Pau*_*ulH 5 php laravel laravel-livewire
使用 Laravel Livewire,我有一个父母和一个(重复的)孩子。子刀片有一个呼叫childMethod()through wire:click="childMethod()"。
问题是当parent->childMethod()我想child->childMethod()被呼叫时却被呼叫了。
父组件
class StatementsTable extends Component // parent
{
public function render()
{
return view('livewire.statements-table', [
'statements' => Statement::limit(10)->get()
]);
}
}

@livewire('statement-line', ['statement' => $statement], key($statement->id))
@endforeach

子组件:
class StatementLine extends Component
{
public $statement;
public $calls = 0;
public function childMethod()
{
$this->calls += 1;
}
public function mount($statement): void
{
$this->statement = $statement;
}
public function render()
{
return view('livewire.statement-line');
}

您可以在 livewire 中确定回调的范围,查看此处提供的文档https://laravel-livewire.com/docs/2.x/events#scoping-events
对于你的情况,你应该像这样自我调整
<button wire:click="$emitSelf('childMethod')">
