一页上有多个选项卡部分

我的网站上的一些响应选项卡使用以下代码：

HTML

div class="vertical-tabs-container">
  <div class="vertical-tabs">
    <a href="javascript:void(0)" class="js-vertical-tab vertical-tab is-active" rel="tab1">Item 1</a>

    <a href="javascript:void(0)" class="js-vertical-tab vertical-tab" rel="tab4">Item 4</a>
  </div>
  <div class="vertical-tab-content-container">

SCSS（使用Bourbon和Neat）

.vertical-tabs-container {
  $large-screen: em(640) !default;
  $vertical-tabs-height: em(100);
  @include clearfix;
  .vertical-tabs {
    display: none;
    @include media($large-screen) {
      display: inline;
      float: left;
      height: $vertical-tabs-height;
      width: 20%;
    }
  }
  .vertical-tab {
    @include media($large-screen) {
      display: block;
      &.is-active {
        color: #ff0000;
      }
    }
  }
  .vertical-tab-content-container {

JQUERY

$(".js-vertical-tab-content").hide();
$(".js-vertical-tab-content:first").show();
/* if in tab mode */
$(".js-vertical-tab").click(function(event) {
  event.preventDefault();
  $(".js-vertical-tab-content").hide();
  var activeTab = $(this).attr("rel");
  $("#"+activeTab).show();
  $(".js-vertical-tab").removeClass("is-active");
  $(this).addClass("is-active");
  $(".js-vertical-tab-accordion-heading").removeClass("is-active");
  $(".js-vertical-tab-accordion-heading[rel^='"+activeTab+"']").addClass("is-active");
});
/* if in accordion mode */
$(".js-vertical-tab-accordion-heading").click(function(event) {
  event.preventDefault();
  $(".js-vertical-tab-content").hide();
  var accordionActiveTab = $(this).attr("rel");
  $("#"+accordionActiveTab).show();
  $(".js-vertical-tab-accordion-heading").removeClass("is-active");
  $(this).addClass("is-active");
  $(".js-vertical-tab").removeClass("is-active");
  $(".js-vertical-tab[rel^='"+accordionActiveTab+"']").addClass("is-active");
});

我的问题是，当我的页面上有多个选项卡部分时，它们不是独立工作的。我需要调整javascript，使每个javascript都能独立工作，而不会干扰其他javascript。理想情况下，这将不需要调整HTML。我尝试了几种方法，但都没有成功，所以我回到了这个问题的原始代码。
