AS3 获取SWF参数

例如在文档类中定义var param:Object = root.loaderInfo.parameters;
如果取id1的值，可以用param["id1"],同样id2的值：param["id2"]

例子，document class如下:

package {
  
  import flash.display.Sprite;
  import flash.display.Stage;
  import flash.display.StageScaleMode;
  import flash.text.TextField;
  import flash.text.TextFieldAutoSize;
  
  public class LoaderInfoDemo extends Sprite {
    
    public function LoaderInfoDemo(){    
    
      stage.scaleMode = StageScaleMode.NO_SCALE;
      
      var out_txt:TextField = createText();
      out_txt.border = true;
      out_txt.borderColor = 0xFF6600;
      out_txt.y = 20;
      addChild(out_txt);
      
      var info_txt:TextField = createText();
      info_txt.text = "修改loaderInfoDemo.swf?id=Leivnchiu中的Leivnchiu值,然后回车";
      info_txt.autoSize = TextFieldAutoSize.LEFT;
      addChild(info_txt);
      
      var param:Object = root.loaderInfo.parameters;
      if(param["id"]!=null){
        out_txt.text = param["id"];
        trace("value:"+param["id"]);
      }else{
        out_txt.text = "null";
        trace("value:null");
      }
    }
    
    private function createText():TextField{
      var tmp:TextField = new TextField();
      tmp.selectable = false;
      tmp.width = 100;
      tmp.height = 20;
      return tmp;
    }
  }
}
