Laravel Blade 中的 Section 和 Stack 有什么区别

发布于02月28日

We can use a section to define some HTML and then yield that somewhere else.

那我们为什么要有堆栈呢？https://laravel.com/docs/5.2/blade#stacks

它用不同的关键字做完全相同的事情，但选项较少(没有继承).

@push('scripts')
    <script src="/example.js"></script>
@endpush

<head>
    <!-- Head Contents -->

    @stack('scripts')
</head>

可通过以下部分完成:

@section('scripts')
    <script src="/example.js"></script>
@endsection

<head>
    <!-- Head Contents -->

    @yield('scripts')
</head>

推荐答案

I might be mistaken, but the difference is not only semantically, but in behaviour as well. With @push you append as many times as needed to a stack, while (by default) you may fill @section only once in your views. In some situations this comes in handy when you need to add content from different locations across your template files or in loops:

index.blade.php:

@extends('master')

...  

@for ($i = 0; $i < 3; $i++)

  @push('test-push')
    <script type="text/javascript">
    // Push {{ $i }}
    </script>
  @endpush

  @section('test-section')
    <script type="text/javascript">
    // Section {{ $i }}
    </script>
  @endsection

@endfor

master.blade.php

    @stack('test-push')
    @yield('test-section')
</body>

结果:

    <script type="text/javascript">
    // Push 0
    </script>
        <script type="text/javascript">
    // Push 1
    </script>
        <script type="text/javascript">
    // Push 2
    </script>
    <script type="text/javascript">
    // Section 0
    </script>
    </body>
