【问题描述】：
我在页面上有一个表，我可以从数据库中获取数据并将其加载到表中。现在我想在同一页面上创建应用过滤器选项，并且表中的数据应该被过滤帐户以应用过滤器。我是 Laravel 和 PHP 的新手，所以尝试了多个选项来过滤可以使用 ajax 完成的找到的选项，jquery 也尝试过，但没有运气。 这是我的示例刀片模板，我可以从列中获取不同的值并将其加载到下拉列表中，但我想要做的是单击应用按钮，表下的数据应根据过滤器进行更新。
@section('content')

<td>这是我的 Memeberdetails 控制器，它是一个资源控制器
<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Models\Memberdetails;
use App\Models\Attrition_correlators;
class MemberdetailController extends Controller
{
/**

public function __construct()
{
$this->middleware('auth');
}
public function index()

$Region_select = Memberdetails::distinct('Region')->get(['Region']);
return view('admin.members.Datapoints',compact('Memberdetails_list','Business_unit','Org_level1','Org_level2','Region_select'));
}
/**

//
}
/**

*/
public function destroy($id)
{
//
}
}这是我的 web.php
Route::resource('/Memberdetails', MemberdetailController::class);下面是我的迁移
public function up()
{
Schema::create('memberdetails', function (Blueprint $table) {
$table->id();
$table->string('membersid');
$table->string('Role');
$table->string('Orglevel1');
$table->string('Orglevel2');
$table->string('Region');
$table->string('Professional_clas');
$table->string('Performance');
$table->string('Probablity');
$table->string('Riskzone');
$table->string('Manager');
$table->string('Topcorrelators');
$table->string('Local_Expat');
$table->string('Role_Seniority');
$table->string('HR_Region');
$table->string('Gender');
$table->string('Marital_Status');
$table->string('Business_Unit');
$table->string('Total_Working_years');
$table->timestamps();
});
}我想知道我可以做些什么来使过滤器正常工作，以及我怎样才能在业务部门上级联 Orgleve1 和 Orgleve2..这意味着当我选择业务部门相关的 Org 级别 1 和 Orglevel2 时应该填充下拉列表并且过滤器应该。 任何帮助都会真正帮助我 提前致谢！
