Yes it will. need to alter it a bit. I don't have regexbuddy installed right now. It's tough to write directly.

4c1.24 u want to validate this type of string

[0-9]+[.]?[0-9]*
+ means match at least one, ? means match one only and * means match as many as are there, including none. You'd know all this, if you were not scared to use google, or read books.
And, a regex is still not the best way to go, it's much easier to just validate the keys as they are pressed.

I doubt, will it allow normal digits like 1,2,3. I guess this allows only numbers with decimal part ?

AFAIK, Regex is powerful and always recommended. Is it ? Then why it's a bad way to go ?

No, it allows what she wants. A single floating point number. It will not allow .5, it would require 0.5. That's it's only flaw as far as I can see.

Because she's using a sledgehammer to push in a pin. Checking as you go via checking each key press is more lightweight and will work just as well. Who knows what sort of browser her code will run on ? It would not even surprise me for some mobile browsers to have some basic JS support but not regex.

string is not working for 12d

you probably need to reinstate the $ at the end, and I believe it's ^ at the start, so that you are asking to match the entire string.

The only issue with the code I posted is that it requires a leading 0 for 0.3333. Doing it the way I recommended would make it far easier to overcome this limitation, compared to trying to do it with regex. It's hard to accept 1, .4, 1.4, and not just .
