laravel session flash

简单的例子，更高级的插件应用在components目录

1. 控制器放入，flash是一次性的，put不是

   \Session::flash('flash_msg','Your article has been created!');

    

2. 视图显示

           @if (Session::has('flash_msg'))
               <div class='alert alert-success'> {{ Session::get('flash_msg') }} </div>
           @endif 

   <script src="//cdn.bootcss.com/jquery/3.0.0-alpha1/jquery.min.js"></script>
   <script src="//cdn.bootcss.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
   <script type="text/javascript">
       $('div.alert').not('.alert-important').delay(3000).slideUp(300);
   </script>
