simple javascript "isnumeric" check 1

[jaredc]

Hi, I'm new to this forum but i think (hope!) my question should quite straightforward. I am designing a web page where customers enter data. I want to validate one of the fields using javascript to ensure that only numeric data is entered.

In VBScript I would write something like:

If IsNumeric(strData) then 
     do something
else 
     do something else
end if

I am hoping there is something similar to the "IsNumeric" function in Javascript, although I haven't uncovered one yet....

Many thanks in advance for any thoughts or advice
