Flex4 中将网页的参数传递给Flash，并且在Flash中读取这些参数

使用Flash Builder 4创建Flex应用，会自动生成网页调用Flash，会有两种方式显示Flash，下面针对这两个方式看看如何添加参数。

方式一(swfobject)：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

<script type= "text/javascript" >              <!-- For version detection, set  to min. required Flash Player version,or 0  (or 0.0 . 0 ),255)!important; background:none!important">for  no version detection. -->              var  swfVersionStr = "10.0.0" ; <!-- To use  express install,monospace!important; min-height:inherit!important; background:none!important">to playerProductInstall.swf,otherwise the empty string. --> xiSwfUrlStr = "playerProductInstall.swf" ; <span style= "color: #000000;" > flash var s = { 1: "abc" , 2: "def" }; </span>            params = {}; params.quality = "high" ; params.bgcolor = "#ffffff" ; params.allowscriptaccess = "sameDomain" ; params.allowfullscreen = "true" ; attributes = {}; attributes.id = "test39" ; attributes.name = ; attributes.align = "middle" ; swfobject.embedSWF(                  "test39.swf" ottom:auto!important; float:none!important; height:auto!important; left:auto!important; line-height:1.8em!important; margin:0px!important; outline:rgb(0, "flashContent" ottom:auto!important; float:none!important; height:auto!important; left:auto!important; line-height:1.8em!important; margin:0px!important; outline:rgb(0, "100%" ottom:auto!important; float:none!important; height:auto!important; left:auto!important; line-height:1.8em!important; margin:0px!important; outline:rgb(0,                  swfVersionStr,xiSwfUrlStr, s,params,attributes); <!-- JavaScript enabled so display the flashContent div in  case  it is  not replaced with  a swf object. --> swfobject.createCSS( "#flashContent" "display:block;text-align:left;" ); </script>

方式二(html)：

<object classid= "clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"  width= "100%"  height= id= <param name= "movie"  value= "demo1.swf"  /> "quality"  "high"  /> "bgcolor"  "#ffffff"  /> "allowScriptAccess"  "sameDomain"  /> "allowFullScreen"  "true"  /> ><param name= "flashvars"  "var1=aabb&var2=ccdd"  /> </span>                <!--[ if  !IE]>--> <object type= "application/x-shockwave-flash"  data= >                      /> /> /> /> /> <!--<![endif]--> <!--[ gte IE 6 ]>--> <p>                          Either scripts and active content are not permitted to run or Adobe Flash Player version                          10.0 or greater not installed. </p> <!--<![endif]--> <a href= "http://www.adobe.com/go/getflashplayer" > <img src= "http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif"  alt= "Get Adobe Flash Player"  /> </a> !IE]>--> </object> <!--<![endif]--> </object>

<?xml version= "1.0"  encoding= "utf-8" ?> <s:Application xmlns:fx= "http://ns.adobe.com/mxml/2009"                 xmlns:s= "library://ns.adobe.com/flex/spark" xmlns:mx= library://ns.adobe.com/flex/mx"  minWidth= "955"  minHeight= "600"  creationComplete= "application1_creationCompleteHandler(event)"  pageTitle= >      <s:layout> <s:BasicLayout/> </s:layout> <fx:Script> <![CDATA[              import  mx.core.FlexGlobals; mx.events.FlexEvent;   protected  function  application1_creationCompleteHandler(event:FlexEvent): void { para: Object  = FlexGlobals.topLevelApplication.parameters; </span>             text1.text = para. 1; text2.text = para. 2; }   ]]> </fx:Script> <fx:Declarations> <!-- 将非可视元素（例如服务、值对象）放在此处 --> </fx:Declarations> <s:TextInput id= "text1"  x= "190"  y= "93" /> "text2"  "142" /> <s:Label x= "147"  "94"  text= "var1:" /> "142"  "var2:" /> </s:Application>

参数在Flex4的获取方式跟Flex3是不一样的：

Flex3:  var params:Object = Application.application.parameters; 

Flex4:  var params:Object = FlexGlobals.topLevelApplication.parameters;
