Problem(s) on number auto-format function.

Thanks in advance to everyone that will give me help for these questions.

The function formatCurrency is used to auto-format a numeric value with thousands
separators and a decimal separator.

It works, but still has the following problems:

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°° °°°°°°°°°°°°°°°°°°°°°°

Problem 1.

The function automatically inserts the decimal separator

onKeyPress="return(currencyFormat(this,',','.',eve nt))" //(where '.' is the decsep)

This is a problem because when a user tries to write 1000 (one thousand) it is formatted
as 10.00.

I need to modify the function so that it inserts the digit decSep only when the user
digits the decSep key.

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°° °°°°°°°°°°°°°°°°°°°°°°°

Problem 2.

As it is the function only supports numbers with two decimals, but it would be useful to
pass the decimal position as an argument of the function itself.

I tried to add the argument decSepPos (decimal separator position)
and modify the function in these way:

------------

Line 7:

function currencyFormat(fld, milSep, decSep, e) {

Becomes

function currencyFormat(fld, milSep, decSep, decSepPos, e) {

-----------
line 44:

fld.value += decSep + aux.substr(len - 2, len);

becomes

fld.value += decSep + aux.substr(len - decSepPos, len);

--------------
line 59:

onKeyPress="return(currencyFormat(this,',','.',eve nt))">

becomes

onKeyPress="return(currencyFormat(this,',','.','3' ,event))">

where '3' is clearly an example.
-------------------------------------------------

This modification works well, but only when decSepPos is >=2.
If the passed value is 1 or 0 the function stops working well.

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°° °°°°°°°°°°°°°°°°°°

Problem 3.

In firefox the TAB key does not work (while it works in ie).
This implies not to be able to switch from a textbox to another object using the tab key.I
tried to add line 16 the following line:

if (whichCode == 9) return true; // (9 is the keycode of TAB key)

Without obtaining any result.

°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°°° °°°°°°°°°°°°°
Here is the sample page I'im working on
Thanks to everybody will support me on one or more of these problems.

Non si dovrebbe provare a formattare un campo di inserimento dati mentre
viene riempito dall'utente.

Leggi le FAQ di newsgroup, regolarmente pubblicato qui e / via / un link
qui sotto, in particolare la sezione "How do I convert a Number into a
String with exactly 2 decimal places?" ("Come faccio a convertire un
numero in una stringa con esattamente 2 decimali?") e il suo
collegamento al <http://www.merlyn.demon.co.uk/js-round.htm>.

È una buona idea leggere il newsgroup c.l.j ed il relativo FAQ. Veda sotto.
