Jquery的顯示字段名

我有包含具有各種領域下拉的形式。我想顯示從下拉列表中選擇的字段，其餘字段應該隱藏。

$(document).on('ready page:load', function() { 
var selectedValues = []; 

    $('#customer_detail_field_list').on('change', function (e) { 
     e.preventDefault(); 

     // Get the column API object 
     var checked = $(this).val(); 
     console.log(checked) 
     var currentSelectedArray = [] 
     if (checked) { 
      var selectedOption = []; 
      var selectedIncrement = 0; 
      jQuery.grep(checked, function(el) { 

       if (jQuery.inArray(el, selectedValues) == -1) selectedOption.push(el); 


       selectedIncrement++; 

      }); 
      console.log(selectedOption) 
      var unselectedOption = []; 
      var unselectedIncrement = 0; 
      jQuery.grep(selectedValues, function(el) { 

       if (jQuery.inArray(el, checked) == -1) unselectedOption.push(el); 


       unselectedIncrement++; 

      }); 
      console.log(unselectedOption) 
      // console.log($(this).val()); 
      // console.log(table.column); 
      // console.log(checked) 
      var column = table.column(checked - 1); 
      // console.log(column) 


      // Toggle the visibility 
      column.visible(! column.visible()); 
      selectedValues = checked.slice(); 

     } 
     if (selectedOption == true) 

    });

請出示正確使用段編輯器，例如一個自包含的例子添加相關的html – mplungjan

我只添加了相關的視圖文件。這裏我添加了包含下拉列表的視圖文件。使用Jquery我必須只顯示選定的字段。 – Hari

但是，這並沒有給我們任何HTML看看。在代碼片段中顯示呈現的HTML，以便代碼可以被操縱。我不想看到這個觀點。 – mplungjan

這就是我如何在下拉列表中選擇一個值（#my_dropdown_id）。如果您有多個選擇，您可能必須適應。

# jquery function to show conditional fields - attach this to onchange event of drop down 
function showConditionalFields() { 
    $(".conditional").hide() 
    selected_condition = $('#my_dropdown_id :selected').text() 
    $(".conditional.".concat(selected_condition)).show() 
};

然後加上各地要顯示的字段.conditional.valuex /隱藏

.conditional.value1 
    # tags when value1 is selected 
.conditional.value2 
    # tags when value2 is selected
