我需要从给定的URL中提取完整的协议、域和端口。例如:
https://localhost:8181/ContactUs-1.0/contact?lang=it&report_type=consumer
>>>
https://localhost:8181

首先获取当前地址
var url = window.location.href
然后解析这个字符串
var arr = url.split("/");
你的网址是:
var result = arr[0] + "//" + arr[2]
其他回答
var getBasePath = function(url) {
var r = ('' + url).match(/^(https?:)?\/\/[^/]+/i);
return r ? r[0] : '';
};
protocol属性设置或返回当前URL的协议,包括冒号(:)。
这意味着如果你只想获得HTTP/HTTPS部分,你可以这样做:
var protocol = window.location.protocol.replace(/:/g,'')
对于域名,您可以使用:
var domain = window.location.hostname;
对于您可以使用的端口:
var port = window.location.port;
请记住,如果端口在URL中不可见,则端口将是空字符串。例如:
http://example.com/将为端口返回“” http://example.com:80/将返回80端口
如果在没有端口使用时需要显示80/443
var port = window.location.port || (protocol === 'https' ? '443' : '80');
使用ES6模板文字:
Const url = ' ${location.protocol}//${location.hostname}${location.port?':'+location.port: "} '; . getelementbyid(“结果”)。innerText = url; < div id = "结果" > < / div >
你可以简化为:
Const url = ' ${location.protocol}//${location.host} '; . getelementbyid(“结果”)。innerText = url; < div id = "结果" > < / div >
ES6风格,具有可配置参数。

export const getCurrentBaseURL = (includeProtocol = true, removeTrailingSlash = false) => {
if (!window || !window.location || !window.location.hostname || !window.location.protocol) {
console.error(
`The getCurrentBaseURL function must be called from a context in which window object exists. Yet, window is ${window}`,
[window, window.location, window.location.hostname, window.location.protocol],
)
throw new TypeError('Whole or part of window is not defined.')
}
const URL = `${includeProtocol ? `${window.location.protocol}//` : ''}${window.location.hostname}${
window.location.port ? `:${window.location.port}` : ''
}${removeTrailingSlash ? '' : '/'}`
// console.log(`The URL is ${URL}`)
return URL
}
正如已经提到的,有一个尚未完全支持的window.location.origin,但不是使用它或创建一个新变量来使用,我更喜欢检查它,如果它没有设置为设置它。
例如;
if (!window.location.origin) {
window.location.origin = window.location.protocol + "//" + window.location.hostname + (window.location.port ? ':' + window.location.port: '');
}
实际上我在几个月前写过关于window.location.origin的修复
