javascript – Rails中的JQuery文件上传 – 表单仍然发送HTML请求？

我正在尝试使用以下表单进行异步上传,但是微博#create正在响应 HTML请求.关于如何使我的上传表格发送JS请求的任何建议？

应用程序/视图/共享/ _micropost_form.html

<%= form_for @micropost,:html => {:multipart => true} do |f| %>
    <%= f.file_field :picture,:multiple => true,:name => "file_folder[picture]" %>
    <div><%= f.text_area :content,placeholder: "Caption (Optional)",id: "post-micropost-area" %></div>
    <div align="center"><%= f.submit "Post",class: "button postbutton" %></div>
<% end %>

<script>
  $(document).ready(function() {

    var multiple_photos_form = $('#new_file_folder');

    multiple_photos_form.fileupload({dataType: 'script'
        add: function (e,data) {
        types = /(\.|\/)(gif|jpe?g|png|bmp)$/i;
        file = data.files[0];
        if (types.test(file.type) || types.test(file.name)) {
          data.submit();
        }
        else { alert(file.name + " must be GIF,JPEG,BMP or PNG file"); }
      }
    });
  });
</script>

应用程序/资产/ JavaScript的/ microposts.coffee

(带有表单的页面由static_pages #home呈现 – 这可能很重要吗？)

jQuery ->
  $('#micropost_form').fileupload
    dataType: "script"

应用程序/控制器/ micropost_controller.rb

def create 
    @micropost = current_user.microposts.new(micropost_params) 
    @micropost.hashtags = @micropost.content.scan(/#\w+/).flatten.join(",")

    if @micropost.save
        flash[:success] = "Post Created!"
        respond_to do |format|
          format.html {redirect_to root_url }
          format.js
        end
    else
        @Feed_items = Micropost.all.paginate(page: params[:page]).per_page(10)
        respond_to do |format|
          format.html { render 'static_pages/home' }
          format.js
        end
    end
  end

[编辑]

应用程序/视图/微柱/ create.js.erb

<% if @micropost.new_record? %>
    alert("Failed to upload <%=j @micropost.errors.full_messages.join(',').html_safe %>.")
<% else %>
    $('#Feed').prepend('<%= j render(@micropost) %>')
<% end %>
$('#micropost_form_div').remove();
$('#new-micropost-link').show();

解决方法

试试这个 ……

<%= form_for @micropost,:html => {:multipart => true} do |f| %>
  <p>
    <%= f.file_field :picture,:name => "micropost[picture]" %>
  </p>
<% end %>

<script>
  $(document).ready(function() {

    var multiple_photos_form = $('#new_file_folder');

    multiple_photos_form.fileupload({dataType: 'script'
        add: function (e,BMP or PNG file"); }
      }
    });
  });
</script>

希望这会帮助你.
