Laravel，ajax发布后更新字段

Question

我正在制作一个类似的小型系统。我已经成功地向我的数据库发送了一个ajax帖子，其中我用1增加了tblarticles。row.like现在在我发送ajax帖子的同一页面上，我想在每次ajax帖子之后更新该字段的值。现在我的问题是我需要刷新，然后才能看到 1 而不是标准的 0

阿贾克斯邮政

$.ajax({
    url:"articles" ,
    type: "post",
    data: {
        'user_id':userid[0].value,
        'article_id':articleid[0].value,
        'user_id_fk':useridarticle[0].value,
        '_token': token[0].value
    },
    success: function(data){
        console.log(data);
    }
});

看法article/index.blade.php

@foreach($articles as $article)

          <div class="work-container">
              <article class="work-item">
                  <a href="{{action('HomeController@showArticle', [$article->id, $article->title])}}" class="work-thumbnail">
                      <img src="/articlePics/{{$article->image}}" alt="work-item">
                  </a>
                  <div class="work-info">
                      <span class="user">{{$article->title}}</span>
                      <div class="actions">
                          <form id="actionForm" action="" method="post" role="form">
                              <input type="hidden" name="articleId" value="{{$article->id}}">
                              <input type="hidden" name="userIdFk" value="{{$article->user_id}}">
                              <input type="hidden" name="userID" value="{{Auth::id()}}">
                              <input type="submit" name="like" class="likeBtn" id="test" value="Like">
                              <input type="hidden" name="_token" value="<?php echo csrf_token(); ?>">
                          </form>
                          <span class="likes" name="currentLikes">{{$article->likes}}</span>
                      </div>

                  </div>
              </article>
          </div>
      @endforeach

控制器

if(Request::ajax()) {
        $data = Input::all();
        $user_id =  Auth::id();
        $article_id = Input::get('article_id');
        $user_id_fk = Input::get('user_id_fk');
        $results = DB::select( DB::raw("SELECT * FROM likes WHERE user_id = '$user_id' AND article_id = '$article_id'") );
        $likedOrNot = DB::table('likes')
                ->where('article_id', $article_id)
                ->where('user_id', $user_id)
                ->pluck('likes');

        $currentLikesDB = DB::table('articles')->where('id', $article_id)->pluck('likes');
        echo json_encode(['likesnumber' => $currentLikesDB]);

这是我想用 ajax 发布后发布的当前数据更改的最后一个跨度。

Answer 1

尝试：

在articlesecho 中类似的数字与json_encode.

$currentLikesDB = DB::table('likes')->where('article_id', $article_id)->first();
$likesnumber = $currentLikesDB->likes;
return json_encode(['likesnumber' => $likesnumber]);

然后是阿贾克斯：

$.ajax({
    url:"articles" ,
    type: "post",
    data: {
        'user_id':userid[0].value,
        'article_id':articleid[0].value,
        'user_id_fk':useridarticle[0].value,
        '_token': token[0].value
    },
    success: function(data){
        $('.likes').html(data.likesnumber);
    }
});
