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)：

 
                 
        <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)：

"quality" "high" />

"bgcolor" "#ffffff" />

"allowScriptAccess" "sameDomain" />

"allowFullScreen" "true" />

><param name= "flashvars" "var1=aabb&var2=ccdd" />

</span> 

/>

<p>

Either scripts and active content are not permitted to run or Adobe Flash Player version

10.0 or greater not installed.

</p>

<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>

</object>

在Flash中接收网页传递过来的参数

<?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>

</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;

Flex4 中将网页的参数传递给Flash，并且在Flash中读取这些参数
