Laravel Blade without extra whitespace?
提问by Citizen
If you do this you get an error:
如果你这样做，你会得到一个错误：
<p>@if($foo)@if($bar)test@endif@endif</p>
And if you do this, you get <p> test </p>, adding too much whitepace:
如果你这样做，你会得到<p> test </p>，增加了太多的空白：
<p>@if($foo) @if($bar)test@endif @endif</p>
Is there a way to avoid this?
有没有办法避免这种情况？

this appears to be getting a lot of search traffic so I figured I'd add an update to share how I'm handling this these days. Basically, it's a little more code but it ends up being stupid simple and very clean:
这似乎获得了大量的搜索流量，所以我想我会添加一个更新来分享我这些天是如何处理的。基本上，它是更多的代码，但它最终变得愚蠢简单且非常干净：
@if($foo)
<p>Test</p>
@elseif($bar)
<p>Test2</p>
@else
<p>Test3</p>
@endif
The moral of the story is when you're working with blade, don't try to cram a lot of conditionals within elements. Rather, have the result of the conditional contain the element. It's clean, easy to read, and with only a few more characters spent.
这个故事的寓意是当你使用 Blade 时，不要试图在元素中塞满很多条件。相反，让条件的结果包含元素。它干净，易于阅读，并且只用了几个字符。

Try with a ternary operator, there is no whitespace control in Laravel
尝试使用三元运算符，Laravel 中没有空格控制
<p>{{ $foo ? ($bar ? 'test' : '') : ''}}</p>

You could always use the hedronium/spaceless-bladepackage on packagist to add this functionality to Blade.
您始终可以使用packagist 上的 hedronium/spaceless-blade包将此功能添加到 Blade。

As far as I know there is no spacelesstag in Blade. If you want to use standard Blade tags you will have extra spaces. There is a github discussionwith proposal for new tag
据我所知spaceless，Blade 中没有标签。如果您想使用标准 Blade 标签，您将有额外的空间。有一个关于新标签提案的github 讨论

You can add {{""}} in between the code you want to close or connect without space.
您可以在要关闭或连接的代码之间添加 {{""}} 而不留空格。
@if($foo)@if($bar)test@endif{{""}}@endif
@if($foo)@if($bar)test@endif{{""}}@endif
