在ajax请求Laravel之后显示flash和错误消息

Question

在成功的ajax请求之后,我想向我的视图发送一条flash消息(例如,在编辑时,我想将用户重定向到主页,其中$ flash ="您的商店已经更新").在控制器中,它很容易,但我不知道在JavaScript中做什么.你们中的任何人都知道如何解决这个问题吗？我正在使用Laravel

调节器

   public function postUpdate (Request $request)
    {
            $this->validate($request, [
                'website_name' => 'required',
                'website_url' => 'required',
                'category' => 'required',
                'type' => 'required',
                'sells' => 'required',
                'location' => 'required',
                'description' => 'required',
                'payment' => 'required'
            ]);
            Shop::where('username', '=', Auth::user()->username)->update(['website_name' => Input::get('website_name'),
                'website_url' => Input::get('website_url'), 'type' => Input::get('type'), 'category' => Input::get('category'), 'sells' => Input::get('sells'), 'location' => Input::get('location'),
                'payment' => Input::get('payment'), 'description' => Input::get('description')]);
        return Response::json(['message' => 'Success', 'message_class' => 'alert alert-success fade in']);
    }

AJAX

$(".update-form").submit(function(s){

            s.preventDefault();

            var website_name = $('input[name=website_name]').val();
            var website_url = $('input[name=website_url]').val();
            var type = $('#type option:selected').val();
            var category = $('#category option:selected').val();
            var sells = $('input[name=sells]').val();
            var location = $('input[name=location]').val();
            var payment = $('input[name=payment]').val();
            var description = $("textarea#message").val();

                $.ajax({
                type: "POST",
                url: "advertiser/update",
                data: {
                    _token: token, website_name: website_name, website_url: website_url, type: type, category: category, sells: sells, location: location, payment: payment, description: description

                },

                success: function() {
                   $('.modal-backdrop').remove();
                    $('body').load('advertiser')

                },

                error: function(data) {
                    $('body').load('advertiser')

                }
                      })


        });

HTML

  <div class="row" id="errors">
            @if (Session::has('message'))
                <div class="{!! Session::get('message_class') !!}">
                    <a href="#" class="close" data-dismiss="alert">&times;</a>
                    <strong>Note!</strong> {!! Session::get('message') !!}
                </div>
            @endif

            @if($errors->has())
                <div class="alert alert-danger fade in">
                    <a href="#" class="close" data-dismiss="alert">&times;</a>

                    <p>the following errors have occured:</p>
                    <ul>
                        @foreach($errors->all() as $error)
                            <li>{{$error}}</li>
                        @endforeach
                    </ul>
                </div>

            @endif

如果使用 ajax 请求，则无法重定向控制器内。

但你可以这样做。

像这样在控制器中发送一些参数

$Response   = array(
            'success' => '1',
        );

或者

$Response   = array(
            'success' => '0',
            'error' => 'Your Flash Message'
        );

并返回它return $Response;

然后，在 ajax 结果中，您可以像这样重定向用户

if (data.success == 1){
    window.location = 'toyourdesiredpath';
}
else
{
//show your error message in your div or span
}
