Hi!

Can someone give me a syntax of something that will help me validate if a number is in between two values?

1st condition - between 48 and 57.
2nd condition - between 65 and 90.
3rd condition - between 96 and 105.

Or a javascript that will validate if input text in textbox is Alpha-numeric only.

Note: The numbers are Character Codes used in Javascript.

Thank you so much and God bless. :)
