用ajax显示模态-Laravel

Question

I would like to display the content of my route in a modal. To do this, I call the modal with the button and want to load the data via ajax in the modal. I always get the error message: Undefined variable: tasks I have included the modal in the index page, because otherwise I can not rouse it with the button. Where is the mistake?

Button

<li><a href="{{route('todolists.show', $list->id)}}" id="show-task-modal" class="btn btn-success btn-xs white hover-hidden">
                                        <i class="fa fa-plus"></i> Erstellen
                                    </a>
                                </li>

Controller

   public function show($id)
{
    $todolists = Todolists::find($id);
    $tasks = $todolists->tasks()->orderBy('created_at', 'dsc')->get();

    return view('elements.addTask', compact('tasks'));
}

route

Route::get('/tasks/{id}', 'Admin\TaskController@show')->name('todolists.show');

function

$(document).ready(function () {
      $('body').on('click', '#show-task-modal', function(event) {
                event.preventDefault();

                    var anchor = $(this),
                            url = anchor.attr('href'),
                            title = anchor.data('title');

                        $("#task-modal-subtitle").text(title);

                        $.ajax({
                                url: url,
                            dataType: 'html',
                            success: function(response) {
                                $('#task-table-body').html(response);
                            },
                            error: function (data){
                                    console.log(data);
                            }
                    });

                    $('#task-modal').modal('show');
            });
        });

Modal

Answer 1

Your ajax call is returning a view with tasks. $tasks can only be used on that view.

Your ajax call should not return view. It should just return data in json format.

return response()->json(['tasks' => $tasks]);

Then use jquery to loop from tasks array and make html from it and place in modal.

OR

If you still want to return view with tasks from ajax then your modal should not contain foreach loop (remove it). It should contain that view that you are returning from controller (addTask) and that view should have foreach loop to render $tasks

<div> ..@include('addTasks') </div> //modal
