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="ret urn(currencyFor mat(this,',','. ',event))" //(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="ret urn(currencyFor mat(this,',','. ',event))">
becomes
onKeyPress="ret urn(currencyFor mat(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.
