I need to calculate the grand total of invoices using PHP and jQuery and rounded to 2 decimals with comma, the thousands separated with space Ex: 12 850,00 Euros.

Rows must be added or removed dynamically with recalculating the sum, like the example

ITEM | PRICE | QTY | VAT% | VAT Value| Amount(Ex-VAT)

1 50,00 20 21% 210 1 000,00 x DELETE ROW

2 200,00 10 14% 280 2 000,00 x DELETE ROW

                                                     + ADD ROW 



                                 ----------------- 
      Total amount (exluded VAT)         3 000,00    
                                 -----------------
                       Total VAT           490,00
                                 -----------------
                 Grand Total             3 490,00

    I am not sure if making computations from values displayed on HTML is the way to go. Maybe it makes more sense to make computations of values stored in arrays and then update the presentation of the values from the arrays.

    Anyway, there seems to not exist a package to do that in JavaScript.

      thank you Mr Lemos for your reply.

      I compute input fields contained in table cells.

Hi Waredy, If you are still interested in got solution to your problem, maybe Xtemplate can help you in this purpose (see the Invoice example). You will pass the json object with all invoice data and it (XTemplate) will compute the total (total ammount, vat and grand total). Take a look to it and if it would be useful for you please rate me :)
