with livewire 1.3 / alpinejs 2.x.x I make listing of data with filter text and selection inputs and clicking on “Search” button I need to run search when “Search” button is clicked. But search is run when text/selection input lose focus without clicking on “Search” button. I see it by form's wire:loading block and 1 line in log file, which I trigger in render method That is not what I need : I need to run render method only clicking on “Search” button. I tried to use alpinejs, but failed... In component app/Http/Livewire/Admin/AppNews.php I have:

<?php

Which is the valid way?

Modified BLOCK 2:

I try another way with using of alpinejs2 : I try to use it in this case, as when public var of component is changed: with dispatch methid when button “Search” is clicked

<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:'',

and in the component I defined public $filter_name var, which is used in render method :

   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
        ]);
        }

But it does not work as I expect : entering value in text input when this input lose focus form is rendered again. I expected form to be rendered only when I click on “Search” button and form will be rendered with new entered value. I do not use blur event for text input and do not understand why the form is rendered when this input lose focus?

Modified BLOCK 3: Using 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>

But I got error clicking on search button:

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)

Looks like it is impossible to use this.$refs. value in

wire:click="makeSearch    .

I need to trigger component method

public function makeSearch($search_value='')
{

and send entered value into it. Looks like the way I tried was invalid. If there is a valid way?

Thanks!

Look at Modified BLOCK 2mstdmstd
I still search for a decision. How it can be implemented ? Who have similar issue : please share your expiernce.mstdmstd

In your modified block 2, you should use wire:ignore in base div of your AlpineJS component. This will make livewire ignore the component.

<div class="card form-admin-facilities" wire:ignore x-data="adminFacilitiesComponent()">

Your $dispatch() should handle setting the value when you click the button.

In order to make livewire ignore the component just add wire:ignore to your component's div in modified block 2 and then in your dispatch method you can write the logic that happens after clicking the button.
