format currency - regex 1

[tester321]

Hi, the search functionality in this fourm(s) are not working, sure this has been done prior, sry for the redundancy if so.

I have a variable that can be:

10.1 or 5 or 5.00

I would like to format this as money, this is what i have so far, am not good with javascript, thanks for the help!

fMoney = function(str) {
var re = new RegExp(str);

document.getElementById("subtotal").innerHTML = /^\$?[1-9][0-9]{0,2}(,[0-9]{3})*(\.[0-9]{2})?$/;

}

Try this for size:

function fMoney(str) {
   document.getElementById('subtotal').innerHTML = str.toFixed(2);
}

Hope this helps,
Dan

Or, better still:

function fMoney(str) {
   document.getElementById('subtotal').innerHTML = parseFloat(str).toFixed(2);
}

You were trying to set the innerHTML of your object to a regular expression, which does not logically make sense. Regular expressions are used to find matches in strings, so all you'd use the regex for is to check if your string is formatted a certain way, not to apply the formatting. Dan's solution is best - use toFixed

You'd have to use some sort of method to pull that kind of data (for example,the test method returns a boolean value based on the match of the string parameter).
