我正在为我的项目使用Laravel 4。我有一个帖子的“新闻源”。每个帖子都可以评论。当用户对帖子发表评论时,页面会重新加载,新评论会显示在评论框中。我怎么不希望整个页面重新加载。所以,我可以使用ajax提交帖子。我提交表单并阻止页面刷新。但是,现在我不知道如何在不手动刷新页面的情况下让评论显示在帖子上?
以下是发布评论的路线:
Route::post('post/{id}/comment', ['as' => 'commentPost', 'uses' => 'CommentsController@postComment']);
将此评论发布到数据库的控制器:
public function postComment()
{
extract(Input::only('user_id', 'resource_id', 'body'));
$this->execute(new PostCommentCommand($user_id, $resource_id, $body));
return Redirect::back();
}
我正在使用命令总线,最终将注释保存到数据库中,如下所示:
public function leaveComment($user_id, $resource_id, $body)
{
$comment = Comment::leavePostComment($resource_id, $body);
User::findOrFail($user_id)->comments()->save($comment);
return $comment;
}
评论模型:
public static function leavePostComment($resource_id, $body)
{
return new static([
'resource_id' => $resource_id,
'body' => $body
]);
}
这是加载评论框的视图(包含属于帖子的所有评论和用于发布新评论的类型框。当用户点击“输入/返回时,我使用JS发布评论“关键):
<div class="comment-box-container">
<div class="comment-box">
@if ($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 }} {{ $comment->owner->last_name }}</a> </span>{{ $comment->body }}
</p>
<!-- Show when the user posted comments-->
<div class="com-details">
<div class="com-time-container">
{{ $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-->
这是我的 Javascript :ajax:
(function(){
$('form[data-remote]').on('submit', function(e){
var form = $(this);
var method = form.find('input[name="_method"]').val() || 'POST';
var url = form.prop('action');
$.ajax({
type: method,
url: url,
data: form.serialize(),
success: function() {
** I DON'T KNOW WHAT TO PUT HERE TO MAKE THE
COMMENT-BOX RELOAD AND DISPLAY THE NEWLY
POSTED COMMENT **
}
});
e.preventDefault();
});
})();
请注意我是JavaScript的新手,甚至是Ajax的新手。任何帮助将不胜感激!!

有些事情:
$.ajax({
type: method,
url: url,
data: form.serialize(),
success: function(data) {
// use a temp wrapper element to workaround weak jQuery HTML parser
var tmp = $('<div>');
tmp.html(data);
// update the comment box with the new one
$('.comment-box').html(tmp.find('.comment-box').html());
// update the form (so it eventually shows validations errors)
// don't forget to empty it via PHP if the submission was
// successful
$('.type-box').html(tmp.find('.type-box').html());
tmp.destroy();
}
});
