Question

如官方文档所示，我在select中实现了select2，但我无法使其完全发挥作用。

<div>
<div wire:ignore>
    <select class="js-example-basic-single" name="state">
        <option value="AL">Alabama</option>
        <option value="WY">Wyoming</option>
    </select>

    <!-- Select2 will insert it's DOM here. -->
</div>

@push('scripts')
<script>
    $(document).ready(function() {
        $('.js-example-basic-single').select2();
        $('.js-example-basic-single').on('change', function (e) {
            @this.set('foo', e.target.value);
        });
    });
</script>
@endpush

如果我在视图中删除以下脚本，则select2组件可以正常显示

$('.js-example-basic-single').on('change', function (e) {
                @this.set('foo', e.target.value);
            });

但是我当然失去了想要的功能。

我使用的selct2添加链接如下

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
<script src="{{asset('SitioWeb/assets/select2/js/select2.min.js')}}"></script>

我想念什么？

您可以使用Bootstrap选择

npm install bootstrap-select

对我来说效果很好。这是我的代码。

<div class="form-group">
    <label for="permissions">{{ __('role.permissions') }}</label>
    <div class="col-sm-10">
        <div wire:key="UNIQUE_KEY">
            <div wire:ignore>
                <select id="permissions" wire:model="permissions"
                        data-live-search="true"
                        data-actions-box="true"
                        title="{{__('generic.select')}} {{ __('role.permissions') }}"
                        name="permissions[]" data-width="100%"
                        class="selectpicker permissions" multiple>
                    @foreach($list_permission as $permission)
                        <option value="{{ $permission->id }}"
                                data-subtext="{{ $permission->key }} {{ ' -'. $permission->table_name }}">

                            {{ __('permission.'.$permission->key) }}
                        </option>
                    @endforeach
                </select>
            </div>
        </div>
        @error('permissions') <span class="text-danger">{{ $message }}</span> @enderror
    </div>
</div>

在脚本中：

   ....
   @push('scripts')
        <script>
            Livewire.restart();
            $(function () {
                $('.permissions').selectpicker();
            });
        </script>
    @endpush
</div>

在组件中

public $permissions = [];
public $old_permissions = [];

public function updatedPermissions()
{
    $filter_arrays = array_filter($this->permissions);
    $unique = array_unique($filter_arrays);
    $this->permissions = $unique;
}

更新中：

 if (! empty($this->old_permissions)){
     $updateRole = $this->role->find($this->modelId)->permissions()->detach();
     $updateRole = $this->role->find($this->modelId)->permissions()->sync($validatedData['permissions']);

  }elseif ($this->old_permissions != $this->permissions ){
     $updateRole = $this->role->find($this->modelId)->permissions()->attach($validatedData['permissions']);
   }

Answer 2

我努力将livewire与select2结合在一起，最终找到了解决方案。

UsersComponent.php

class Users extends Component
{
    public $users = [];

    public function mount()
    {
        $this->users= User::all();
    }

    public function render()
    {
        return view('livewire.users');
    }
}

然后

users.blade.php

<div class="col-sm-12 col-xl-3 m-b-30" wire:ignore >
    <div >
        <h4 class="sub-title" >USERS</h4>
        <select class="js-example-basic-single form-control-warning" name="states" >

            @foreach ($users as $user)
                <option value="{{ $user->id }}">{{ $user->name}}</option>
            @endforeach

        </select>
    </div>

</div>

index.blade.php

<p>
@livewire(livewire.users)
</p>

Laravel Livewire上的select2不起作用
