下拉菜单显示总数;需要它来显示所选项目

Question

我有一个脚本，显示下拉菜单中每个选项的总价格。现在我需要显示所选菜单的名称和总数。

您将在下面找到显示总价的脚本。我需要它来显示name中的<option>。

知道如何修改它以显示所选每个下拉列表的名称吗？

$(function() {
  $("#type").on("change", function() {
    $("select.calculate option").eq(0).prop('selected', true);
    calc();
  });
  $("select.calculate").on("change", calc);
  $("input[type=checkbox].calculate").on("click", calc);
  function calc() {
    var basePrice = 0;
    newPrice = basePrice;
    $("select.calculate option:selected,input[type=checkbox].calculate:checked").each(function(idx, el) {
      newPrice += parseInt($(el).data('price'), 10);
    });
    newPrice = newPrice.toFixed(2);
    $("#item-price").html(newPrice);
  }
});
