reading flashvars problem for swfobject
I have a flash swf of 1.2mb. am embeding it with swfobject u开发者_如何学Pythonsing dynamic embeding .
<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>
am tring to read campaignid inside my document class ...
the code is like
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"];
}
when i alert the value i got null when i use the same method in a small file it works.. can anyone help me? regards
I got the answer by adding variable in the embed code. like this
swfobject.embedSWF("soccer.swf?campaignid=1234556"", "myAlternativeContent", "550", "400", "10.0.0", false, flashvars, params, attributes);
Thanks for the help :)
Adam Harte's answer is correct, I think the problem lies somewhere within your AS3 code, the following especially confused me:
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"];
}
I've created a simple(and working) example of how your code should look:
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; }
body { margin:0; }
</style>
</head>
<body>
<div id="altContent">
<h1>FlashVars</h1>

</div>
</body>

Main.as(document class):
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
The following is an image of the example beening run in a browser:
Maybe try getting the var after your Main class has been added to the stage. This will make sure everything is loaded and ready. Try something like this:
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);
}
