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

<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];

}

}

}
