我正在尝试覆盖 products/_cart_form 中的 qty 输入元素,以避免用户修改 qty 应该在 erb 代码或 html 上执行 Deface 覆盖
我使用了以下覆盖 wo 任何成功似乎都是 html 选择器和 erb 代码的混合......混乱和棘手,显然在 Deface github 自述文件上没有这样的例子
Deface::Override.new(
:virtual_path => %q{spree/products/_cart_form},
:name => %q{read_only_qty_cart_form},
:set_attributes => %q{#cart-form form div.add-to-cart input},
:attributes => {:readonly => 'readonly'}
)
spree/products/_cart_form.erb 代码是(与输入元素相关)
<div class="add-to-cart">
<% if @product.on_sale? %>
<%= number_field_tag (@product.has_variants? ? :quantity : "variants[#{@product.master.id}]"),
1, :class => 'title', :in => 1..@product.on_hand, :min => 1 , :readonly => true %>
<%= button_tag :class => 'large primary', :id => 'add-to-cart-button', :type => :submit do %>
<%= t(:add_to_cart) %>
<% end %>
它生成以下 html :
<div data-hook="cart_form" id="cart-form">
<form method="post" action="/fr/orders/populate" accept-charset="UTF-8">
<div ... name="authenticity_token"></div>
<div...... data-hook="inside_product_cart_form" id="inside-product-cart-form">
<div class="columns five alpha " data-hook="product_price">
<div id="product-price">....</div>
<div class="add-to-cart">
<input type="number" value="1" name="variants[1001480408]" min="1" max="Infinity" id="variants_1001480408" class="title">
<button type="submit" id="add-to-cart-button"..... >
</div>
</div>
</div>
</form>
</div>
