如何使用jQuery获取网络服务器时间?
How can I get the web-server time using jQuery?
推荐答案
这是一种在服务器端无需任何特定代码甚至没有有效路径的方法.
Here's a way that may work without any particular code, or even a valid path, on the server side.
try {
var date = new Date($.ajax({'type': 'HEAD', 'url': '/'}).getResponseHeader('Date'));
}
catch(err) {
var date = null;
}
这是假定服务器将始终返回"Date"标头.必须对服务器的细节进行一些试验.
This is presumptive that the server will always return a "Date" header. Some experimentation with the particulars of your server will be necessary.
要添加:请注意,这更像是一种讨人喜欢的hacky方式. 正确"的方法是设置服务器端脚本以快速返回服务器时间,或者可以将其内联到将要运行脚本的页面上,或者简单地使用客户端时间(如果为足够好."
EDIT TO ADD: Note that this is more of a cutesy hackish way to do this. The "correct" way would be to set up a server-side script to return the server time quickly, or possibly put it inline to the page where the script will be running, or simply use the client-side time if it would be "good enough."
