如何从当前页面使用JavaScript获取主机URL [英] How to get the host URL using JavaScript from the current page

问题描述

鉴于我在以下页面上:

http://www.webmail.com/pages/home.aspx

如何使用JavaScript检索主机名("http://www.webmail.com" )?

How can I retrieve the host name ("http://www.webmail.com") with JavaScript?

推荐答案

// will return the host name and port
var host = window.location.host; 

或可能

var host = window.location.protocol + "//" + window.location.host;

或者如果您喜欢串联

var protocol = location.protocol;
var slashes = protocol.concat("//");
var host = slashes.concat(window.location.host);

// or as you probably should do
var host = location.protocol.concat("//").concat(window.location.host);

// the above is the same as origin, e.g. "https://stackoverflow.com"
var host = window.location.origin;

如果您有或希望有自定义端口，请使用 window.location.host 而不是 window.location.hostname >

If you have or expect custom ports use window.location.host instead of window.location.hostname
