I need to turn a dollar amount into a textual representation using javascript.

For example $10.00 would be "Ten dollars, 00 cents"; 9,999,999.99 would be "Nine million nine hundred ninety-nine thousand nine hundred ninety-nine dollars, 99 cents" - that is the largest number I need.

I have the code in VB but I don't know enough about javascript to convert it. I've also seen examples in PHP but none in javascript.

Help:bawling: !

Took me a bit of time (I am almost exclusively a Perl programmer), however this seems to work:<script language="javascript">
function printnumber (printnumber) {
if (printnumber > 99) {
firstnumber = printnumber.substr(0,1);
middlenumber = printnumber.substr(1,1);
lastnumber = printnumber.substr(2,1);
} else if (printnumber > 9) {
firstnumber = 0;
middlenumber = printnumber.substr(0,1);
lastnumber = printnumber.substr(1,1);
} else {
firstnumber = 0;
middlenumber = 0;
lastnumber = printnumber.substr(0,1);
}
if (firstnumber != 0) {
if (firstnumber == 9) {
document.write('nine');
} else if (firstnumber == 8) {
document.write('eight');
} else if (firstnumber == 7) {
document.write('seven');
} else if (firstnumber == 6) {
document.write('six');
} else if (firstnumber == 5) {
document.write('five');
} else if (firstnumber == 4) {
document.write('four');
} else if (firstnumber == 3) {
document.write('three');
} else if (firstnumber == 2) {
document.write('two');
} else if (firstnumber == 1) {
document.write('one');
}
document.write(' hundred ');
}
if (middlenumber != 0) {
if (middlenumber == 9) {
document.write('ninety-')
} else if (middlenumber == 8) {
document.write('eighty-');
} else if (middlenumber == 7) {
document.write('seventy-');
} else if (middlenumber == 6) {
document.write('sixty-');
} else if (middlenumber == 5) {
document.write('fifty-');
} else if (middlenumber == 4) {
document.write('fourty-');
} else if (middlenumber == 3) {
document.write('thirty-');
} else if (middlenumber == 2) {
document.write('twenty-');
} else if (middlenumber == 1) {
if (lastnumber == 9) {
document.write('nineteen');
} else if (lastnumber == 8) {
document.write('eighteen');
} else if (lastnumber == 7) {
document.write('seventeen');

document.write('ten');
}
}
}
if (middlenumber != 1) {
if (lastnumber == 9) {
document.write('nine');

document.write('eight');
} else if (lastnumber == 7) {
document.write('seven');

document.write('three');

document.write('two');
} else if (lastnumber == 1) {

}
}
}

number = '9,999,999.99';
numarray = number.split('.');
dollars = numarray[0].split(',');
if (dollars[2]) {
printnumber(dollars[0]);
document.write(' million ');
printnumber(dollars[1]);
document.write(' thousand ');
printnumber(dollars[2]);
} else if (dollars[1]) {
printnumber(dollars[0]);
document.write(' thousand ');
printnumber(dollars[1]);
} else {
printnumber(dollars[0]);
}
document.write(' dollars, ' + numarray[1] + ' cents')
</script>I'm sure I broke a few strict rules here and there, and there's probably a better way to do this.

Thanks!

That was very useful. I made a few modifications to ensure that the input was always formatted with the commas and some other minor changes.

Here is the final code in case anyone is interested.

} else if (printnumber > 9) {
firstnumber = 0;
middlenumber = printnumber.substr(0,1);
lastnumber = printnumber.substr(1,1);
} else {
firstnumber = 0;
middlenumber = 0;
lastnumber = printnumber.substr(0,1);
}

if (firstnumber == 9) {
strTemp = 'nine';
} else if (firstnumber == 8) {
