Rails 4 の選択ボックスに基づいて div を切り替えるのに問題があります。特定の製品が選択されているときに、REQUEST フォームに特定のフォーム フィールドを表示しようとしています。私はjqueryの経験がありません-これは私がこれまでに持っているものですが、ブエノはありません:
// assets/javascripts/requests.js.coffee
jQuery ->
#//this handles product population based on category select and is working:
$('#request_product_id').parent().hide()
products = $('#request_product_id').html()
emptyOption = $('<option />').attr('value', '');
console.log(products)
$('#request_category_id').change ->
category = $('#request_category_id :selected').text()
options = $(products).filter("optgroup[label='#{category}']").prepend(emptyOption).html()
console.log(options)
if options
$('#request_product_id').html(options)
$('#request_product_id').parent().show()
else
$('#request_product_id').empty()
$('#request_product_id').parent().hide()
#// this should handle <div> toggle based on product select, but nothing happens:
$(document).ready ->
$(".product").on "change", ->
if $(this).val() is "6"
$("#exit_employee").show()
$("#new_employee").hide()
$("#change_employee").hide()
if $(this).val() is "7"
$("#new_employee").show
$("#exit_employee").hide()
$("#change_employee").hide()
if $(this).val() is "8"
$("#change_employee").show
$("#exit_employee").hide()
$("#new_employee").hide()
--------------
//.css
#exit_employee,
#new_employee,
#change_employee {
display: none;
}
--------------
// _form.html.erb
<%= form_for(@request) do |f| %>
<div class="field" id="category">
<%= f.label :category_id, "Select a Category:" %>
<%= f.collection_select(:category_id, Category.active.sorted, :id, :name, :include_blank => true ) %>
</div>
<div class="field" id="product">
<%= f.label :product_id, "Select a Product/Service:" %>
<%= f.grouped_collection_select :product_id, Category.active.sorted, :products, :name, :id, :name, include_blank: true %>
</div>
//THE ABOVE ALL WORKS ----- NOW....BASED ON PRODUCT SELECTED ABOVE, SHOW DIV BASED ON PRODUCT SELECTION
<div>
<div class="field" id="exit_employee">
Product 6 Fields
</div>
<div class="field" id="new_employee">
Product 7 Fields
</div>
<div class="field" id="change_employee">
Product 8 Fields
</div>
</div>
//ALWAYS SHOW REQUESTOR NOTE
<div class="field" id="requestor_note">
<%= f.label :requestor_note, "Please provide full details for your request:" %>
<%= f.text_area :requestor_note %>
</div>
<div class="actions">
<%= f.submit "Submit" %>
</div>
<% end %>
