【中文标题】在编辑任何输入时呈现数据表单列表?【英文标题】:In listing of data form is rendered when any input edited? 【发布时间】:2020-12-03 23:48:32 【问题描述】:使用 livewire 1.3 / alpinejs 2.x.x 我用过滤器文本列出数据 和选择输入并单击“搜索”按钮我需要运行搜索时 单击“搜索”按钮。 但是,当文本/选择输入失去焦点而没有单击“搜索”按钮时,就会运行搜索。 我通过表单的电线看到它:加载块和日志文件中的 1 行,我在渲染方法中触发 那不是我需要的:我只需要点击“搜索”按钮来运行渲染方法。 我尝试使用 alpinejs,但失败了...... 在组件 app/Http/Livewire/Admin/AppNews.php 我有:
<?php
namespace App\Http\Livewire\Admin;
use Carbon\Carbon;
use Livewire\Component;
use App\News;
use Livewire\WithPagination;
use Livewire\WithFileUploads;
class AppNews extends Component
use WithPagination;
use WithFileUploads;
public $filters = [
'title' => '',
'published' => '',
];
];
public $uploaded_file_name;
public $uploadedImageFilenameData;
public $uploadedNewsImage;
protected $listeners = ['fileUpload' => 'handleFileUpload'];
public $current_news_id;
public $updateMode = 'browse';
public function render()
\Log::info('-1 NewsRENDER $this->filters ::' . print_r($this->filters, true));
$news_rows_count = News
::getByTitle($this->filters['title'], true)
->getByPublished($this->filters['published'], true)
->count();
$backend_per_page = Settings::getValue('backend_per_page', CheckValueType::cvtInteger, 20);
$this->emit('app_news_opened', ['mode' => 'browse', 'id' => null]);
$newsPublishedValueArray = SetArrayHeader([['key' => '', 'label' => ' -Select published- ']], News::getNewsPublishedValueArray(true));
$newsDataRows = News
::getByTitle($this->filters['title'], true)
->getByPublished($this->filters['published'], true)
->with('creator')
->orderBy('news.created_at', 'desc')
->paginate($backend_per_page);
$newsDataIds = [];
foreach ($newsDataRows as $nextNews)
$newsDataIds[] = $nextNews->id;
return view('livewire.admin.app-news.container', [
'newsDataRows' => $newsDataRows,
'newsDataIds' => $newsDataIds,
'form' => $this->form,
'news_rows_count' => $news_rows_count,
'newsPublishedValueArray' => $newsPublishedValueArray,
]);
在模板 resources/views/livewire/admin/app-news/container.blade.php 中:
<article class="admin_page_container">
<div class="card form-admin-news">

<div class="spinner-border" role="status" wire:loading>

</article> <!-- page_content_container -->
哪种方式有效?
修改块 2:
我尝试使用 alpinejs2 的另一种方式:我尝试在这种情况下使用它,就像组件的公共 var 更改时一样: 单击“搜索”按钮时使用调度方法
<div class="card form-admin-facilities" x-data="adminFacilitiesComponent()">
...
filter_name: $filter_name<br>
...
temp_filter_name: <span x-html="temp_filter_name"></span><br>
...
<fieldset class="bordered text-muted p-2 m-2">
<legend class="bordered">Filters</legend>
<div class="content_with_right_button" wire:model.lazy="filter_name">
<div class="content_with_right_button_left_content" >
<input
class="form-control admin_filter_input"
x-model="temp_filter_name"
type="text"
>
</div>
<div class="content_with_right_button_right_button pl-2" >
<button class="btn btn-outline-secondary" @click="$dispatch('input', temp_filter_name)" type="button">Search
</button>
<!-- In more complicated form can be several filter fields : text and select inputs -->
</div>
</div>
</fieldset> <!-- Filters -->
...
<script>
function adminFacilitiesComponent()
return
temp_filter_name:'',
在组件中我定义了 public $filter_name var,它用于 render 方法:
class Facilities extends Component
public $form= [
'name'=>'',
'descr'=> '',
'created_at'=> '',
'is_reopen' => false,
];
public $current_facility_id;
public $filter_name= '';
public $updateMode = 'browse';
public function render()
\Log::info( '-1 render Facilities $this->filter_name ::' . print_r( $this->filter_name, true ) );
$this->facility_rows_count = Facility
::getByName($this->filter_name, true)
->count();
$backend_per_page = Settings::getValue('backend_per_page', CheckValueType::cvtInteger, 20);
return view('livewire.admin.facilities.container', [
'facilityDataRows' => Facility
::orderBy('created_at', 'desc')
->getByName($this->filter_name, true)
->paginate($backend_per_page),
'facility_rows_count'=> $this->facility_rows_count
]);
但它不像我预期的那样工作:当这个输入失去焦点时在文本输入中输入值 表格再次呈现。我希望只有在单击“搜索”按钮时才会呈现表单 表单将使用新输入的值呈现。我不使用模糊事件进行文本输入和 不明白为什么当这个输入失去焦点时会呈现表单?
修改版块 3: 使用 x-ref= 我这样做:
<div class="content_with_right_button" wire:model.lazy="filter_name">
<div class="content_with_right_button_left_content" >
<input
class="form-control admin_filter_input"
x-model="temp_filter_name"
x-ref="searched"
type="text"
> 1111111
</div>
<div class="content_with_right_button_right_button pl-2" >
<button class="btn btn-outline-secondary nowrap_block" wire:click="makeSearch(this.$refs.searched)" type="button">
Search
</button>
</div>
</div>
但我点击搜索按钮时出错:
VM1983:6 Uncaught TypeError: Cannot read property 'searched' of undefined
at eval (eval at parseOutMethodAndParams (directive.js:55), <anonymous>:6:27)
at _default.parseOutMethodAndParams (directive.js:55)
看起来无法使用 this.$refs。价值在
wire:click="makeSearch .
我需要触发组件方法
public function makeSearch($search_value='')
并将输入的值发送到其中。 看起来我尝试的方式无效。 如果有有效的方法?
谢谢!
【问题讨论】:
查看修改后的 BLOCK 2 我仍在寻找决定。如何实施?谁有类似问题:请分享您的经验。 【参考方案1】:为了使 livewire 忽略组件,只需将 wire:ignore
添加到已修改块 2 中组件的 div 中,然后在您的 dispatch
方法中,您可以编写单击按钮后发生的逻辑。
【讨论】:
能否请您详细说明>>>在您的调度方法中,您可以编写之后发生的逻辑 @mstdmstd 例如,如果您想要按钮单击时输入的值,那么您可以将x-ref=searched
分配给input
元素并通过'$refs.searched
或@987654326 获取它的值@当点击搜索按钮或任何你喜欢的时候
请您看一下修改后的 BLOCK 3【参考方案2】:
在您修改的块 2 中,您应该在 AlpineJS 组件的基本 div 中使用 wire:ignore
。这将使 livewire 忽略该组件。
<div class="card form-admin-facilities" wire:ignore x-data="adminFacilitiesComponent()">
您的$dispatch()
应该在您单击按钮时处理设置值。
【讨论】:
能否提供一个链接到描述它的文档? 是的,wire:ignore 有帮助。您能否解释一下 $dispatch 中必须包含的内容(输入模糊?)?以上是关于在编辑任何输入时呈现数据表单列表?的主要内容,如果未能解决你的问题,请参考以下文章
