I have always done it with jsonp, by passing a callback b/c services return json, if call back is passed then it will wrap all json in callback else they will simple return json.
我一直用 jsonp 来完成它，通过传递一个回调 b/c 服务返回 json，如果回调被传递，那么它会将所有 json 包装在回调中，否则它们将简单地返回 json。
But in your case

Without modifying a bit the server side there is not much you can do. The general policy is to not to allow cross domain requests.
如果不稍微修改服务器端，您无能为力。一般策略是不允许跨域请求。
There are few things worth mentioning though:
不过有几件事值得一提：
- Try changing the server side so it will support JSONP.
- If the HTTP response contains
Access-Control-Allow-Originheader then you can communicate with it with normal AJAX. This feature is supported in modern browsers only. Check this outfor more info. - You can do the cross domain requests with Flash and/or WebSockets. However server does have to support them.
- 尝试更改服务器端，使其支持 JSONP。
- 如果 HTTP 响应包含
Access-Control-Allow-Origin标头，那么您可以使用普通的 AJAX 与其通信。此功能仅在现代浏览器中受支持。查看此了解更多信息。 - 您可以使用 Flash 和/或 WebSockets 进行跨域请求。但是服务器确实必须支持它们。

Don't know what type application you are developing. But in ASP.NET you can do it by using a proxy page
不知道您正在开发什么类型的应用程序。但是在 ASP.NET 中，您可以通过使用代理页面来实现
