Question

我无法弄清楚为什么JSON不在我的评论系统中工作。任何帮助将不胜感激。

目前，当我提交评论表单时，ajax-loader会闪烁并旋转，但评论不会加载，我会得到＆＃34;意外标记＆＃34;语法错误。当我刷新页面时，会显示评论。

这是我的AJAX事件处理程序，它直接进入我的控制器（代码片段后面）：

($('document').ready(function(){
    $("button.submit").bind('click', function (e){
        e.preventDefault();

        var form = $('form');
        var submit = $('button#submit');

            $("#flash").show();
            $("#flash").fadeIn(400).html('<img src="/img/ajax-loader.gif" />');

        $.ajax({
            type: 'POST',
            cache: false,
            url: '?comment='+comment+'&item='+item+'&author='+author+'&rating='+rating,
            data: form.serialize(),
            dataTYPE: 'json',
            success: function( data ){

                comment_insert( jQuery.parseJSON( data ) );
                console.log( "ResponseText: " +data );

                form.trigger('reset');

                $("#flash").hide();

            }
        });

    });
});

function comment_insert( data )
{
    var insert = '';
    insert += '<article>';
    insert += '<p>';
    insert += ''+data.comment+'';
    insert += '&mdash;';
    insert += ''+data.author+'';
    insert += ' | <a href="/item/reply"> Reply</a>';
    insert += '</p>';
    insert += '</article>';

    $('.comment_block').prepend( insert );
}

控制器：

 if($this->request->is('post')) {
            $comments = ItemComments::create($this->request->data);
            $comments->author_id = $this->user->id;

            $comments->comment = $this->request->data['comment'];
            $comments->item_id = $this->request->data['item'];
            $comments->author_id = $this->request->data['author'];
            $comments->rating = $this->request->data['rating'];
            $comments->save();

            echo json_encode($comments);

        }

查看页面：

<div class="col-lg-12">
    <h4>Comments and questions:</h4>

        <?php if (count($comments)): foreach ($comments as $feedback): ?>
        <article>
            <p>
            <?=$feedback->comment?>
            &mdash;
            <a href="/users/<?=$feedback->author->url?>">
                <?=$feedback->author->firstname?>
                <?=$feedback->author->lastname?>
                <?=$feedback->id?>
            </a>|
            <a href="/item/reply">Reply</a>
            </p>
        </article>
        <?php endforeach;?>

        <?php else: ?>

            <div class="col-lg-12">
                <div class="well-sm text-center">
                    <i class="fa fa-comments fa-2x"></i>
                    <h4>No comments yet.</h4>
                </div>
            </div>

        <?php endif; ?>

    <div class="comment_block"></div>
    <div id="flash"></div>

</div>
