Arrays 在laravel blade中填充数组的组数据

我有这样的数组，我想用foreach循环在laravelblade中填充它。 我的问题是：-

$data['cities'] = Shop::groupBy('area')->select('area', 'city')->get()->groupBy('city')->toarray();

        [1] => Array
            (
                [area] => khan bakeri
                [city] => rawalpindi
            )

        [2] => Array
            (
                [area] => stadium road
                [city] => rawalpindi
            )

    )

[islamabad] => Array
    (
        [0] => Array
            (
                [area] => i9 markaz
                [city] => islamabad
            )

        [1] => Array
            (
                [area] => Street 111
                [city] => islamabad
            )

    )

排列 ( [rawalpindi]=>阵列 ( [0]=>阵列 ( [区域]=>6路 [城市]=>拉瓦尔品第 )

        [1] => Array
            (
                [area] => khan bakeri
                [city] => rawalpindi
            )

        [2] => Array
            (
                [area] => stadium road
                [city] => rawalpindi
            )

    )

[islamabad] => Array
    (
        [0] => Array
            (
                [area] => i9 markaz
                [city] => islamabad
            )

        [1] => Array
            (
                [area] => Street 111
                [city] => islamabad
            )

    )

您可以在blade中这样显示它：

        [1] => Array
            (
                [area] => khan bakeri
                [city] => rawalpindi
            )

        [2] => Array
            (
                [area] => stadium road
                [city] => rawalpindi
            )

    )

[islamabad] => Array
    (
        [0] => Array
            (
                [area] => i9 markaz
                [city] => islamabad
            )

        [1] => Array
            (
                [area] => Street 111
                [city] => islamabad
            )

    )

@foreach($cities as $city => $areas)
  <h1>{{ $city }}</h1>
  @foreach($areas as $area)
    {{ $area['area'] }} <br>
  @endforeach
@endforeach

@foreach（$city作为$city=>$area的城市）
{{$city}
@foreach（$areas$area）
{{$area['area']}}

@endforeach
@endforeach

谢谢，它工作得很好。但是如果我们想用javascript填充它呢？
