只是尝试一下Livewire，一路上我被卡住了。我到了需要传递dom元素值的阶段，但不确定这样做的最佳实践是什么，甚至不确定是否可以通过livewire？
视图：
<div>
<textarea class="form-control mb-3" wire:keydown.enter="addComment('Guest', 'This textareas value here')"></textarea>
<hr>
@foreach ($comments as $comment)
<div class="card mt-4" style="background-color: deeppink">
<div class="card-body">
<h5 class="card-title">{{ $comment['author'] }}</h5>
<p class="card-text">{{ $comment['body'] }}</p>
</div>
</div>
@endforeach
</div>
组成部分：
<?php
namespace App\Http\Livewire;
use Livewire\Component;
class Comments extends Component
{
public $comments = [
[
'author' => 'John Doe',
'body' => 'I really like short walks through the park near my house.',
],
[
'author' => 'Samantha Hox',
'body' => 'Did you know, that Lions are actually bigger than the size you imagined. They are beautiful creatures so they are.',
],
];
public function render()
{
return view('livewire.comments');
}
public function addComment($author, $body) {
array_unshift($this->comments, [
'author' => $author,
'body' => $body
]);
}
}
您只需使用wire:model=“$param”
public $author = '';
public $body = '';
public $comments = [
[
'author' => 'John Doe',
'body' => 'I really like short walks through the park near my house.',
],
[
'author' => 'Samantha Hox',
'body' => 'Did you know, that Lions are actually bigger than the size you imagined. They are beautiful creatures so they are.',
],
];
public function mount()
{
$this->author = 'Guest'; // set default value to Guest
}
public function render()
{
return view('livewire.comments');
}
public function addComment() {
array_unshift($this->comments, [
'author' => $this->author,
'body' => $this->body
]);
$this->reset(['body']); // reset back to default value i.e. empty
}
必应body文本区域并删除参数。
<textarea class="form-control mb-3" wire:model='body' wire:keydown.enter="addComment()"></textarea>
