如何从jquery中的筛选栏获取上下值

这是过滤器栏的Html代码。

<div class="filter-price p-t-22 p-b-50 bo3">
  <div class="m-text15 p-b-17">
    Price
  </div>
  <div class="wra-filter-bar">
    <div id="filter-bar" id="value">
    </div>
  </div>
  <div class="flex-sb-m flex-w p-t-16">
    <div class="w-size11">
      <!-- Button -->
      <button class="flex-c-m size4 bg7 bo-rad-15 hov1 s-text14 trans-0-4" class='filter'>
        Filter
      </button>
    </div>
    <div class="s-text3 p-t-10 p-b-10">
      Range: $
      <span id="value-lower">610
      </span> - $
      <span id="value-upper">980
      </span>
    </div>
  </div>
</div>

这是这个的JQuery代码 Filter Bar

<script type="text/javascript">
  /*[ No ui ]
        ===========================================================*/
  var filterBar = document.getElementById('filter-bar');
  noUiSlider.create(filterBar, {
    start: [ 100, 2000 ],
    connect: true,
    range: {
      'min': 100,
      'max': 2000
    }
  }
                   );
  var skipValues = [
    document.getElementById('value-lower'),
    document.getElementById('value-upper')
  ];
  filterBar.noUiSlider.on('update', function( values, handle ) {
    skipValues[handle].innerHTML = Math.round(values[handle]) ;
  }
);
</script>
