从Laravel Blade中的JSON选择值 [英] Select value from JSON inside Laravel Blade

问题描述

我正在使用带有刀片和vuejs的laravel.使用列表控制器，我正在接收所有要显示的用户数据的正确响应.

I'm using laravel with blade and vuejs. Using a controller for a list I am receving the correct response with all the users data to show.

其中一些字段是json数据，我不明白如何检索单个值.

Some of this fields are json data and I can't understand how to retrieve single value.

`@foreach ($lista as $freelance)
  <md-table-row>
    <md-table-cell>
      {{ $freelance->regione }}
     </md-table-cell>
  </md-table-row>
@endforeach`

$ freelance-> regione是JSON，在页面中正确显示为:

$freelance->regione is a JSON, correctly shown in the page as:

`{"text": "Veneto", "value": "Veneto"}`

我的问题是，如何获取JSON响应的单个值而不是所有数据?最好没有循环...我知道我可以为其使用新的循环，但是可能没有.

My question is, how can I get the single value of the JSON response and not all the data? Preferably without loops...I know that I can use a new loop for it but possible no..

推荐答案

在传递$lista变量进行操作之前，请先在控制器中进行尝试.

Try this in your controller before passing the $lista variable to view do this.

foreach($lista as list)
{

 //we will decode the variable befoe passing it to view
 $list->regione = json_decode($list->regione, true);


}

，然后将变量传递给您的视图，例如:

    return View::make('your_view_name', compact('lista'));

然后在刀片视图中.

`@foreach ($lista as $freelance)
  <md-table-row>
    <md-table-cell>
      {{ $freelance->regione['text'] }}
     </md-table-cell>
    <md-table-cell>
      {{ $freelance->regione['value'] }}
     </md-table-cell>
  </md-table-row>
@endforeach`
