個參數中的Java腳本代碼，這是做的正確的方式，我怎麼能得到的參數，從背面的JavaScript並顯示它們閃光燈

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" }; 
} 

的javascript：

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