Question

我有2个foreach在1选择与不同的组。如果从2nd optgroup中选择值，我想将输入从serviceid更改为domain id。

<select class="form-control select2" id="serviceid" name="serviceid" required>
   <option disabled selected value> -- Select -- </option>
   <optgroup label="Products">
       @foreach($services['product'] as $service)
           <option value="{{ $service['id'] }}">{{ $service['name'] }}</option>
       @endforeach  
   </optgroup>

   <optgroup label="Domains">
       @foreach($domains['domain'] as $domain)
           <option value="{{ $domain['id'] }}">{{ $domain['domainname'] }}</option>
       @endforeach  
   </optgroup>

</select>

现在输出始终带有"serviceid" => "2" 如果从标签Domains 2nd array中选择了某些东西，我想要"domainid" => "1"。

您可以使用隐藏输入来处理这两种情况，例如下面显示的代码段，您可以使用服务器端代码中的非空代码进行过滤。

希望这有帮助。

$('#serviceid').select2();

$('#serviceid').on('change', function() {
  var label = $('#serviceid :selected').parent().attr('label');

  if (label == "Domains") {
    $('.domainid').val($(this).val());
    $('.serviceid').val("");
  } else if (label == "Products") {
    $('.serviceid').val($(this).val());
    $('.domainid').val("");
  }

  console.log('domainid=' + $('.domainid').val());
  console.log('serviceid=' + $('.serviceid').val());
});
