我有我的從頭構建PHP MVC的問題和AJAX在jQuery中的實現，其中表單發送文本數據，接收的數據在JS文件中包含在Dashboard類構造中;自定義PHP MVC和AJAX，JSON的問題JSON中的意外的令牌D
模型（dashboard_model.php）
<?php
class Dashboard_Model extends Model
{
function __construct()
{
# code...
parent::__construct();
}
function xhrInsert(){
$text = $_POST['text'];
$sth = $this->db->prepare('INSERT INTO data (text) VALUES (:text)');
$sth->execute(array(':text' => $text));
$data = array('text' => $text, 'id' => $this->db->lastInsertId());
print json_encode($data);
}
function xhrGetListings(){
$sth = $this->db->prepare('SELECT * FROM data');
$sth->setFetchMode(PDO::FETCH_ASSOC);
$sth->execute();
$data = $sth->fetchAll();
print json_encode($data);
}
function xhrDeleteListing(){
$id = $_POST['id'];
$sth = $this->db->prepare('DELETE FROM data WHERE id ="'.$id.'"');
$sth->execute();
}
}
?>
控制器（dashboard.php）
它要求它處理Ajax回調默認js文件渲染器。
<?php
class Dashboard extends Controller
{
function __construct()
{
# code...
parent::__construct();
Session::init();
$logged = Session::get('loggedin');
if($logged == false){
Session::destroy();
header('location: ../login');
exit;
}
$this->view->js = array('dashboard/js/default.js');
}
function index() {
$this->view->render('dashboard/index');
}
function logout() {
Session::destroy();
header('location: ../login');
exit;
}
function xhrInsert() // xml http request ajax
{
$this->model->xhrInsert();
}
function xhrGetListings(){
$this->model->xhrGetListings();
}
function xhrDeleteListing(){
$this->model->xhrDeleteListing();
}
}
?>
$(function() {
\t $.get('dashboard/xhrGetListings', function(o){
\t \t //console.log(o);
\t \t for (var i =0; i<o.length; i++)
\t \t {
\t \t \t $('#listInserts').append('s<div>'+o[i].text+'<a class="del" rel="'+ o[i].id +'" href="#">X</a></div>');
\t \t }
\t \t $('.del').click(function(){
\t \t \t delItem = $(this);
\t \t \t var id = $(this).attr('rel');
\t \t \t
\t \t \t $.post('dashboard/xhrDeleteListing', {'id': id}, function(o){
\t \t \t \t delItem.parent().remove();
\t \t \t }, 'json');
\t \t \t return false;
\t \t });
\t },'json');
\t $('#randomInsert').on('submit', function(){
\t \t var url = $(this).attr('action');
\t \t var data = $(this).serialize();
\t \t
\t \t console.log('data received : '+data);
\t \t
\t \t $.ajax({
\t \t \t url: url,
\t \t \t type: 'post',
\t \t \t data: data,
\t \t \t beforeSend : function(xhr){
\t \t \t \t console.log('before'+xhr);
\t \t \t },
\t \t \t success : function(data, status, xhr){
\t \t \t \t console.log(data);
\t \t \t \t $('#listInserts').append('<div>'+data.text+'<a class="del" rel="'+ data.id +'" href="#">X</a></div>');
\t \t \t },
\t \t \t error: function(xhr, status, error){
\t \t \t \t console.log('erreur ajax');
\t \t \t \t console.log('jqXHR =' + xhr + '|status='+status + '|error='+error);
\t \t \t },
\t \t \t complete: function(xhr, status){
\t \t \t \t console.log('complete xhr = ' + xhr + '|status=' + status);
\t \t \t },
\t \t \t statusCode : {
\t \t \t \t 404 : function() {
\t \t \t \t \t console.log('STATUSCODE : 404 Page not found');
\t \t \t \t }
\t \t \t }
\t \t });
\t \t return false;
\t });
});<br/>
<form id="randomInsert" action="<?PHP echo URL; ?>dashboard/xhrInsert" method="post">
\t <input type="text" name="text" />
\t <input type="submit" />
</form>
<div id="listInserts">
</div>看到的鉻顯影劑的結果是：
data received : text=qsdfq
default.js:35 before[object Object]
default.js:38 Dashboard Object
(
[view] => View Object
(
[js] => Array
(
[0] => dashboard/js/default.js
)
)
[model] => Dashboard_Model Object
(
[db] => Database Object
(
)
)
)
{"text":"qsdfq","id":"102"}
default.js:46 complete xhr = [object Object]|status=success
當然這是不希望的結果，因爲它顯示未定義並且它不拔出JSON數據即使我把JSON類型的數據放入jQuery中
在Chrome開發者工具的XHR迴應是：
Dashboard Object ([view] => View Object ([js] => Array ([0] => dashboard/js/default.js)) [model] => Dashboard_Model Object ([db] => Database Object ())) {"text":"qsdfq","id":"102"}
的主要問題似乎是與那些添加的東西：
Dashboard Object ([view] => View Object ([js] => Array ([0] => dashboard/js/default.js)) [model] => Dashboard_Model Object ([db] => Database Object ()))
在返回阿賈克斯結果的頂部是過程中的jQuery $.get或$.post，數據類型爲json！
