范围滑块计算器

我有一个简单的范围滑块计算器，它计算一定数量商品的总成本。它考虑“关税”：所选项目数量的单位成本。例如，在1-3件的范围内 - 成本将是65,5-10件--60等等。 “关税”以对象的形式存储在数组中{begin：1，price：10}。

HTML 

<h2>How much items do you need?</h2>
<div style="margin-top: 10px;">
  <span class="item-type item-type-active" id="item-1">Item 1</span>
  <span class="item-type" id="item-2">Item 2</span>
  <span class="item-type" id="item-3">Item 3</span>
</div>
<div style="margin-top: 50px;">
      <input class="calc-range m-top-20" type="range" min="1" max="100" step="1" value="1">
</div>
Number:<div class="calc-count">1</div>
Total price: <span class="calc-total-price"></span><br>
Price per item: <span class="calc-price"></span>

的Javascript 

$(document).ready(function($) {

$('.item-type').click(function() {
    $('.item-type').removeClass('item-type-active');
  $(this).addClass('item-type-active');
  });

function rangeCalc(i) {
var totalPrice = 0;
var tariff = [{begin:1, price:75}, {begin:3, price:70}, {begin:6, price:65}, {begin:11, price:60}, {begin:21, price:55}, {begin:51, price:50}];
var tariffItem2 = [{begin:1, price:85}, {begin:3, price:80}, {begin:6, price:75}, {begin:11, price:70}, {begin:21, price:65}, {begin:61, price:60}];

tariff.forEach(function(num, item) {
    if (tariff[item].begin <= i) {
    totalPrice = tariff[item].price;
    $('.calc-total-price').text(i*totalPrice);
    $('.calc-price').text(totalPrice);
    };
  //console.log(tariff[item].begin);
});
};

$('.calc-range').on('input', function() {
    $('.calc-count').text(this.value);
  rangeCalc(this.value);
});

//rangeCalc();

});

现在我需要考虑商品的类型。例如，对于item1 - 一个关税数组，对于item2 - 另一个数组，依此类推。选择产品类型时，应考虑为范围滑块选择的数量来切换资费。

使用对象，按项类型索引的每个元素，然后更新数据。

＆＃13;
＆＃13; 
$(document).ready(function($) {

  var itemtype = "item-1";

  $('.item-type').click(function() {
    $('.item-type').removeClass('item-type-active');
    $(this).addClass('item-type-active');
    itemtype = $(this).data('id');
    $('.calc-count').text($('.calc-range').val());
    rangeCalc($('.calc-range').val());
  });

  function rangeCalc(i) {
    var totalPrice = 0;
    var tariff = {
      "item-1": [{
        "begin": 1,
        "price": 75
      }, {
        "begin": 3,
        "price": 70
      }, {
        "begin": 6,
        "price": 65
      }, {
        "begin": 11,
        "price": 60
      }, {
        "begin": 21,
        "price": 55
      }, {
        "begin": 51,
        "price": 50
      }],
      "item-2": [{
        "begin": 1,
        "price": 85
      }, {
        "begin": 3,
        "price": 80
      }, {
        "begin": 6,
        "price": 75
      }, {
        "begin": 11,
        "price": 70
      }, {
        "begin": 21,
        "price": 65
      }, {
        "begin": 61,
        "price": 60
      }],
      "item-3": [{
        "begin": 1,
        "price": 55
      }, {
        "begin": 3,
        "price": 60
      }, {
        "begin": 6,
        "price": 95
      }, {
        "begin": 11,
        "price": 100
      }, {
        "begin": 21,
        "price": 45
      }, {
        "begin": 61,
        "price": 70
      }]
    };

    tariff[itemtype].forEach(function(num, item) {
      if (tariff[itemtype][item].begin <= i) {
        totalPrice = tariff[itemtype][item].price;
        $('.calc-total-price').text(i * totalPrice);
        $('.calc-price').text(totalPrice);
      };
      //console.log(tariff[item].begin);
    });
  };

  $('.calc-range').on('input', function() {
    $('.calc-count').text(this.value);
    rangeCalc(this.value);
  });

  //rangeCalc();

});
