本文仅限 flex builder 3.0 版本生成的 flex 项目。
在项目bin-debug文件夹中找到以.html结尾的文件， 该文件其实就是运行swf文件的htm网页。
修改如下几个地方：
红色部分是添加参数的地方，注意两处都必须写：
<script language="JavaScript" type="text/javascript">
<!--
// Version check for the Flash Player that has the ability to start Player Product Install (6.0r65)
var hasProductInstall = DetectFlashVer(6, 0, 65);
// Version check based upon the values defined in globals
var hasRequestedVersion = DetectFlashVer(requiredMajorVersion, requiredMinorVersion, requiredRevision);
if ( hasProductInstall && !hasRequestedVersion ) {
// DO NOT MODIFY THE FOLLOWING FOUR LINES
// Location visited after installation is complete if installation is required
var MMPlayerType = (isIE == true) ? "ActiveX" : "PlugIn";
var MMredirectURL = window.location;
document.title = document.title.slice(0, 47) + " - Flash Player Installation";
var MMdoctitle = document.title;
AC_FL_RunContent(
"src", "playerProductInstall",

);
} else if (hasRequestedVersion) {
// if we've detected an acceptable version
// embed the Flash Content SWF when all tests are passed
AC_FL_RunContent(

} else { // flash is too old or we can't detect the plugin
var alternateContent = 'Alternate HTML content should be placed here. '
+ 'This content requires the Adobe Flash Player. '
+ '<a href=http://www.adobe.com/go/getflash/>Get Flash</a>';
document.write(alternateContent); // insert non-flash content
}
// -->
</script>
<!--显示swf的标签，可以不做改动，注意如果在这里添加参数，可能swf中无法获取该参数-->

在actionscript 中获取着这两个参数：
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" applicationComplete="onInit()">
<mx:Script>
<![CDATA[
import mx.controls.Alert;
private function onInit():void
{
if (stage){ // 如果上面红色地方 是creationComplete=="onInit()" ，那么stage可能为空
var param:Object = stage.loaderInfo.parameters;
//或者 // var param:Object = Application.application.parameters;
// "FlashVars","para1=happy2005",
if(param){
Alert.show(param.para1);
}
}
}
]]>
</mx:Script>
</mx:Application>
