JS呼叫程式碼如下：
function jsFun() //被flex中的as方法呼叫
{
return "來自js";
}
function getFlexMsg() //呼叫flex中的as方法
{
var msg=document.getElementById("JSandFlex").getFlexMsg(); //說明：JSandFlex是html檔案中flash builder生成的swf物件的id，getFlexMsg是在flex中註冊的可被js呼叫的as方法別名
}
以上js程式碼可直接放在index.template.html的<head></head>內，也可放在單獨的檔案中然後在index.template.html中引用.
