使用livewire 1.3/alpinejs 2。x、 我用过滤文本和选择输入列出数据，点击“搜索”按钮，我需要在点击“搜索”按钮时运行搜索。但当文本/选择输入失去焦点而未点击“搜索”按钮时，搜索将运行。我通过表单的连线看到它：加载块和日志文件中的一行，我在render方法中触发它，这不是我所需要的：我只需要点击“搜索”按钮来运行render方法。我尝试使用alpinejs，但失败了。。。在组件app/Http/Livewire/Admin/AppNews中。我有：

哪种方式有效？
修改的第2块：
我尝试使用alpinejs2的另一种方法：我尝试在这种情况下使用它，就像当组件的公共变量被更改时一样：当单击按钮“搜索”时使用dispatch methid
<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，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'=> $this->facility_rows_count
]);
}
但它并不像我期望的那样工作：当文本输入失去焦点时，再次呈现输入值。我希望只有当我点击“搜索”按钮时，表单才会呈现，表单会以新输入的值呈现。我不使用模糊事件的文本输入，不明白为什么当输入失去焦点时，表单会呈现？
修改块3：使用x-ref=I do：
<div class="content_with_right_button" wire:model.lazy="filter_name">
<div class="content_with_right_button_left_content" >
<input
class="form-control admin_filter_input"
x-model="temp_filter_name"
x-ref="searched"
type="text"
> 1111111
</div>
<div class="content_with_right_button_right_button pl-2" >
<button class="btn btn-outline-secondary nowrap_block" wire:click="makeSearch(this.$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)
看起来不可能用这个$裁判。价值
wire:click="makeSearch .
我需要触发成分法
public function makeSearch($search_value='')
{
并将输入的值发送到其中。看来我尝试的方式是无效的。如果有有效的方法？
谢谢
在修改后的block 2中，应该在AlpineJS组件的base 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()">
单击按钮时，$dispatch（）应负责设置值。
为了使livewire忽略组件，只需将wire:ignore添加到修改块2中组件的div中，然后在dispatch方法中，您可以编写单击按钮后发生的逻辑。
