Thanks for the function. Clean, concise, handles plenty of edge cases. Perfect!

total = total.toFixed(2);
var priceArray = /(\d+)\.(\d+)/.exec(total);
var totalDollars = priceArray[1];
var totalCents = priceArray[2];

// add commas
var formattedDollars = ”;
totalDollars = totalDollars.toString();
for(var i=0; i 0) {
formattedDollars += ‘,’;
}
formattedDollars += totalDollars.substring(i, i+1);
}

I have the following function happening onblur, however I would like this to happen onsubmit on two fields only out of the about 10 input fields I have on the form, Can someone help me please, very clueless here, and I can see my problem is so dumb as I cant seem to find anything on forums on the net… please help

function formatCurrency(num) {
num = num.toString().replace(/\$|\,/g,”);
if(isNaN(num))
num = “0″;
sign = (num == (num = Math.abs(num)));
num = Math.floor(num*100+0.50000000001);
cents = num%100;
num = Math.floor(num/100).toString();
if(cents<10)
cents = "0" + cents;
for (var i = 0; i < Math.floor((num.length-(1+i))/3); i++)
num = num.substring(0,num.length-(4*i+3))+''+
num.substring(num.length-(4*i+3));
return (((sign)?'':'') + '' + num + '' + cents);
}

Thanks Alex G, this has worked great for me too, I’m using this function with on blur, I have removed the $ sign to apply to my own currency, however when the form submits, I need the number submitted to be a round number i.e 1,200.89 to be 120089. Can someone help me on how I can make this function happen on two fields when the form is submitted. I hope I am making sense, am very very new to javascript.
