Flex與Html交互獲得參數

包含swf的html頁面

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
    id="${application}" width="${width}" height="${height}"

    codebase="http://fpdownload.macromedia.com/get/flashplayer/current/swflash.cab">
    <param name="movie" value="${swf}.swf" />
    <param name="quality" value="high" />
    <param name="bgcolor" value="${bgcolor}" />
    <param name="allowScriptAccess" value="sameDomain" />
    <param name="FlashVars" value="param1=one&param2=2&param3=3&param4=four" />
    <embed src="${swf}.swf" quality="high" bgcolor="${bgcolor}"
        width="${width}" height="${height}" name="${application}" align="middle"
        play="true"
        loop="false"
        quality="high"
        allowScriptAccess="sameDomain"
        type="application/x-shockwave-flash"
        pluginspage="http://www.adobe.com/go/getflashplayer"
        FlashVars="param1=one&param2=2&param3=3&param4=four"
    </embed>
</object>

這裏關鍵是FlashVars="param1=one&param2=2&param3=3&param4=four"
這FlashVars把參數傳給了swf文件

private function onCreationComplete() : void
{
    var parameters : Object = Application.application.parameters;
    var param1 : String = parameters.param1;
    var param2 : int = parseInt( parameters.param2 );
    var param3 : int = parseInt( parameters.param3 );
    var param4 : String = parameters.param4;

    output.text = "param1: " + param1 + "/n" +
                  "param2: " + param2 + "/n" +
                  "param3: " + param3 + "/n" +
                  "param4: " + param4;
}

在flex中用Application.application.parameters來獲取上面所傳的參數
