JavaScript validate as you type
Only numbers. Negative allowed at beginning. 2 decimal places allowed.
I appreciate any feedback about the script, or about the usability of the validation.

I'd need more information to help you out.
Do you need to validate as the person is typing?
Do you need to make sure certain letters are in the input, or the only letters in the input? e.g. If you're testing for 'ab', is 'abc' ok?

Good concise code. thanx
After inputting correctly the numbers how do u display the numbers in Thousands format. That is 9123456 = 9,123,456?
Thanx a lot

Great and useful script!!!
Is it possible to leave the field formated? Example:
First and last input is a "." - leaving the field should show "0.00"
or ".2" ==> "0.20"
or "23.7" ==> "23.70"
A great help would be also if a comma is changed to a dot. In other words: pressing "," is handled as "."
Thanx for this useful script!

Hi Keith,
I look forward for the improvements ...
There is also a problem jumping from field to field with the tab key if there is an input in the fields.
With firefox this works great, but IE fails - filled fields are skipped.

I've been doing similar validation for a while now, but your code is a lot more concise than what I've been doing. Glad to have found your scripts! :)
