模型 Task.php 是

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Task extends Model
{
    protected $fillable = ['task', 'description','done'];
}

Ajax.js 是......

$(document).ready(function(){

var url = "/ajax-crud/public/tasks";

//display modal form for task editing
$('.open-modal').click(function(){
    var task_id = $(this).val();

    $.get(url + '/' + task_id, function (data) {
        //success data
        console.log(data);
        $('#task_id').val(data.id);
        $('#task').val(data.task);
        $('#description').val(data.description);
        $('#btn-save').val("update");

        $('#myModal').modal('show');
    })
});

//display modal form for creating new task
$('#btn-add').click(function(){
    $('#btn-save').val("add");
    $('#frmTasks').trigger("reset");
    $('#myModal').modal('show');
});

//delete task and remove it from list
$('.delete-task').click(function(){
    var task_id = $(this).val();

    $.ajax({

        type: "DELETE",
        url: url + '/' + task_id,
        success: function (data) {
            console.log(data);

            $("#task" + task_id).remove();
        },
        error: function (data) {
            console.log('Error:', data);
        }
    });
});

//create new task / update existing task
$("#btn-save").click(function (e) {
    $.ajaxSetup({
        headers: {
            'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')
        }
    })

    e.preventDefault();

    var formData = {
        task: $('#task').val(),
        description: $('#description').val(),
    }

    //used to determine the http verb to use [add=POST], [update=PUT]
    var state = $('#btn-save').val();

    var type = "POST"; //for creating new resource
    var task_id = $('#task_id').val();;
    var my_url = url;

    if (state == "update"){
        type = "PUT"; //for updating existing resource
        my_url += '/' + task_id;
    }

    console.log(formData);

    $.ajax({

        type: type,
        url: my_url,
        data: formData,
        dataType: 'json',
        success: function (data) {
            console.log(data);

            var task = '<tr id="task' + data.id + '"><td>' + data.id + '</td><td>' + data.task + '</td><td>' + data.description + '</td><td>' + data.created_at + '</td>';
            task += '<td><button class="btn btn-warning btn-xs btn-detail open-modal" value="' + data.id + '">Edit</button>';
            task += '<button class="btn btn-danger btn-xs btn-delete delete-task" value="' + data.id + '">Delete</button></td></tr>';

            if (state == "add"){ //if user added a new record
                $('#tasks-list').append(task);
            }else{ //if user updated an existing record

                $("#task" + task_id).replaceWith( task );
            }

            $('#frmTasks').trigger("reset");

            $('#myModal').modal('hide')
        },
        error: function (data) {
            console.log('Error:', data);
        }
    });
});
});

和 route.php 是

   <?php

Route::get('/', function () {
    $tasks = Task::all();

    return View::make('welcome')->with('tasks',$tasks);
});

Route::get('/tasks/{task_id?}',function($task_id){
    $task = Task::find($task_id);

    return Response::json($task);
});

Route::post('/tasks',function(Request $request){
    $task = Task::create($request->all());

    return Response::json($task);
});

Route::put('/tasks/{task_id?}',function(Request $request,$task_id){
    $task = Task::find($task_id);

    $task->task = $request->task;
    $task->description = $request->description;

    $task->save();

    return Response::json($task);
});

Route::delete('/tasks/{task_id?}',function($task_id){
    $task = Task::destroy($task_id);

    return Response::json($task);
});

任何人都可以告诉我为什么会收到错误。

您需要在 routes.php 的顶部导入任务类，如下所示：

<?php

use App\Task;

Route::get('/', function () {
    ...
...

在Laravel中创建了一个页面，用于获取，删除和添加功能。因为我正在使用Alax
