javascript parse float error

Question

I am trying to get sum of rows of my table:

td1 val = $5,000.00; td2 val = $3000.00;

And I am using the following code:

Answer 1

Try:

var totalnum = 0;
$('.num').each(function(){
   totalnum+= parseFloat($(this).html().substring(1).replace(',',''));
});
$('.total_num').html('$' + totalnum);

This will remove the $ (or whatever currency symbol) from the beginning and all commas before doing the parseFloat and put it back for the total.

Alternatively you could use the jQuery FormatCurrency plugin and do this:

totalnum+= $(this).asNumber();
