如何根据其值在HTML单元格中添加类

Question

我有以下循环，其中我从查询中提取值并用表编写表，在该字段中，我需要根据从发货日期到今天为止所经过的天数，更改年龄的字段我已经在CSS中尝试过了[data-age> 180]，但是我只遇到错误，而且找不到与我的需求类似的情况，另外，id喜欢在循环内进行操作，而不是另外的代码，因为它弄乱了我的视线@foreach($shipments as $shipment)  <tr>    <td data-title="id">{{$shipment->id}}</td>    <td class=tracking data-title="tracking">{{$shipment->tracking}}</td>    <td data-title="PartNumber">{{$shipment->PartNumber}}</td>    <td data-title="DateShipped">{{$shipment->DateShipped}}</td>    <td       data-title="age"       data-age="{{        (int) floor(          (time() - strtotime($shipment->DateShipped))           / (60 * 60 * 24)        )      }}"    >{{      (int) floor(        (time() - strtotime($shipment->DateShipped)) / (60 * 60 * 24)      )    }} days    </td>    <td data-title="Qtyorder">{{$shipment->Qtyorder}}</td>    <td data-title="QtyShipped">{{$shipment->QtyShipped}}</td>    <td data-title="QtyBckorder">{{$shipment->QtyBckorder}}</td>    <td data-title="purchaseOrder">{{$shipment->purchaseOrder}}</td>    <td data-title="OrderNumber">{{$shipment->OrderNumber}}</td>    <td data-title="paperwork">{{$shipment->paperwork}}</td>    <td data-title="VMIreceived">{{$shipment->VMIreceived}}</td>    <td data-title="VMIticketNumber">{{$shipment->VMIticketNumber}}</td>    <td data-title="VMILRB">{{$shipment->VMILRB}}</td>    <td>      <a         href="{{ route('shipment.edit',$shipment->id)}}"         class="btn btn-primary"      >        Edit      </a>    </td>    <td>      <form action="{{ route('shipment.destroy', $shipment->id)}}" method="post">        @csrf        @method('DELETE')        <button class="btn btn-danger" type="submit">Delete</button>      </form>    </td>  </tr>@endforeach

Answer 1

未经测试，但是您可以尝试以下操作：

@foreach($shipments as $shipment)

  @php

    $time_passed = $shipment->DateShipped->diffInSeconds(now());

  @endphp

  <tr>

    <td class="{{ time_passed > some_number ? 'class_value_if_true' : 'class_value_if_false' }}">

      {{ $time_passed }}

    </td>

  </tr>

@endforeach

Answer 2

尝试一行if语句

{{ $condition ? value if true : value if false }}
