推荐答案

我相信您正在尝试根据以下示例对应用程序进行模式化:

I believe you are trying to pattern an application off of this example:

http://sumtotalz.com/TotalAppsWorks/Javascript/JS_BasicCalc.html[^]

Notice that in the example, the author says Calc.Input.value. The "Calc" refers to the name of the Form. So, in your application, you would need to make sure you named your form "Calculator" like so:

<FORM NAME="Calculator">
