如何 foreach 嵌套在 Laravel Blade 中的动态 JSON

Question

我想在有新数据时动态循环（foreach）这些数据，我该怎么做？ 我使用包laravel-nestedable 。

这是我的返回 JSON，它是动态的：

[
   {
      "id":1,
      "name":"food",
      "slug":"food",
      "child":[
         {
            "id":2,
            "name":"cake",
            "slug":"cake",
            "child":[
               {
                  "id":3,
                  "name":"Rainbow Cake",
                  "slug":"rainbow-cake",
                  "child":[

                  ],
                  "parent_id":2
               },
               {
                  "id":4,
                  "name":"Banana Cake",
                  "slug":"banana-cake",
                  "child":[

                  ],
                  "parent_id":2
               }
            ],
            "parent_id":1
         },
         {

                        "child":[

                        ],
                        "parent_id":6
                     }
                  ],
                  "parent_id":5

您的 Json 数据似乎格式不正确，但如果没有问题，那么您可以将您的 Json 数据从 Controller 发送到 View，如下所示：

return view('your-view')->with('json', $json);

要么

return view('your-view', ['json'=>$json]);

要么

return View::make('your-view')->with('json', $json);

然后在您的刀片文件中，您需要使用 foreach 来获取如下所有数据：

@foreach($json as $data)
    {{ $data->item }}
@endforeach

您还可以将您的 Json 数据转换为数组，然后发送如下：

$array =json_decode( json_encode($json), true);
return view('your-view')->with('array', $array);

然后在您的刀片文件中，您需要使用 foreach 来获取如下所有数据：

@foreach($array as $data)
    {{ $data['item'] }}
@endforeach
