Javascript Ajax没有返回正确的响应。拉维尔

我正在使用Laravel创建一个社交网站。我有一个页面，可以加载当前用户创建的所有帖子。我在每个帖子上都有一个评论部分。我正在使用ajax发布评论

这是我的密码

这是

注释框的视图。它包含一个部分，我在其中循环浏览每个注释并显示它们。最后是类型字段，因此用户可以发布新注释：

<div class="comment-box-container ajax-refresh">
  <div class="comment-box">
    @if ($type->comments)
      @foreach ($type->comments as $comment)

        <div class="user-comment-box">

          <div class="user-comment">
            <p class="comment">
<!-- starts off with users name in blue followed by their comment-->
              <span class="tag-user"><a href="{{ route('profile', $comment->owner->id) }}">{{ $comment->owner->first_name }}&nbsp;{{ $comment->owner->last_name }}</a>&nbsp;</span>{{ $comment->body }}
            </p>
<!-- Show when the user posted comments-->
          <div class="com-details">
            <div class="com-time-container">
              &nbsp;{{ $comment->created_at->diffForHumans() }} ·
            </div>
          </div>

        </div><!--user-comment end-->
      </div><!--user-comment-box end-->
    @endforeach
  @endif

<!--type box-->
  <div class="type-comment">
    <div class="type-box">
    {{ Form::open(['data-remote', 'route' => ['commentPost', $id], 'class' => 'comments_create-form']) }}
        {{ Form::hidden('user_id', $currentUser->id) }}
        {{ Form::hidden($idType, $id) }}
        {{--{{ Form::hidden('user_id', $currentUser->id) }}--}}
        {{ Form::textarea('body', null, ['class' =>'type-box d-light-solid-bg', 'placeholder' => 'Write a comment...', 'rows' => '1']) }}
    {{ Form::close() }}
    </div><!--type-box end-->
  </div><!--type-comment-->


</div><!--comment-box end-->

getFeedForUser（）
是这样的：

public function getFeedForUser(User $user)
    {
        // get a list of all the ids the user follows
        $userIds = $user->followedUsers()->lists('followed_id');
        // add in the current users posts as well
        $userIds[] = $user->id;
        // Resource is the posts
        return Resource::with('messages', 'media', 'user', 'videos', 'comments', 'locations')->whereIn('user_id', $userIds)->latest()->get();
    }

Resource
模型与注释具有关系。看起来是这样的：

class Resource extends Eloquent {

    public function comments()
    {
        return $this->hasMany('Duuer\Comments\Comment');
    }   
}

Route::post('post/{id}/comment', ['as' => 'commentPost', 'uses' => 'CommentsController@postComment']);

class CommentsController extends \BaseController {

use CommanderTrait;
/**
 * Leave a new comment
 * @return Response
 */
 public function postComment()
 {
     extract(Input::only('user_id', 'resource_id', 'body'));
     $this->execute(new PostCommentCommand($user_id, $resource_id, $body));

     return Redirect::back();
 }
public function deleteComment()
{
    $comment = new Comment;
    $user = Auth::user();
    $id = Input::only('id');
    $comment->where('user_id', $user->id)->where('id', $id)->first()->delete();
    return Redirect::back();
}
}

public function handle($command)
    {
        $comment = $this->postRepository->leaveComment($command->user_id, $command->resource_id, $command->body);

        return $comment;
    }

public function leaveComment($user_id, $resource_id, $body)
    {
        $comment = Comment::leavePostComment($resource_id, $body);

        User::findOrFail($user_id)->comments()->save($comment);

        return $comment;
    }

public static function leavePostComment($resource_id, $body)
    {
        return new static([
            'resource_id' => $resource_id,
            'body' => $body
        ]);
    }

将注释保存到DB的路径如下所示：

class Resource extends Eloquent {

    public function comments()
    {
        return $this->hasMany('Duuer\Comments\Comment');
    }   
}

Route::post('post/{id}/comment', ['as' => 'commentPost', 'uses' => 'CommentsController@postComment']);

class CommentsController extends \BaseController {

use CommanderTrait;
/**
 * Leave a new comment
 * @return Response
 */
 public function postComment()
 {
     extract(Input::only('user_id', 'resource_id', 'body'));
     $this->execute(new PostCommentCommand($user_id, $resource_id, $body));

     return Redirect::back();
 }
public function deleteComment()
{
    $comment = new Comment;
    $user = Auth::user();
    $id = Input::only('id');
    $comment->where('user_id', $user->id)->where('id', $id)->first()->delete();
    return Redirect::back();
}
}

public function handle($command)
    {
        $comment = $this->postRepository->leaveComment($command->user_id, $command->resource_id, $command->body);

        return $comment;
    }

public function leaveComment($user_id, $resource_id, $body)
    {
        $comment = Comment::leavePostComment($resource_id, $body);

        User::findOrFail($user_id)->comments()->save($comment);

        return $comment;
    }

public static function leavePostComment($resource_id, $body)
    {
        return new static([
            'resource_id' => $resource_id,
            'body' => $body
        ]);
    }

CommentsController
如下所示：

class Resource extends Eloquent {

    public function comments()
    {
        return $this->hasMany('Duuer\Comments\Comment');
    }   
}

