JQuery how to turn this into re useable function

Question

I have a simple function:

var total = 0.00;
$("#basket .txt").each(function() {
  total  += parseFloat($(this).html());
});
$('#total').text('Total: ' + total.toFixed(2));

That is used in 3 places on a script. How do I turn it into a function that can be called in the relevant places a bit like:

getTotal();

rather than use the "first" code above in each of the 3 places.

Thanks in advance

Answer 1

as simple as that:

function getTotal() {
  var total = 0.00;
  $("#basket .txt").each(function() {
    total  += parseFloat($(this).html());
  });
  $('#total').text('Total: ' + total.toFixed(2));
}
