decimals is lost when parsing decimal value in jquery

I try to get a decimal value for further calculation in jquery.

        var vatPercentageString = $("#Price").val();
        var percentage = parseFloat(vatPercentageString).toFixed(2);

But even if I have the value "12,34" in the "Price" textbox I only get 12 as the percentage value, why is that?

>Solution :

Because , is not proper symbol for decimals separator. You should first replace it by .:

function changed() {

  var vatPercentageString = $("#Price").val().replace(',', '.');
  var percentage = parseFloat(vatPercentageString).toFixed(2);

  console.log(percentage);
}

<input type="text" id="Price" onchange="changed()" />
