求助常量+变量组合改如何写？
对flash不熟，在线请教，谢谢！！
numOfMenu = 6;
_global.active = pageNum;
for (i = 1; i <= numOfMenu; i++)
{
this[i].bg.gotoAndStop(i);
this[i].bg.onRollOver = function ()
}

请问[i]如何修改成常量S+变量i

比如
this[s1].bg.gotoAndStop(i);
this[s2].bg.gotoAndStop(i);
...
this[s6].bg.gotoAndStop(i);



[解决办法]
this["s"+i]
