今天我遇到了这个问题，我发现:URL - MDN Web api

var url = new URL("http://test.example.com/dir/subdir/file.html#hash");

这返回:

{ hash:"#hash", host:"test.example.com", hostname:"test.example.com", href:"http://test.example.com/dir/subdir/file.html#hash", origin:"http://test.example.com", password:"", pathname:"/dir/subdir/file.html", port:"", protocol:"http:", search: "", username: "" }

希望我的第一篇文章能帮助到你!

下面是一个使用regexp的简单函数，它模仿了a标记行为。

Pros

可预测的行为(无跨浏览器问题) 不需要DOM 它真的很短。

Cons

regexp有点难读

-

function getLocation(href) {
    var match = href.match(/^(https?\:)\/\/(([^:\/?#]*)(?:\:([0-9]+))?)([\/]{0,1}[^?#]*)(\?[^#]*|)(#.*|)$/);
    return match && {
        href: href,
        protocol: match[1],
        host: match[2],
        hostname: match[3],
        port: match[4],
        pathname: match[5],
        search: match[6],
        hash: match[7]
    }
}

-

getLocation("http://example.com/");
/*
{
    "protocol": "http:",
    "host": "example.com",
    "hostname": "example.com",
    "port": undefined,
    "pathname": "/"
    "search": "",
    "hash": "",
}
*/

getLocation("http://example.com:3000/pathname/?search=test#hash");
/*
{
    "protocol": "http:",
    "host": "example.com:3000",
    "hostname": "example.com",
    "port": "3000",
    "pathname": "/pathname/",
    "search": "?search=test",
    "hash": "#hash"
}
*/

编辑:

下面是正则表达式的分解

var reURLInformation = new RegExp([
    '^(https?:)//', // protocol
    '(([^:/?#]*)(?::([0-9]+))?)', // host (hostname and port)
    '(/{0,1}[^?#]*)', // pathname
    '(\\?[^#]*|)', // search
    '(#.*|)$' // hash
].join(''));
var match = href.match(reURLInformation);

你也可以使用来自Locutus项目(前php.js)的parse_url()函数。

代码:

parse_url('http://username:password@hostname/path?arg=value#anchor');

结果:

{
  scheme: 'http',
  host: 'hostname',
  user: 'username',
  pass: 'password',
  path: '/path',
  query: 'arg=value',
  fragment: 'anchor'
}

试试这个:

函数getUrlPath (str) { //fakepath当url没有路径 var fakepath = "/FakPath"; Var url = str+fakepath; Var reg = /.+?\:\/\/.+?(\/.+?)(?:#|\?|$)/; Var output = reg.exec(url); //检查"output" != null 返回(输出)?输出[1].replace(fakepath，""): fakepath; ｝ Var myurl = "https://stackoverflow.com/questions/736513/"; const path = getUrlPath(myurl); Console.log (path); //output: /questions/736513/

那么简单的正则表达式呢?

url = "http://www.example.com/path/to/somwhere";
urlParts = /^(?:\w+\:\/\/)?([^\/]+)(.*)$/.exec(url);
hostname = urlParts[1]; // www.example.com
path = urlParts[2]; // /path/to/somwhere

今天我遇到了这个问题，我发现:URL - MDN Web api

var url = new URL("http://test.example.com/dir/subdir/file.html#hash");

这返回:

{ hash:"#hash", host:"test.example.com", hostname:"test.example.com", href:"http://test.example.com/dir/subdir/file.html#hash", origin:"http://test.example.com", password:"", pathname:"/dir/subdir/file.html", port:"", protocol:"http:", search: "", username: "" }
