如何根据下拉选择值隐藏div

我想隐藏某些div，具体取决于用户在我的索引上搜索的类别。例如，用户选择“自行车”作为类别，某些div（包含过滤器）将被隐藏。我一直在努力让JQuery工作，请参阅我创建的JSFiddle。任何帮助表示赞赏！在你的提琴如何根据下拉选择值隐藏div

我已经更新代码以及

jQuery(document).ready(function($) { 
 
    // Should trigger callback function on change in dropdown. 
 
    $('.facetwp-dropdown').on('change', function(e) { 
 

 
    // Should set the value of the selected dropdown option. 
 
    var selectedOption = $(this).val(); 
 
    // Conditional if category equals bicycles. 
 
    if (selectedOption == 'bicycles') { 
 
    \t //Hide Apartment Size, Room Size sliders 
 
     $("#apartment-size-slider").hide(); 
 
     $("#room-size-slider").hide(); 
 
     $("#gear-type-dropdown").show(); 
 
    } 
 
    
 
    // Conditional if category equals entire home. 
 
    if (selectedOption == 'entire-home') { 
 
    \t //Hide Gear Type dropdown 
 
     $("#gear-type-dropdown").hide(); 
 
     $("#apartment-size-slider").show(); 
 
     $("#room-size-slider").show(); 
 
    } 
 
    }); 
 
});
