使用带有laravel的ajax提交表单时，避免页面重新加载

本文介绍了使用带有laravel的ajax提交表单时，避免页面重新加载的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我完全不想尝试使用ajax而不是laravel处理表单提交以避免页面重新加载等。但它不起作用，我不知道为什么。我通过示例搜索了精彩的网页，但似乎没有什么对我有用。这是我能得到的最接近的。我的知识有限，但我的抱负很高。请花一点时间查看我的代码，因为我现在处于精神崩溃的边缘。

I'm completely stuck trying to process a form submit using ajax instead of laravel to avoid page reload etc. But it isn't working and I don't know why. I've searched the wonderful web going through example after example but nothing seems to be working for me. This is the closest I can get. My knowledge is limited but my ambitions are high. Please take a moment and look through my code, beacuse I'm at the edge of mental breakdown right now.

这是我的jquery：

Here is my jquery:

$(document).ready(function() { $('#ajax').submit(function(event){ $.ajax({ type: 'POST', url: 'comments', data: $('form#ajax').serialize(), dataType: 'json', }) .done(function(data) { console.log(data); }); event.preventDefault(); }); });

这是我在刀片视图中的表单：

And here is my form in blade view:

{{ Form::open(array('url'=>'comments', 'id' => 'ajax')) }} {{ Form::hidden('parent_id', null) }} {{ Form::hidden('author', Auth::user()->username) }} {{ Form::textarea('content', null, array('placeholder' => 'Enter your comment here:', 'onfocus' => 'this.placeholder=""')) }}<br/> {{ Form::submit('Comment', array('class'=>'submit')) }} {{ Form::close() }}

这是我的控制器：

public function createComment() { //fixa här så man inte kan kommentera tom kommentar $validate = array('content' => 'required'); $validator = Validator::make(Input::all(), $validate); if($validator->fails()) { return Redirect::to('comments')->withErrors($validator)->withInput(Input::all()); } else { $comment = new Comment(); $comment->parent_id = Input::get('parent_id'); $comment->author = Input::get('author'); $comment->content = Input::get('content'); $comment->save(); } } public function postComment() { if(Request::ajax()) { $this->createComment(); return Response::json(Input::all()); } } public function getCommentsAndForm() { $comments = Comment::orderBy('id')->get(); return View::make('comment')->with('comments', $comments); }

这是我的路线：

Route::get('comments', array('uses' => 'CommentController@getCommentsAndForm')); Route::post('comments', array('uses' => 'CommentController@postComment'));

当我提交表格时，它会消失并且不显示任何内容。如果我删除 if（Request :: ajax（）），评论会被发布，但表单仍然消失，而不是空页面我在JSON中获得发布的评论。当我重新加载页面时，评论显示为我想要的。 有什么问题？我究竟做错了什么？我只希望发布的评论显示在我的表单上方而不重新加载页面，是否有解决方案？

When I submit the form it dissapears and nothing displays. If I remove if(Request::ajax()) the comments get posted but the form still dissapears and instead of an empty page I get the posted comment in JSON. And when I reload the page the comments shows as I want to. What is the problem? What am I doing wrong? I only want the posted comment to display above my form without reloading the page, is there a solution?

推荐答案

$(document).ready(function() { $('#ajax').submit(function(event){ event.preventDefault(); $.ajax({ type: 'POST', url: 'comments', data: $('form#ajax').serialize(), dataType: 'json', }) .done(function(data) { console.log(data); }); //just to be sure its not submiting form return false; }); });

这里重要的是阻止表单提交。您可以尝试将提交更改为按钮。

the important here is to prevent form from submiting. You can try to change submit to button.
