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

Question

我有数据 return 通过 ajax 响应以 json 格式从控制器编辑，我可以在控制台中打印数据。但是我想在table中显示，怎么显示呢？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 return 作为响应，所以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') }}',

                dataType: 'json',
                success:function(response){
                    //console.log(response);
                });

             });
        })
    </script>

我能告诉的最好方法是为那个 table 制作一个 blade 并像往常一样在控制器中为那个视图制作 return 数据：

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

并且在您的 blade 中再次像往常一样在您的 table

中使用 laravel 渲染数据

所以 laravel 将 return 一个 blade 到你的 ajax-success 方法

并且在您的成功方法中，您可以执行以下操作：

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

无论你想让你的 table 放在什么地方，只要把这个 div:

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