[英]Ajax script not working on CakePhp form
所以我在add.ctp操作中有這段代碼,並且我希望它在提交此表單后再加載另一個div,但是由於CakePHP3和Ajax並不是我的新手,所以我不知道是什么使腳本無法正常工作,因此我的jQuery頁面工作正常,但腳本中的日志未顯示在控制台中。我可能遺漏了一些非常明顯的內容,但我要求您提供幫助。
<?php
echo $this->Form->create($article, ['id' => 'ajaxform']);
echo $this->Form->input('title',array('class'=`enter code here`>'form-control'));
echo $this->Form->input('body', ['rows' => '3','class'=>'form-control']);
echo '<p></p>';
echo $this->Form->button(__('Salvar artigo'),array('class'=>'btn btn-success', 'id' => 'butao'));
echo $this->Form->end();
?>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script type="text/javascript">
console.log("test");
$(document).ready(function(){
$('#butao').click(function(e){
console.log("teste2");
$("#ajaxform").submit();
e.preventDefault;
$(".content-wrapper").load("main #main");
});
$("#ajaxform").on('submit',function(e)
{
console.log("teste");
var postData = $(this).serializeArray();
var formURL = $(this).attr("action");
$.ajax(
{
url : formURL,
type: "POST",
data : postData,
success:function(data, textStatus, jqXHR)
{
$('#main').html(data);
//data: return data from server
},
error: function(jqXHR, textStatus, errorThrown)
{
//if fails
}
});
e.preventDefault(); //STOP default action
e.unbind(); //unbind. to stop multiple form submit.
});
$("#ajaxform").submit(); //Submit the FORM
});
</script>
ArticlesController:
public function add()
{
$article = $this->Articles->newEntity();
if ($this->request->is('post')) {
$article = $this->Articles->patchEntity($article, $this->request->getData());
// Added this line
$article->user_id = $this->Auth->user('id');
// You could also do the following
//$newData = ['user_id' => $this->Auth->user('id')];
//$article = $this->Articles->patchEntity($article, $newData);
if ($this->Articles->save($article)) {
$this->Flash->success(__('Your article has been saved.'));
return $this->redirect(['action' => 'main']);
}
$this->Flash->error(__('Unable to add your article.'));
}
$this->set('article', $article);
}
-編輯-我要添加的主頁代碼
<?php foreach ($articles as $article): ?>
<tr>
<td><?= $article->id ?></td>
<td>
<?= $this->Html->link($article->title, ['action' => 'view',
$article->id]) ?>
</td>
<td>
<?= $article->created->format(DATE_RFC850) ?>
</td>
<td>
<?= $this->Form->postLink(
'Apagar',
['action' => 'delete', $article->id],
['confirm' => 'Têm a certeza?','class'=>'btn-danger btn-sm'])
?>
<?= $this->Html->link('Editar', ['action' => 'edit', $article->id],array('class'=>'btn-warning btn-sm')) ?>
<?= $this->Html->link('Copiar', ['action' => 'copy', $article->id],array('class'=>'btn-warning btn-sm')) ?>
</td>
</tr>
<?php endforeach; ?>
</table>
</div>
<button id="add" class="btn btn-primary btn-xs">
<h6>Adicionar Artigo</h6>
<script
src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js">
</script>
<script>
$(document).ready(function(){
$('#add').click(function(){
$("#main").load("add #addctp");
});
});
</script>
</button>
您應該從控制器返回json。
為了那個原因:
在app/Config/routes.php
添加:
Router::extensions(['json']);
啟用json擴展名。
在您的控制器中添加:
public function initialize()
{
parent::initialize();
$this->loadComponent('RequestHandler');
}
以啟用對內容類型的自動視圖類切換。
更改$this->set('article', $article);
至:
$this->set(compact('article'));
$this->set('_serialize', ['article']);
如果您不需要在數據轉換為json/xml
之前進行任何自定義格式設置,則可以跳過為控制器操作定義視圖文件的過程。
現在,您可以請求具有json擴展名的ArticlesController::add()
,然后您的操作會將$article
序列化為json。
最后創建app/webroot/js/Articles.js
:
Articles = {
init: function () {
this.add();
},
add: function(){
$( "#ajaxform" ).submit(function( event ) {
var that = $(this),
data = that.serializeArray(),
formURL = $('#ajaxform').attr('action') + '.json';
event.preventDefault();
$.ajax(
{
url: formURL,
dataType: 'JSON',
type: 'POST',
data: data,
success: function(data,text,xhr)
{
console.log(data);
},
error: function()
{
},
complete: function ()
{
}
});
});
}
};
$(document).ready(function () {
Articles.init();
});
並在您看來包括:
<?= $this->Html->script('Articles', ['block' => true]); ?>
