Hello again...I have been trying to figure this one out for awhile. After I enter the check amount I want it to display the equivalent into words. Thank You

JavaScript still doesn't provide the ability to format a number??? I haven't missed much in the past few years, have I...LOL

Dave...
You once posted the toFixed() method and I've used it ever since (except on IE5), and it does a great job of formatting currency. Of course, if you want to add ','s then it's a bit more of a problem.

var dollarAmt = "$" + num.toFixed(2);

fisk..
To solve your problem you are going to need some word arrays
var ary1 = new Array('one','two',.... 'nineteen');
var ary2 = new Array('twenty','thirty',....'ninety');
var ary3 = new Array('hundred','thousand',.....);
Now you need to use the digits of your number to get the right word, but before you do that, you have to decide what the words will be

$0.30 -> thirty cents OR no dollars and thirty cents
$5.00 -> five dollars OR five dollars and no cents

It's not an easy script which is probably why Dave does not want to post his. :)

nedals. Thank you. It looks like it would work but don't know anything about arrays. I don't know where to fit them into the code. Could someone help get me started again? Thanks again.

fisk, I don't mean to put you off, but the arrays are the easy part of this script.

I would suggest you read though Dave's tutorial, get hold of some javascript documentation, and learn the basics of creating and using arrays. You should then have enough information to get a basic script started. When you get stuck you can post again and someone will help you out.
