ajax javascript php programmer programming

案例地址 http://www.cndf.com/order/price.php

首先我的目的是想要知道 能通过几个选项自动计算出价格的方法。 通过查看html,了解到是

<code><script type="text/javascript" src="./js/ajax.js"></script>
</code>
Copy after login
Copy after login

这个js文件的作用,我测试过,源网站离线是无法计算出结果的,必须是联网状态下。将这个网页下载到本地,对ajax.js使用原网站的绝对路径,然后也无法计算出结果。然后查看该js代码头文件有个api

<code>ESSAYBAR={
    'api':'./api.php',
    'order':null
};
</code>
Copy after login
Copy after login

将js离线下载下来对api.php使用绝对路径依然无法计算。 求诸位大神,这是什么原理,有没有解决方法。

api.php 是服务端脚本,会在服务端执行。正常情况下你下载不了的。

又没有CORS,ajax不能跨域,你下载到本地js怎么会有用?
在服务器端做请求吧
