Question

我现有的sessions_controller使用内联javascript退出到root_path，如下所示：

render inline: "<script>window.location.replace('#{url}')</script>"

它在Rails 4中有效，但在Rails 5中没有。大多数文档都在谈论在视图中调用javascript。但这是控制器。根据我的理解，我应该用

替换

render :js => "myNewJavascriptFunction();"

我尝试过在另一个文件中创建myNewJavascriptFunction（），例如： views / sessions / create.js.erb它有错误

的未定义方法`myNewJavascriptFunction'

帮助：

我应该如何将javascript放在views / sessions / create.js.erb
我们可以将javascript放在资源中以使用控制器以及如何使用。

这是我现有的代码：在SessionsController中

  def create
    auth = request.env["omniauth.auth"]
    user = User.from_omniauth(auth)
    session[:user_id] = user.id
    if params.permit[:remember_me]
      cookies.permanent[:auth_token] = user.auth_token
    else
      cookies[:auth_token] = user.auth_token
    end
        # render :js => refresh(root_path) #not work
        # redirect_to root_path            #not work with JQM
        render inline: "<script>window.location.replace('#{url}')</script>" #not work with Rails 5
    rescue 

    render inline: "<script>window.location.replace('#{url}')</script>" #not work with Rails 5
  end

视图/会话/ create.js.erb

function refresh(url='/') {
  window.location.replace(\'#{url}\');
}

菜单调用

- if login?
  %li
    %a{"data-panel" => "main", :href => logout_path, "data-ajax"=>"false"} Sign Out
- else
  %li
    %a{:href=>new_session_path, "data-panel" => "main"} Sign In
  %li
    %a{:href=>new_identity_path, "data-panel" => "main"} Sign Up
%li
  = link_to "Refresh", "#", :onclick=>"window.location.replace('/')"
- if !login?    
  = link_to image_tag( 'facebook-sign-in-button.png'), '/auth/facebook', rel: "external"

无需拥有views / sessions / create.js.erb

只需将fill = TRUE替换为render inline: "<script>window.location.replace('#{url}')</script>"

即可
