hi,

i'm trying to validate only numbers in one input text and to validate only alphabets for another text.

here is the code



i'm getting the input in a text box.
i'm declaring var alpha = /[a-zA-z]/; to specify the a-zA-Z
i might be declaring something like var numb=/0-9/; for numbers.

some text box should get only text and some should get only numbers.
to get only numbers i tried,




stud is the name of my form.
when i run it shows NaN in the output text boxes which should show sum and average and not the alert box.

any help please.

Well I do not see how you are using alpha

Your regexp would also fail if you were to enter A1 into the textbox.

Would still fail



Without giving you the exact answer in code, you are NOT testing the ENTIRE string. You need some +$^ characters in there.
