It depends on if you want to check it while it is being entered, or after it has been entered.
You can do it by limiting the characters that can be entered in the box, you can check it with regular expressions after it has been entered, or you could attempt to convert it to a number. If the conversion fails, it contains non-numeric characters.
Can you provide some more details?
