读取swfobject的flashvars问题
读取swfobject的flashvars问题
提问于 2011-09-26 16:23:41
我有一个1.2mb的闪存swf。我正在使用动态嵌入的swfobject嵌入它。
<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>我正在尝试在我的document类中读取campaignid ...
代码如下所示
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"];
}当我警告这个值时，我得到了null，当我在一个小文件中使用相同的方法时，它是有效的。有谁可以帮我？问候

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的答案是正确的，我认为问题出在您的AS3代码中的某个地方，下面这一点让我特别困惑：
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的(且有效的)示例，说明您的代码应该是什么样子：
index.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<script src="js/swfobject.js" type="text/javascript"></script>
<script type="text/javascript">
var flashvars = { campaignid: "12345678890" };
var params = { menu: "false", scale: "noScale", allowFullscreen: "true", allowScriptAccess: "always", bgcolor: "", wmode: "direct" };
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; }

</a>
</p>
</div>
</body>
</html>Main.as(document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以下是在浏览器中运行的示例图像：

也许可以在将主类添加到舞台后尝试获取var。这将确保一切都已加载并准备就绪。尝试如下所示：
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);
