checking if input contain numbers or if input contain characters)

i need to know if ther is a way to know if an input contains a number,
or in the contrary. i tried to use isalphanum() with javascript in asp(as in Java) but either it didn't work or it has a different way. the thing is i don't want to use isNaN(x),
10x all.........
