You could return an json_encoded array from the controller like so:
您可以像这样从控制器返回一个 json_encoded 数组：
public function index()
{
$posts = Post::all();
$json = json_encode($posts);
return View::make('posts.index', compact('posts', 'json'));
}
Which you then can work on in your view like you'd like:
然后您可以按照自己的意愿在您的视图中进行处理：
<script type="text/javascript">
var data = {{ $json }};
console.log(data);
</script>
Also, if you have sensitive fields on your post model, you should exclude these in the model class to prevent them to show in your javascript inspector:
此外，如果您的帖子模型中有敏感字段，您应该在模型类中排除这些字段以防止它们显示在您的 javascript 检查器中：
class Post extends \Eloquent {
...
protected $hidden = array(
'id',
'created_at',
'updated_at'
);
...
}

Use Eloquents built in function toJsonto get your rows as json.
使用内置函数的 EloquentstoJson将您的行作为 json。
<script type="text/javascript">
var data = "{{ $posts->toJson() }}";
console.log(data);
</script>
If there's some fields you don't want to include, add the field to the hiddenproperty in your model as Jimmy mentioned.
如果您不想包含某些字段hidden，请按照Jimmy 提到的方法将该字段添加到模型中的属性中。

If you looking for "high-level" way to convert plain array to json, you can use laravel collections.
如果您正在寻找将普通数组转换为 json 的“高级”方法，您可以使用 laravel 集合。
collect(['a' => 1, 'b' => 2, 'c' => 3])->toJson();

you don't need to do all that, just use the php inbuilt function json_encode
你不需要做所有这些，只需使用 php 内置函数 json_encode
$json = json_encode($posts);
echo $json;
<script type="text/javascript">
var data = "$json"; // ??
console.log(data);
</script>
