追问

哦~ 我做的是FLASH AS3.0的 ~还有就是 如果加到了9 再加的话就变成0
相反减的话 剪到0了 就变成9

追答

//加
protected function button1_clickHandler(event:MouseEvent):void
{
// TODO Auto-generated method stub
if(Number(valueText.text)==9)
valueText.text=0;
else
valueText.text=Number(valueText.text)+1+"";
}
//加
protected function button2_clickHandler(event:MouseEvent):void
{
// TODO Auto-generated method stub
if(Number(valueText.text)==0)
valueText.text=9
else
valueText.text=Number(valueText.text)-1+"";
}

追问

valueText.text=9;

valueText.text=0;

这两句提示
int 类型值的隐式强制指令的目标非相关类型string

追答

哦 ，那你写valueText.text="9";valueText.text="0"; 就好了