Route::post('post/{id}/comment', ['as' => 'commentPost', 'uses' => 'CommentsController@postComment']);

class CommentsController extends \BaseController {

use CommanderTrait;
/**
 * Leave a new comment
 * @return Response
 */
 public function postComment()
 {
     extract(Input::only('user_id', 'resource_id', 'body'));
     $this->execute(new PostCommentCommand($user_id, $resource_id, $body));

     return Redirect::back();
 }
public function deleteComment()
{
    $comment = new Comment;
    $user = Auth::user();
    $id = Input::only('id');
    $comment->where('user_id', $user->id)->where('id', $id)->first()->delete();
    return Redirect::back();
}
}

public function handle($command)
    {
        $comment = $this->postRepository->leaveComment($command->user_id, $command->resource_id, $command->body);

        return $comment;
    }

public function leaveComment($user_id, $resource_id, $body)
    {
        $comment = Comment::leavePostComment($resource_id, $body);

        User::findOrFail($user_id)->comments()->save($comment);

        return $comment;
    }

public static function leavePostComment($resource_id, $body)
    {
        return new static([
            'resource_id' => $resource_id,
            'body' => $body
        ]);
    }

我使用的是命令总线，因此我的处理程序类如下所示：

class Resource extends Eloquent {

    public function comments()
    {
        return $this->hasMany('Duuer\Comments\Comment');
    }   
}

Route::post('post/{id}/comment', ['as' => 'commentPost', 'uses' => 'CommentsController@postComment']);

class CommentsController extends \BaseController {

use CommanderTrait;
/**
 * Leave a new comment
 * @return Response
 */
 public function postComment()
 {
     extract(Input::only('user_id', 'resource_id', 'body'));
     $this->execute(new PostCommentCommand($user_id, $resource_id, $body));

     return Redirect::back();
 }
public function deleteComment()
{
    $comment = new Comment;
    $user = Auth::user();
    $id = Input::only('id');
    $comment->where('user_id', $user->id)->where('id', $id)->first()->delete();
    return Redirect::back();
}
}

public function handle($command)
    {
        $comment = $this->postRepository->leaveComment($command->user_id, $command->resource_id, $command->body);

        return $comment;
    }

public function leaveComment($user_id, $resource_id, $body)
    {
        $comment = Comment::leavePostComment($resource_id, $body);

        User::findOrFail($user_id)->comments()->save($comment);

        return $comment;
    }

public static function leavePostComment($resource_id, $body)
    {
        return new static([
            'resource_id' => $resource_id,
            'body' => $body
        ]);
    }

该
leaveComment（）
方法如下所示：

class Resource extends Eloquent {

    public function comments()
    {
        return $this->hasMany('Duuer\Comments\Comment');
    }   
}

Route::post('post/{id}/comment', ['as' => 'commentPost', 'uses' => 'CommentsController@postComment']);

class CommentsController extends \BaseController {

use CommanderTrait;
/**
 * Leave a new comment
 * @return Response
 */
 public function postComment()
 {
     extract(Input::only('user_id', 'resource_id', 'body'));
     $this->execute(new PostCommentCommand($user_id, $resource_id, $body));

     return Redirect::back();
 }
public function deleteComment()
{
    $comment = new Comment;
    $user = Auth::user();
    $id = Input::only('id');
    $comment->where('user_id', $user->id)->where('id', $id)->first()->delete();
    return Redirect::back();
}
}

public function handle($command)
    {
        $comment = $this->postRepository->leaveComment($command->user_id, $command->resource_id, $command->body);

        return $comment;
    }

public function leaveComment($user_id, $resource_id, $body)
    {
        $comment = Comment::leavePostComment($resource_id, $body);

        User::findOrFail($user_id)->comments()->save($comment);

        return $comment;
    }

public static function leavePostComment($resource_id, $body)
    {
        return new static([
            'resource_id' => $resource_id,
            'body' => $body
        ]);
    }

注释模型中的
leavePostComment（）
方法如下所示：

class Resource extends Eloquent {

    public function comments()
    {
        return $this->hasMany('Duuer\Comments\Comment');
    }   
}

Route::post('post/{id}/comment', ['as' => 'commentPost', 'uses' => 'CommentsController@postComment']);

class CommentsController extends \BaseController {

use CommanderTrait;
/**
 * Leave a new comment
 * @return Response
 */
 public function postComment()
 {
     extract(Input::only('user_id', 'resource_id', 'body'));
     $this->execute(new PostCommentCommand($user_id, $resource_id, $body));

     return Redirect::back();
 }
public function deleteComment()
{
    $comment = new Comment;
    $user = Auth::user();
    $id = Input::only('id');
    $comment->where('user_id', $user->id)->where('id', $id)->first()->delete();
    return Redirect::back();
}
}

public function handle($command)
    {
        $comment = $this->postRepository->leaveComment($command->user_id, $command->resource_id, $command->body);

        return $comment;
    }

public function leaveComment($user_id, $resource_id, $body)
    {
        $comment = Comment::leavePostComment($resource_id, $body);

        User::findOrFail($user_id)->comments()->save($comment);

        return $comment;
    }

public static function leavePostComment($resource_id, $body)
    {
        return new static([
            'resource_id' => $resource_id,
            'body' => $body
        ]);
    }

您必须提交表单，但必须在输入/文本区域绑定keydown事件（最好是IMHO）

对于您的AJAX请求，我建议您只获取JSON，使用Laravel，您可以使用
if（request:：AJAX（））
只返回JSON而不是整个页面，然后，您只需将新消息附加到DOM中。
您能更详细地解释一下吗？我对Laravel很陌生，对JS甚至更新。我在问题中添加了控制器。如何将
if（Request:：ajax（））
添加到我的控制器中？只有在HTML和JSON请求都需要相同的URL时，才需要
if（Request:：ajax（））
，但也可以创建2个控制器方法，每个方法1个。看看这个：或者这个好例子：
