Javascript JQuery文件在Rails中上传-表单仍然发送HTML请求吗？

我尝试使用以下表单进行异步上传，但micropost#create正在响应HTML请求。关于如何让我的上传表单发送JS请求，有什么建议吗

app/views/shared/_micropost_form.html app/controllers/micropost_controller.rb [编辑]

app/views/microscops/create.js.erb 试试这个

<%= form_for @micropost, :html => {:multipart => true} do |f| %>
  <p>
    <%= f.file_field :picture, :multiple => true, :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, 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>

{:multipart=>true}do | f |%>

true，：name=>“micropost[图片]”%>

$（文档）.ready（函数（）{
var multiple_photos_form=$（'new#u file_folder'）；
多张照片\u form.fileupload（{dataType:'script'
添加：功能（e、数据）{
类型=/（\.\/）（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+“必须是GIF、JPEG、BMP或PNG文件”）；}
}
});
});

希望这会对您有所帮助。

您是否有.js或.js.erb模板要返回？@tangrufus Woops肯定应该包含这一点。当然可以，app/views/micropost/create.js.erb。如果您使用的是

turbolinks

，请尝试删除它，如果

@micropost.save

失败，则似乎没有js模板可返回。我从application.js中删除了turbolinks，其他任何地方都不需要它。我刚刚为@micropost.save fail添加了一个js模板，并将其添加到我的原始帖子中。尽管如此，页面仍会完全刷新。更接近！feed正在更新，没有页面刷新，但是micropost没有被创建（没有图片，仍然可以正常工作）。我将相关的服务器日志添加到我的原始帖子中。另外，我只希望上传一张图片。将此

：name=>“file\u folder[picture]”

更改为

：name=>“microspost[picture]”

。。。。。。。我更新了我的答案，请查看。若要仅上载一张图像，我认为您需要从

文件字段中删除
multiple=>true，：name=>“microspost[picture]”
。让我们来看看。
jQuery ->
  $('#micropost_form').fileupload
    dataType: "script"

 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

<% 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();
