Laravel 5 - 仅在特定 page/controller(页面特定资产)上添加样式表

Laravel 5 - Add a stylesheet only if on a certain page/controller (page specific asset)

我的 Laravel 布局目前如下(删除了导航栏等):

<link href="//maxcdn.bootstrapcdn.com/bootswatch/3.3.4/flatly/bootstrap.min.css" 
     rel="stylesheet">
<link href="{{ asset('/css/app.css') }}" rel="stylesheet">

<!-- Fonts -->
<link href='//fonts.googleapis.com/css?family=Roboto:400,300' rel='stylesheet' 
    type='text/css'>

<!-- Scripts -->
<script src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

<!-- HTML5 shim and Respond.js for IE8 support of HTML5 elements and media queries -->
<!-- WARNING: Respond.js doesn't work if you view the page via file:// -->
<!--[if lt IE 9]>
    <script src="https://oss.maxcdn.com/html5shiv/3.7.2/html5shiv.min.js"></script>
    <script src="https://oss.maxcdn.com/respond/1.4.2/respond.min.js"></script>
    <![endif]-->
</head>
<body>

    <div class="container">

        @yield('content')

    </div>

    <!-- Scripts -->
    <script src="//maxcdn.bootstrapcdn.com/bootstrap/3.3.4/js/bootstrap.min.js"></script>
    <script src="{{ asset('assets/vendor/toastr/toastr.min.js') }}"></script>
</body>
</html>

然后我将视图附加到布局:

@extends('app')

@section('content')

Content here.

@endsection

我很困惑,例如,如果我在 clinicController.php 或诊所路线内(这是一种资源),那么 "inject" 样式表和 Javascript 文件放到合适的地方。

有办法吗?我想 @if on a certain page, display this 会起作用,但我确定必须有更多 "Laravel" 的方法来做到这一点?

如有任何帮助,我们将不胜感激。

您可以在 view 中创建如下所示的 section,例如:

@extends('layouts.master')

@section('styles')
    <link href="{{asset('assets/css/custom-style.css')}}" />
@stop

然后也在你的layout@yield那,例如:

<!--Static StyleSheets-->
<link href="{{asset('assets/css/common-style.css')}}" rel="stylesheet" />

<!--Dynamic StyleSheets added from a view would be pasted here-->
@yield('styles')

同样适用于 script 标签,例如(layoutstyles / scripts 可能看起来像这样):

<html>
    <head>
        <!--Static StyleSheets-->
        <link href="{{asset('assets/css/common-style.css')}}" />

        <!--Dynamic StyleSheets added from a view would be pasted here-->
        @yield('styles')
    </head/>

    <!-- Template Body -->
    <body>
        <!-- Other HTML Elements -->
        <div class="container">
            @yield('content')
        </div>

        <!-- Dump all dynamic scripts into template -->
        @yield('scripts')
    </body>
</html>

更新:由于Laravel 5.2,可以使用Stacks作为styles/scripts,例如:

在视图中:

@extends('layouts.master')

@section('content')
    <!-- Content -->
@endsection

<!-- Push a style dynamically from a view -->
@push('styles')
    <link href="{{asset('assets/css/common-style.css')}}" />
@endpush

<!-- Push a script dynamically from a view -->
@push('scripts')
    <script src="/example.js"></script>
@endpush

模板:

<html>
    <head>
        <!--Static StyleSheets-->
        <link href="{{asset('assets/css/common-style.css')}}" />

        <!--Dynamic StyleSheets added from a view would be pasted here-->
        @stack('styles')
    </head/>
    <!-- Template Body -->
    <body>

        <!-- Other HTML Elements -->
        <div class="container">
            @yield('content')
        </div>

        <!-- Dump all dynamic scripts into template -->
        @stack('scripts')

    </body>
</html>

如果您像我一样不喜欢在多个视图文件中乱扔脚本的想法,您可以使用以下任一方法在模板中以可维护的方式进行:

如果使用命名路由

@if (in_array(Route::currentRouteName(), ['profile', 'register']))
    <script src="example.js"></script>
@endif

(同上)

@if (in_array(\Request::route()->getName(), ['profile', 'register']))
    <script src="example.js"></script>
    <script src="another.js"></script>
@endif

改为检查控制器操作

  @if (in_array(substr(Route::currentRouteAction(), strpos(Route::currentRouteAction(), '@')+1), ['create', 'edit']))
    <script src="example.js"></script>
  @endif

指定控制器和动作

  @if (in_array(substr(Route::currentRouteAction(), strpos(Route::currentRouteAction(), 'Controllers')+12), ['UserController@create', 'AlbumController@edit']))
    <script src="example.js"></script>
  @endif
