将 DataTable 数据加载到编辑模式

Question

我正在尝试为我的数据创建一个编辑功能 table。数据 table 是使用 Yajra Data table 创建的。一切正常，除非当我尝试将现有数据加载到编辑模式时失败。未显示任何错误，但模态未启动。为了便于参考，我在这里只包含了一小部分代码。

模态：

<!-- Update Status Model Box -->
    <div id="updateStatusModal" class="modal fade" role="dialog">
        <div class="modal-dialog modal-lg">
            <div class="modal-content bg-default">                
                <div class="modal-body">
                    <form class="form-horizontal" id="updateStatus">
                        @csrf
                        @method('PUT')
                        <div class="row">
                            <div class="col">
                                <div class="form-group text-center">
                                    <h6 class="font-weight-bold">Stage 1</h6>
                                    <label for="stage_1" class="switch">
                                        <input type="checkbox" class="form-control" id="stage_1">
                                        <div class="slider round"></div>
                                    </label>
                                </div>
                            </div>                            

                        </div>

                        <div class="row">                            

                            <div class="col">

                                <div class="form-group">
                                    <div class="col-md">
                                        <label for="firstname">Coding</label>
                                        <input type="text" class="form-control" id="first_name" value="" placeholder="Enter Completed Page Count">
                                    </div>
                                </div>
                            </div>
                        </div>
                    </form>
                </div>
                <div class="modal-footer justify-content-between">
                    <button type="button" name="update_btn" id="update_btn" class="btn btn-outline-warning">Update</button>
                </div>
            </div>
        </div>
    </div>

jquery 函数：

// Edit action
    $(document).on('click', '.updateStatus', function(){


        $tr = $(this).closest('tr');

        var data = $tr.clidren("td").map(function(){
            return $(this).text();
        }).get();

        console.log(data);

        $('#id').val(data[0]);
        $('#job_id').val(data[2]);
        $('#stage_1').val(data[3]);
        $('#conversion').val(data[4]);     

        $('#updateStatusModal').modal('show');

    });

我尝试了我发现的这个方法，但它不起作用。任何人都可以在这里给我任何指示吗？

我只是没有看到你的前端脚本（还有后端代码），但我可以分享你需要的我的实现。它与 this (screenshot) 中展示的一样完美。在这里，我将放置前后代码。有编辑现有数据表记录的功能，也有删除记录的功能。

我认为这可以帮助您和其他人构建所需的功能。这里也可以有更多的提示评论，但因为它不小，我可以稍后通过post评论回答。

Answer 2

我正在构建一个 Laravel 类似 ERP 的 Web 应用程序，并且正在实现一个像您一样的 CRUD 功能模式。我在 Laravel 中将我的资源 API 制作成了一个服务器端处理应用程序。好吧，请注意我已经将 @extends(layout.app) 和 @section('stylesheet') 部分删掉以直接进入答案。您应该在自己的应用程序中扩展它们以使一切正常。

View.blade 脚本

        <script>
            $(document).ready(function() {
                $.ajaxSetup({
                    headers: {
                        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
                    }
                });

    var table = $('#customertable').DataTable({
                    processing: true,
                    serverSide: true,
                    dom: 'B<"top"frli>tp',

                    columns: [
                        {data: 'id'}, //data refers to DB column name
                        {data: 'name'},

                        {data: 'action'}, //this is an addColumn item from Controller
                    ]

模型（选择 A.）$guarded = [] 或 B.）$fillable = ['fields','fields'] 随心所欲）

   class Customer extends Model
    {
        protected $fillable = ['name','chiname','type'];
    }

web.api（路由设置）

Route::resource('customer', 'CustomerController')->middleware('auth');

迁移/数据库模式结构

class CreateCustomersTable extends Migration
{
    public function up()
    {
        Schema::create('customers', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string('name');
            $table->string('chiname');
            $table->string('type');
            $table->timestamps();
        });
   }

    public function down()
    {
        Schema::dropIfExists('customers');
    }

我没有在其中加入任何保护措施，例如 gate、auth 等。但基本上这是在 Laravel 框架中使用 dataTable 与 JS，Ajax，Jquery，PHP 合而为一的框架。请注意，此类 CRUD 操作的查询直接链接到数据库服务器。如果您想显示 DataTable 处理的数据，请使用您自己的 jquery 函数来获取并在模式上显示它们。我的回答不是最好的，但希望对你有帮助 >:)
