如何在livewire中从一个组件向另一个组件发射和侦听值?

大家好,我是livewire的新手,我正在尝试发送 $this->wil 从…起 FormElements.php 组件到 form.php 组件,并将其渲染到balde文件上。

这是我的 FormElements.php 密码

class FormElements extends Component
{

    public $deliveryFees = 0;
    public $wil = 'Blida';
    public $fees = [];
    
    public function deliveryFees()
    {
        $this->deliveryFees;
        //dd($this->deliveryFees);
    }
    public function render()
    {
        $destination = DB::table('delivery_fees')->select('*')->pluck('destination');
        return view('livewire.form-elements', compact('destination'));
    }

    public function updatedWil()
    {
        $this->fees = DeliveryFee::select('stopdesk', 'domicile','id')
            ->where('destination', $this->wil)
            ->get()->toJson();
        $fees = ($this->fees);
        return view('livewire.form-elements', ['json' => $fees]);
    }
}

$this->wil 是一个动态值,当从下面的代码中选择选项值时会发生变化:

<select id="wilaya" wire:model="wil"
   class="w-full dropdown-toggle  items-center justify-between rounded-lg border border-jacarta-100
      bg-white py-3 px-3 dark:border-jacarta-600 dark:bg-jacarta-700 dark:text-jacarta-300"
        onchange="closeFunction()">
          @foreach ($destination as $items)
             <option value="{{ $items }}">{{ $items }}</option>
          @endforeach
     <input type="hidden" name="wilaya" value="{{ $wil }}">
 </select>

另一方面,我有 Form.php 组成部分

 public function render()
    {
        $wilayas = Wilaya::where('nom','Alger')->first();

        dd($wilayas->id);

        if (!empty($wilayas)) {
            
            $communes = Commune::where('wilaya_id',$wilayas->id)->get();
        }else{
            $communes = [];
        }
        return view('livewire.form',compact('wilayas' , 'communes'));
    }

我想听听发送的值,并将其放在这行代码中 $wilayas = Wilaya::where('nom',$this->wil)->first(); 这样我就可以拿到 nom 基于的值 $this->wil .

我希望我的问题很清楚。请随时告诉我实现我的想法的简单方法。

提前谢谢。
