当我更改一个变量的状态时，另一个变量会发生变化，而无需在 laravel 的 livewire 中调用它

问：

我有这个问题：Imgr 视频问题

代码的逻辑是下一个（我使用的是livewire）： 我有两个组件3.1.0

• Table Component
• Modal Component（附在Table Component)

表组件

// Blade
<div>
    // ...
    <button wire:click="openModal">Open Modal</button>
    
    @if($showModal)
        @livewire('modal-component')
    @endif
</div>

// Logic
public $showModal = false;
public function openModal(){ $this->showModal = true; }

#[On('close-modal')]
public function closeModal() {
    $this->showModal = false;
}

模态组件

// Logic
public $departmentValue, $departmentId, $departmentDropdown = false;

public function toogleDepartmentDropdown(){
    $this->departmentDropdown = !$this->departmentDropdown;
}

public function setDepartmentDropdown($id, $value){
    $this->departmentId = $id;
    $this->departmentValue = $value;
    $this->$departmentDropdown = false;
}

public function closeModal(){
    $this->dispatch('close-modal')
}
// Blade
<div>
    <button wire:click="closeModal">Icon Close Button</button>
    
    <button wire:click="toogleDepartmentDropdown">@if($departmentValue){{$departmentValue}}@else - @endif</button>
    @if($departmentDropdown)
        <div>
            @foreach(App\Models\Department::all() as $department)
                <button wire:click="setDepartmentDropdown('{{$department->id}}','{{$department->department_name}}')">{{$department->department_name}}</button>
            @endforeach
        </div>
    @endif
</div>

我不知道我是否必须使用，因为我已经用过它，但它不起作用，所以我不知道下一步要做什么。mount()
