角 3 2 ajax

Question

我正在尝试学习 kohana，但在使用 kohana+ajax 时遇到了问题，控制台告诉我关于整页+ print_r + name\phone 的 ajax 响应的响应，如果运行没有 kohana 的例子，只是 php+ajax ，一切正常

更新：

等待：姓名：$姓名，phone：$phone号码。

recieve(look console.log): 来自主模板的页面 + print_r+ ajax 和 name:undefined 的响应， phone：未定义。

这里是重现行为的代码：

Controller/example.php:

 <?php defined('SYSPATH') or die('No direct script access.');    
    class Controller_Example extends Controller_Common
    {
        public function action_index()
        {    
            $content = View::factory('/example/show')
                ->bind('example', $example)
                ->bind('errors', $errors);    
            if ($this->request->is_ajax()) {     
                if (isset($_POST["name"]) && isset($_POST["phonenumber"]) ) {    
                       $result = array(
                        'name' => $_POST["name"],
                        'phonenumber' => $_POST["phonenumber"]
                    );
                              print_r($result);                    
                            echo json_encode($result);                    
                }  
            }
            else        $this->template->content=$content;    
        }}

在 json_encode(); 之后添加 exit; // 由于未知原因，主模板已附加到 ajax 的答案并 exit; 修复它。

and result = response;=>result = jQuery.parseJSON(response); // 用于解码 ajax 答案
