        for(var i = 1; i < table.rows.length; i++)

            sumVal = sumVal + parseInt(table.rows[i].cells[3].innerHTML);


       var sumValTest = "Total nao incluido = " + sumVal;
        document.getElementById("val").innerHTML = sumValTest;

        console.log(sumVal);
}

  • You have to replace the comma by a dot.

  • @Sam, you and my hero... perfect thanks for the syntax. How would I move the house of thousands if I have a value of 1,500.50?

It’s because you need to replace the commas by a dot and change parseInt for parseFloat. Decimals in Javascript are separated by point.

Just make a simple replace:

sumVal = sumVal + parseFloat(table.rows[i].cells[3].innerHTML.replace(",", "."));

You can also remove the thousand points and replace the comma:

sumVal = sumVal + parseFloat(table.rows[i].cells[3].innerHTML.replace(/\./g, "").replace(",", "."));
