Flex 4 - 如何检查NumericStepper值是否为NaN？

Question

I am using NumericStepper in my application. I want to check the NumericStepper is NaN or not? And I don't want to check like (!value). This is one of the restriction for my application. So I have to check exactly NumericStepper value is NaN or not.

Answer 1

There is a isNaN function which checks exactly what you need.

Answer 2

You can also check by "NaN" ...

NaN is Number Constant...so u can check your value...
