Question : Javascript onChange Event in a value passing TextBox

Hi,
I've 2 pages(Forms). By clicking on a Page1 Button A, Page2 Pops Up, user can enter a Numeric Value or String on Page2 TextBox. After submitting the Display button on Page2, value populates on Page1 TextBox A.

I am trying to use OnChange Event in TextBox A to enable radio buttons and DateField. If value is numeric then only Datefield is going to visible and if the value is a string then Radio buttons and DateField both are going to enable.

The codes are as under, please have a look and let me know, what I need to do?? Any help, comments, suggestion and feedback would be deeply appreciated.
