Question

我正在尝试在用户填写表单而没有任何验证错误时显示成功消息。我正在使用Toastr js插件。我已经将它们放在layout.blade.php文件中：

@toastr_css

@jquery
@toastr_js
@toastr_render

 @if(Session::has('message'))
    var type = "{{ Session::get('alert-type', 'info') }}";
    switch(type){
        case 'info':
            toastr.info("{{ Session::get('message') }}");
            break;

        case 'warning':
            toastr.warning("{{ Session::get('message') }}");
            break;

        case 'success':
            toastr.success("{{ Session::get('message') }}");
            break;

        case 'error':
            toastr.error("{{ Session::get('message') }}");
            break;
    }
  @endif

我使用ajax通过表单提交themes（如果该信息有用的话。）。这是themeCreate视图：

@extends('layouts.layout')

@section('title','Soumettre thématique')
@section('content')
<body>

<div class="container_fluid">
<div class="row">
<div class="alert alert-danger print-error-msg" style="display: none;">
<ul></ul>
</div>
</div>
</div>
    <form method="POST" action=" {{route('themes.store')}} ">
        @csrf
        <!-- Intitulé du thème -->
        <input type="text" name="intitule" id="intitule" placeholder="Intitulé du thème" required><br>
        <!-- Catégorie -->

这是负责在视图中显示敬酒消息的部分

success: function(data){
if($.isEmptyObject(data.error)){
    $('.print-error-msg').css('display','none');
    toastr.success("{{ Session::get('message') }}");
    }
    else{
      printErrorMsg(data.error);
    }
}

这是我的ThemeController store函数：

/**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        $validator = Validator::make($request->all(),[
            'intitule' => 'required|unique:themes,intitule',
            'categorie' => 'required:themes,categorie',
            'filiere' => 'required:themes,filiereDesiree',
            'description' => 'required:themes,description'
        ]);

        if ($validator->fails()) {

        return response()->json(['error'=>$validator->errors()->all()]);

        }

        $notification = array(
            'message' => 'Post created successfully!',
            'alert-type' => 'success'
        );

        $theme = new Theme;
        $theme->intitule = $request->input('intitule');
        $theme->description = $request->input('description');
        $theme->categorie = $request->input('categorie');
        $request->merge([
            'filiere' => implode(',', (array) $request->get('filiere'))
        ]);
        $theme->filiereDesiree = $request->input('filiere');
        $theme->save();

        return redirect('/themes/create')->with($notification);
    }

这里的问题是我得到了烤面包机（警报成功类型），但没有这样的消息：Toastr without message

我也认为toastr.success("{{ Session::get('$notification') }}");也是尝试过的，但没有任何改变。对此有任何想法吗？？

laravel Toastr显示但没有消息
