Javascript“开发”和“生产”
原标题:Javascript "development" and "production

我正在Sinatra中开发一个简单的应用程序,它可以进行许多异步调用。在我的javascript代码中,我有一个变量,用于存储所有调用的域。我的问题是如何在每次发布应用程序时更改变量的值,例如:

var url = "http://localhost:9292"; //development

var url = "http://mysite.com" //production

I would like 到 au到mate this, 到 prevent errors in deployed application. Is it possible?

我曾想过在我的“视图”中使用ruby代码来做这件事,但不知道这是否很酷。

对不起我的英语。

谢谢

问题回答

也许您可以使用:

var url =  http://  + document.domain;

document.domain获取当前域的名称。

尝试使用:

window.location.port

这将获取当前网站的域端口;)
