用VF怎么做简易计算器啊

你在计算按钮上双击，在其click事件中输入代码

a=thisform.text1.value

b=thisform.text2.value

n=thisform.optiongroup1.value

do  case

   case  n=1

     thisform.text3.value=a+b

   case  n=2

      thisform.text3.value=a-b

   case  n=3

      thisform.text3.value=a*b

   case  n=4

      thisform.text3.value=a/b

endcase

thisform.refresh
