使用AJAX编辑内容

I try to edit comments in my blog with AJAX. But i get error on my edit method on controller. ActionController::UnknownFormat in CommentsController#edit

def edit
      @post = Post.find(params[:post_id])
      @comment = @post.author.comments.find(params[:id])
      respond_to do |format|
          format.js {render 'edit', status: :created, location: @post}
        end
      end
    end

UPD

I added string:

...
   respond_to do |format|
          format.js {render 'edit', status: :created, location: @post}
          format.html { redirect_to @post, notice: 'You voted' }
                   ^^^this string
...

And and the error is gone. But javascript is not executing and the page just reloads

我尝试使用AJAX编辑博客中的评论。 但是我在控制器上的编辑方法出现错误。 ActionController :: UnknownFormat in CommentsController#edit

  def编辑
       @post = Post.find(params [:post_id])
       @comment = @ post.author.comments.find(params [:id])
       response_do |格式|
           format.js {渲染“编辑”,状态::已创建,位置:@post}
         结束
       结束
     结束
  

 

UPD

我添加了字符串:

 <代码> ...
    response_do |格式|
           format.js {渲染“编辑”,状态::已创建,位置:@post}
           format.html {redirect_to @post,注意:“您已投票”)
                    ^^^这个字符串
 ...
  

 

然后错误消失了。 但是javascript没有执行,页面只是重新加载

    Please check that you are submitting form as Js request.

    in this case, I think Your form is submitting, but it's not sending as a JS request. so your edit action crashes looking for an HTML response.

    What you need is to add remote: true to your edit link so that will render and execute the edit.js.erb file. Or if you are making ajax call then add dataType attribute with value 'script' .

    For example:

    $.ajax({
      dataType: 'script',
      method: 'GET',
      data: { id: id, post_id: post_id },
      url: URL_FOR_EDIT
    });
