Question

我试图将ajax成功回调输出到视图中：

控制器：

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;

class AjaxTestController extends Controller
{
    public function ajax()
    {
        $nomi  = array();

        $nomi[0]['name'] = "alex";
        $nomi[0]['surname'] = "zambonin";

        $nomi[1]['name'] = "ciccio";
        $nomi[1]['surname'] = "pasticcio";

        return view('testAjax')->with('nomi',$nomi);

    }
}

查看：

        <link rel="stylesheet" href="{{ URL::asset('assets/stylesheets/frontend.css') }}">

    </head>
    <body>
        @foreach ($nomi as $nome)
            {{ $nome['name'] }}<br/>
        @endforeach
    </body>

    <script src="{{ URL::asset('assets/javascript/frontend.js') }}"></script>
    <script>
        $.ajax({
            url: 'testajax',
            dataType: 'json',
            type: 'GET',
            success: function(data) {
                alert(data);
            }
        })
    </script>

</html>

我可以在html页面中正确显示json数据，但我不能在javascript警报中得到它。另外，我在firefox控制台上有404错误;请参阅此UInt64

如何让它发挥作用？谢谢亚历

您获得的是404，因为URL / testajax不存在。您需要先为此创建路线。然后来自控制器的响应需要是JSON响应，如下所示：

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Http\Requests;

class AjaxTestController extends Controller
{
    public function myFancyWebsite()
    {
        return view('testAjax');
    }

    public function ajaxResponse()
    {
        $nomi  = array();

        $nomi[0]['name'] = "alex";
        $nomi[0]['surname'] = "zambonin";

        $nomi[1]['name'] = "ciccio";
        $nomi[1]['surname'] = "pasticcio";

        return response()->json($nomi);
    }
}

现在你的ajax请求应该指向那个只返回JSON响应的方法。但是你需要先在routes.php中创建一个路由：

Route::get('somepage', 'AjaxTestController@myFancyWebsite');
Route::get('testajax', 'AjaxTestController@ajaxResponse');
