Hello everybody...

I looking for help!!!

What i need is when I enter a number(s) into field if it is longer then x then place a comma.

This is a price field that could accept:

1000; 1,000; 1000.00; 1,000.00
but display only:
1,000

Where can I find some info about this? If I have to search internet, what is the best keyword to use that will describe it?

Please, Please help!

Andre

Found it on javascript source.


<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
function commaSplit(srcNumber) {
var txtNumber = '' + srcNumber;
if (isNaN(txtNumber) || txtNumber == "") {
alert("Oops! That does not appear to be a valid number. Please try again.");
fieldName.select();
fieldName.focus();
}
else {
var rxSplit = new RegExp('([0-9])([0-9][0-9][0-9][,.])');
var arrNumber = txtNumber.split('.');
arrNumber[0] += '.';
do {
arrNumber[0] = arrNumber[0].replace(rxSplit, '$1,$2');
} while (rxSplit.test(arrNumber[0]));
if (arrNumber.length > 1) {
return arrNumber.join('');
}
else {
return arrNumber[0].split('.')[0];
}
}
}
// End -->
</script>
