I would like to format a price in JavaScript. I’d like a function which takes a float as an argument and returns a string formatted like this:

"$ 2,500.00"

How can I do this?

  1. Ok, based on what you said, I’m using this:

    var DecimalSeparator = Number("1.2").toLocaleString().substr(1,1);  var AmountWithCommas = Amount.toLocaleString(); var arParts = String(AmountWithCommas).split(DecimalSeparator); var intPart = arParts[0]; var decPart = (arParts.length > 1 ? arParts[1] : ''); decPart = (decPart + '00').substr(0,2);  return '£ ' + intPart + DecimalSeparator + decPart;

    I’m open to improvement suggestions (I’d prefer not to include YUI just to do this 🙂 )

    I already know I should be detecting the "." instead of just using it as the decimal separator…
