Question

尝试了所有可能的解决方案来刷新组件，但失败了。是否有任何选项不推送新评论并刷新 $comments 变量包含的任何内容？

想要在单击发送按钮时刷新 $comments 及其与刀片中回复的关系

在发送按钮上调用 $refresh 操作，但它似乎不起作用。甚至尝试使用 $this->render() 重新渲染组件。这也失败了。

<div>
    @foreach($comments as $item)
    <div class="row" @if($item->reply_id != null) style="margin-left:40px;" @endif>
        <div class="col-md-12">
            <div class="py-md-4 py-3 border_bottom" >
            <div class="row">
                <div class="col-md-1 col-sm-1 col-1">
                <div class="rating_person pt-3">
                    <img src="{{ isset($item->owner->profile_picture) ? asset($item->owner->profile_picture) : asset('images/default.jpg') }}">
                </div>
                </div>

由于没有更新任何属性，livewire 聊天组件将不会刷新。

可能的解决方案不是将列表作为参数传递，而是在聊天组件中获取它。使用事件触发刷新：

@click="$emit('discussion.chat.{{ $id }}.refresh')"

里面frontend.discussion-chat有一个

public function listeners(): array
{
    return [
        "discussion.chat.$this->id.refresh" => "reload"
    ];
}

public function reload(): void
{
    // E.g.
    $this->comments->fresh();
}

在 livewire 中单击时无法刷新组件
