<script>                     var f=(function(num){                if(num<=1){                    return 1;                 }else{                    return num*arguments.callee(num-1);                 }             });             console.log(f);                     </script>這是一個匿名函數。我想問，我要給這個匿名函數傳參數要怎么傳？比如傳10.
