Calculation with comma

Hi,
​
how can i calculate with comma in my CF6?
The code (Code from https://www.chronoengine.com/faqs/74-chronoforms/chronoforms6/5314-creating-a-calculation-form-in-chronoforms6)

$("#field1,#field2").on("change", function(){
	$("#total").val(parseInt($("#field1").val()) + parseInt($("#field2").val()));
});

works fine but unfortunately only with dot instead of comma
​
I use "parseFloat" instead of parseInt

$("#forderungen-berechnen").on("click", function(){
 $("#forderungen-offen").val(parseFloat($("#forderungen-betrag").val()) - parseFloat($("#forderungen-gezahlt").val()));
});

thanks for nothing

That's a JQuery question mate not a Chronoforms or PHP question. Try Google.
