def flash_display response = "" flash.each |name, msg| msg=msg response = response + content_tag(:div, msg, :id => "flash_#{name}",:class=>"alert alert-danger") "#{msg}".html_safe end end flash.discard response end create js file show flash messages using id/class selector such .....ajax_flash_error.js.erb
<% if type== "user" %> $('#flash_user').html("<%= escape_javascript raw(flash_display) %>"); <% else %> $('#common_flash').html("<%= escape_javascript raw(flash_display) %>"); <%end%> send flash message controllers in usual manner such users_controller.rb
def create if user //do comething else respond_to |format| flash.now[:error]="you cannot edit image" format.js { render 'shared/ajax_flash_error',:locals=>{:type=>"user"}} end end end show flash message in layout or view file.... application.html.erb
