我正在尝试在 CodeIgniter 2.x 中执行简单的 JQuery AJAX 页面加载
它似乎在不同的网络浏览器中也有不同的响应。注意：这不是一个不正确的路径问题，页面工作和显示都很好，我使用了 base_url、realurl、手动输入绝对路径和手动输入相对路径，但没有一个能 100% 成功。有时我认为它是 .htaccess 文件，但如果是它，它就不能在所有浏览器中工作，而不仅仅是 1。
现在可以在以下浏览器中使用：
- 铬 - 不工作
- IE 9 - 作品
- 火狐 - 作品
- Safari - 作品
- 歌剧 - 作品
我已经为任何希望提供帮助的人在线放置了一个干净的 CI 测试站点/应用程序：演示（也可以在这里进行测试，尝试页面上列出的第 1,2 和 3 点并观察控制台输出）： http ://www.allforthecode.co .uk/dev/CodeigniterJQueryAJAXTest/
文件：
/application/controllers/test.php
/application/views/test.php (loaded in by test.php)
/application/controllers/advert/test2.php (loaded in by the test.php view via JQuery ajax)
/application/controllers/test_root.php (loaded in by the test.php view via JQuery ajax)
/application/views/advert/test2.php (loaded in by test2.php)
testapp/应用程序/控制器/test.php
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class test extends CI_Controller {
public function index()
{
$this->load->view('test');
}
}
?>

Hello I am loaded by JQuery AJAX
../ci.php
<?
echo("I am a php file echo test from outside of the Codeigniter test site");
?>
Chromes 网络结果为：
http://127.0.0.1/testapp/public/advert/test2 - Method:POST - Status: Failed
额外的
此代码适用于 Chrome 的唯一方法是
- 如果我在该项目的 CodeIgniter 框架之外使用 html 文件，则 JQuery AJAX 加载有效。有什么想法可以在所有其他浏览器（除 Chrome 之外）中使用吗？
和
- If I place the page which JQuery wants to load at the root of the CodeIgniter website. So "application/controllers/test.php" which loads "application/views/advert/test2.php" will work but "application/controllers/advert/test.php" will not? But works in all other browsers? Chrome status - 0
Anyone got any ideas?
Give it a try at http://www.allforthecode.co.uk/dev/CodeigniterJQueryAJAXTest/ and try points 1,2 & 3 listed on page and watch console outputs)
