如何使用ajax在laravel的刀片页面中显示来自控制器的json响应数据？

如何解决如何使用ajax在laravel的刀片页面中显示来自控制器的json响应数据？

我有json格式的ajax响应从控制器返回的数据，我可以在控制台中打印数据。 但是我想在表格中显示它，我该如何显示呢？ 我搜索了解决方案，但所有解决方案都在控制器函数中写入 HTML 代码并将其作为响应返回，还有其他解决方案吗

我的控制器

<?PHP

namespace App\Http\Controllers\backend;

use App\Http\Controllers\Controller;
use Illuminate\Http\Request;

use App\Category;

class CategoryCtrl extends Controller
{
    //function search - show categories live search
    public function index(Request $request)
    {
        if($request->ajax())
        {
            $categories = Category::where('name','LIKE','%'.$request->cat_search."%")->orderBY('created_at','DESC')->get();
            return Response()->json($categories);
        }
        else {
            $categories = Category::orderBY('created_at','DESC')->get();
            return view('backend.category.list')->withcategories($categories);
        }
    }

}

ajax 代码

<!--  Ajax code for category live search  -->
    <script type="text/javascript">
        $('#cat_search').on('keyup',function(){
            $value = $(this).val();
            $.ajax({
                type : 'get',url : '{{ route('category.index') }}',data:{'cat_search':$value},dataType: 'json',success:function(response){
                    //console.log(response);
                });

             });
        })
    </script>

解决方法

我能说的最好的方法是为该表和控制器制作一个刀片，就像往常一样将数据返回到该视图：

 return view('your-blade-just-for-table')->with('data',$data);

再次像往常一样在刀片中使用 Laravel 在表中呈现数据

所以 laravel 会返回一个刀片到你的 ajax-success 方法

在您的成功方法中，您可以执行以下操作：

    success: function (data) {
            $('.list-group').html(data);
        },

无论你想要你的桌子放在什么地方，只要把这个 div:

<div class="list-group" id="myFileContainer"></div>
