Blade中的Section和Stack有什么区别? [英] What is the difference between Section and Stack in Blade?
问题描述
我们可以使用section定义一些HTML，然后使用yield定义其他地方.
We can use a section to define some HTML and then yield that somewhere else.
那为什么要有栈呢? https://laravel.com/docs/5.2/blade#stacks
So why do we have stacks? https://laravel.com/docs/5.2/blade#stacks
使用不同的关键字可以做完全相同的事情，但是选项较少(没有继承).
It's doing exactly the same thing with different keywords, but has fewer options (No inheritance).
@push('scripts')
<script src="/example.js"></script>
@endpush
<head>
<!-- Head Contents -->
@stack('scripts')
</head>
可以通过以下部分完成:
Can be done with section:
@section('scripts')
<script src="/example.js"></script>
@endsection
<head>
<!-- Head Contents -->
@yield('scripts')
</head>
推荐答案
我可能会误会，但是区别不仅在语义上，而且在行为上也是如此. 使用 @push ，您可以追加到堆栈中所需的次数，而(默认情况下)您可以仅一次填充 @section . 在某些情况下，当您需要跨模板文件或循环添加来自不同位置的内容时，这会派上用场:
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:
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
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>
