Question

我有一个1.2mb的闪光swf。我使用动态嵌入将其与swfobject一起嵌入。

<script type="text/javascript">
var flashvars = {};

flashvars.campaignid = "12345678890";
var params = {};
params.allowscriptaccess = "always";
var attributes = {};
swfobject.embedSWF("soccer.swf", "myAlternativeContent", "550", "400", "10.0.0", false, flashvars, params, attributes);
</script>

在我的文档类中读取campaignid ...

代码就像

public function Main()
{    
    loaderInfo.addEventListener(ProgressEvent.PROGRESS,update); 
    loaderInfo.addEventListener(Event.COMPLETE,onLoadedMovie); 
}                 
private function update(e:ProgressEvent):void         
{
}

private function onLoadedMovie(e:Event)
{
    campId=this.root.loaderInfo.parameters["campaignid"]; 
}

当我提醒值时，我得到了null 当我在一个小文件中使用相同的方法时，它的工作原理.. 谁能帮我？问候

Answer 1

我通过在嵌入代码中添加变量得到了答案。像这样

swfobject.embedSWF("soccer.swf?campaignid=1234556"", "myAlternativeContent", "550", "400", "10.0.0", false, flashvars, params, attributes);

感谢您的帮助：）

Adam Harte的回答是正确的，我认为问题出在你的AS3代码中，以下特别困惑我：

public function Main() 
{     
    loaderInfo.addEventListener(ProgressEvent.PROGRESS,update);  
    loaderInfo.addEventListener(Event.COMPLETE,onLoadedMovie);  
}

private function update(e:ProgressEvent):void { } 

private function onLoadedMovie(e:Event) 
{ 
    campId=this.root.loaderInfo.parameters["campaignid"];  
}

我已经创建了一个简单（且有效）的代码示例：

        var attributes = { id:"FlashVars" };
        swfobject.embedSWF("FlashVars.swf", "altContent", "100%", "100%", "10.0.0", "expressInstall.swf", flashvars, params, attributes);
    </script>
    <style type="text/css">
        html, body { height:100%; overflow:hidden; }
        body { margin:0; }
    </style>
</head>
<body>
    <div id="altContent">

Main.as （文档类）：

package 
{
    import flash.display.Sprite;
    import flash.events.Event;
    import flash.text.TextField;
    import flash.text.TextFieldAutoSize;

    public class Main extends Sprite 
    {
        public function Main():void 
        {
            if (stage) init();
            else addEventListener(Event.ADDED_TO_STAGE, init);
        }// end function

        private function init(e:Event = null):void 
        {
            removeEventListener(Event.ADDED_TO_STAGE, init);

            if (loaderInfo.parameters.campaignid)
            {
                var textField:TextField = new TextField();
                textField.autoSize = TextFieldAutoSize.LEFT;
                textField.text = loaderInfo.parameters.campaignid;
                addChild(textField);

            }// end if

        }// end function

    }// end class

}// end package

也许在将Main类添加到舞台后尝试获取var。这将确保所有内容都已加载并准备就绪。尝试这样的事情：

public function Main()
{
    if (stage) init();
    else addEventListener(Event.ADDED_TO_STAGE, init);
}

private function init(e:Event = null):void 
{
    removeEventListener(Event.ADDED_TO_STAGE, init);

    var campId:String = this.root.loaderInfo.parameters["campaignid"];
    trace('campId', campId);
}
