Question

我是Laravel的新手，并且构建了简单的AJAX函数，在控制台中看到“ hello”，但实际上并没有在Chrome中发出任何警报。有谁知道原因。感谢您的关注。

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
$(document).ready(function(){

    $(".myTestLink").click(function(){

        $.ajax({
            method: 'post',
            dataType: 'json',
            beforeSend: function (request) {
                    return request.setRequestHeader('X-CSRF-Token', $("meta[name='csrf-token']").attr('content'));
                },
            url: 'insert-ajax',
            success: function (data)
            {
                alert(data);
            }
        });

    });
});
</script>

routes / web.php

<?php

/*
|--------------------------------------------------------------------------
| Web Routes
|--------------------------------------------------------------------------
|
| Here is where you can register web routes for your application. These
| routes are loaded by the RouteServiceProvider within a group which
| contains the "web" middleware group. Now create something great!
|
*/

Route::get('/', function () {
    return view('index');
});

Route::post('/insert-ajax', 'myTestController@testingsomething');

myTestController.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

class myTestController extends Controller
{
    public function testingsomething()
    {
        return "hello";
    }
}

进行ajax调用时，将dataType: 'json',切换为dataType: 'text',。 Alert无法处理json响应。

可以在控制台中看到AJAX成功功能，但实际上并没有发出警报
