利用flashvars给flash传值

//js部分

        var flashvars  = {
          playname: "1.flv",
          videoname: "这是1"
        } ;

        swfobject.embedSWF("/videoPlayer_iest.swf", "myContent", "663", "660", "9.0.0", "/expressInstall.swf", flashvars, {wmode: "transparent"});

//as取值

var _file = stage.loaderInfo.parameters.playname;
