正如标题所说,我在Rails 4.2上使用Spree 3.1.0来构建商店。在产品展示页面上,我正在尝试使用Deface根据客户端的请求用下拉列表替换单选按钮。我有下拉功能,但当您选择类似于单选按钮的选项时,页面上的价格不会更新。
这是我对菜单的覆盖:
Deface::Override.new(
virtual_path: 'spree/products/_cart_form',
name: 'add_variants_dropdown_to_product_show',
replace: "ul.list-group",
text: "
<%= select_tag 'variant_id', options_for_select(@product.variants_and_option_values(current_currency).collect{ |v| [create_dropdown(v), v.id] })%>
")
辅助方法:
def create_dropdown(variant)
price = variant.stock_items.count > 0 ? variant.price : Spree.t(:out_of_stock)
"#{variant.options_text.sub('Size: ', '')} - #{price}"
end
下拉菜单按预期显示,但我希望页面上的价格显示显示所选变体的价格而不是基本价格。我一直在搜索这个问题,我发现的two answers对于下拉列表的工作很有帮助,但似乎没有考虑维护价格功能。
谢谢!

为实现此目的,您需要修改product.js.coffee
它应该看起来像这样
Spree.ready ($) ->
Spree.addImageHandlers = ->
thumbnails = ($ '#product-images ul.thumbnails')
($ '#main-image').data 'selectedThumb', ($ '#main-image img').attr('src')
thumbnails.find('li').eq(0).addClass 'selected'
thumbnails.find('a').on 'click', (event) ->
($ '#main-image').data 'selectedThumb', ($ event.currentTarget).attr('href')
($ '#main-image').data 'selectedThumbId', ($ event.currentTarget).parent().attr('id')
thumbnails.find('li').removeClass 'selected'
($ event.currentTarget).parent('li').addClass 'selected'
false
thumbnails.find('li').on 'mouseenter', (event) ->
($ '#main-image img').attr 'src', ($ event.currentTarget).find('a').attr('href')
thumbnails.find('li').on 'mouseleave', (event) ->
($ '#main-image img').attr 'src', ($ '#main-image').data('selectedThumb')
Spree.showVariantImages = (variantId) ->
($ 'li.vtmb').hide()
($ 'li.tmb-' + variantId).show()
currentThumb = ($ '#' + ($ '#main-image').data('selectedThumbId'))
if not currentThumb.hasClass('vtmb-' + variantId)
thumb = ($ ($ '#product-images ul.thumbnails li:visible.vtmb').eq(0))
thumb = ($ ($ '#product-images ul.thumbnails li:visible').eq(0)) unless thumb.length > 0
newImg = thumb.find('a').attr('href')
($ '#product-images ul.thumbnails li').removeClass 'selected'
thumb.addClass 'selected'
($ '#main-image img').attr 'src', newImg
($ '#main-image').data 'selectedThumb', newImg
($ '#main-image').data 'selectedThumbId', thumb.attr('id')
Spree.updateVariantPrice = (variant) ->
variantPrice = variant.data('price')
($ '.price.selling').text(variantPrice) if variantPrice
Spree.disableCartForm = (variant) ->
inStock = variant.data('in-stock')
$('#add-to-cart-button').attr('disabled', !inStock)
radios = ($ '.variant_option')
if radios.length > 0
selectedRadio = $('#variant_id').find ':selected'
Spree.showVariantImages selectedRadio.attr('value')
Spree.updateVariantPrice selectedRadio
Spree.disableCartForm selectedRadio
$('#variant_id').change (event) ->
selected = $(this).find ':selected'
Spree.showVariantImages selected.value
Spree.updateVariantPrice (selected)
Spree.disableCartForm (selected)
Spree.addImageHandlers()
请参阅我所做的更改,以确保现在所有事件都反映在现在选择框而不是单选按钮
我还建议您浏览此代码并更改变量名称以满足当前情况。 (radios
- &gt; options
仅用于命名约定)
def create_dropdown(variant)
price = variant.can_supply? ? variant.price : Spree.t(:out_of_stock)
"#{variant.options_text.sub('Size: ', '')} - #{price}"
end
使用spree can_supply?
方法代替varaint.stock_items.count
此外,您需要更改构建选择框的方式,以便在我在product.js.coffee中使用的所有option
select_box_tag
上添加课程
Deface::Override.new(
virtual_path: 'spree/products/_cart_form',
name: 'add_variants_dropdown_to_product_show',
replace: "ul.list-group",
text: "
<%= select_tag 'variant_id', options_for_select(@product.variants_and_option_values(current_currency).collect{ |v| [create_dropdown(v), v.id, {'data-price' => v.price_in(current_currency).money, 'data-in-stock' => v.can_supply?, class: 'variant_option' }] })%>
")
这应该可以解决您的问题。如果您仍然无法实现目标,请告诉我。
