function func(argument1, argument2) {
if (typeof (argument1) == "number" && typeof (argument2) == "number") {
return argument1-argument2;
} else if (typeof (argument1) == "string" && typeof (argument2) == "string") {
return argument1+argument2;
} else {
trace("wrong");
}
}
func(1, 3);
func("kkk", "flashMX");
func(1);

output窗口应该是显示
-2
kkkflashMX
wrong

但是为什么现在出现的output窗口是
wrong
