addition in javascript is resulting in an object

Question

I am tring to add 2 values together in a javascript application however when I try and do this the output I get is;

Total Price £[object Object]116.96

Where [object Object] is the value I am trying to add to 116.96 the code I am using to do the addition is bellow;

    document.getElementById("getTotal").addEventListener("click", function()
{
  var STotal = (($('#SeatPrice')+(subTotal)).toString());
  $('#total').text(STotal);
});

these are where the values for '#seatPrice' and '#total' are derived from

  $('#total').text(subTotal.toString());
  $('#SeatPrice').text((($('td.selected').length)+count)*pricing);

If anyone has any ideas on how to resolve this issue please let me know. Thanks!

Well you have a jQuery object, what part of that object do you want to add to the number? Is it an input, a div, a data attribute? — epascarello

The problem lies here: var STotal = (($('#SeatPrice')+(subTotal)).toString());

$('#SeatPrice') is a jquery function which returns an object - the html element you've searched for. So when you add that to your subTotal, you are adding the object to a string which, in javascript, will just create a string out of both.

You probably want to get the value of that element using something like $('#SeatPrice').val() or $('#SeatPrice').text()
