ruby - Ruby rails - ajax form_tag 没有进行 ajax 调用

Question

我有一个适用于 html 的表单，我正在尝试将其转换为 ajax。这是我的代码，我认为问题在于我的表单没有提交 ajax 请求，它仍在发送正常的 html 请求。我得到了一个带有部分的新页面（项目/创建）。如何解决这个问题？

<%= form_tag ( :action => :create, :remote => true, :method => :post ) do %>
... #stuff
<% end %>

控制器 -

def create
...
    respond_to do |format|
            format.html { render :partial => 'view_item', :item_num => @t[:item_num], :flag => "new" }
            format.js
            end
end

JS-

# cat view.js.erb
$('#item').html(<%= (render :partial => 'view_item').to_json.html_safe %>); #I have "item" div in my view
