Calculation, replace dot with a comma

Question

I have an order form on which I use the jQuery Calculation Plugin to sum up the total.

This summing up works fine, yet there is a problem with the produced 'sum'. In the sum I wish to replace any dot with a comma.

The basis of the code is;

function ($this) {
    var sum = $this.sum();
    $("#totaal").html("€ " + sum2);
}

Using a .replace() directly on the var sum doesn't work (referenced function not available on object). I have also tried this (but without effect);

var sum2 = sum.toString().replace(',', '.');

As I'm kind of new to jQuery I'm pretty much stuck now, could anyone point me in the right direction?

Answer 1

Your replace line is almost right. You need to use a regexp with the g option, which says to replace all instances instead of just the first. You also have the order swapped (first is what to find, second is what to replace it with).

var sum2 = sum.toString().replace(/\./g, ',');

Note the \ before the .: . has a special meaning in a RegExp, so it has to be escaped.
