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/

只需使用url.js库(用于web和node.js)。

https://github.com/websanova/js-url

url: http://example.com?param=test#param=again

url('?param'); // test
url('#param'); // again
url('protocol'); // http
url('port'); // 80
url('domain'); // example.com
url('tld'); // com

etc...

在acdcjunior解决方案上扩展了“searchParam”功能 模仿URL对象，增加了“searchParam”来解析查询字符串 适用于IE 6、7、8、9、10、11

用法- (JSFiddle Link)

// USAGE:
var myUrl = new ParsedUrl("http://www.example.com/path?var1=123&var2=abc#fragment");
console.log(myUrl);
console.log(myUrl.searchParam('var1'));
console.log(myUrl.searchParam('var2'));

输出- (JSFiddle链接)

{
  hash: "#fragment",
  host: "www.example.com:8080",
  hostname: "www.example.com",
  href: "http://www.example.com:8080/path?var1=123&var2=abc#fragment",
  pathname: "/path",
  port: "80",
  protocol: "http:",
  search: "?var1=123&var2=abc"
}

"123"
"abc"

CODE - (JSFiddle Link)

function ParsedUrl(url) {
    var parser = document.createElement("a");
    parser.href = url;
    
    // IE 8 and 9 dont load the attributes "protocol" and "host" in case the source URL
    // is just a pathname, that is, "/example" and not "http://www.example.com/example".
    parser.href = parser.href;
    
    // IE 7 and 6 wont load "protocol" and "host" even with the above workaround,
    // so we take the protocol/host from window.location and place them manually
    if (parser.host === "") {
        var newProtocolAndHost = window.location.protocol + "//" + window.location.host;
        if (url.charAt(1) === "/") {
            parser.href = newProtocolAndHost + url;
        } else {
            // the regex gets everything up to the last "/"
            // /path/takesEverythingUpToAndIncludingTheLastForwardSlash/thisIsIgnored
            // "/" is inserted before because IE takes it of from pathname
            var currentFolder = ("/"+parser.pathname).match(/.*\//)[0];
            parser.href = newProtocolAndHost + currentFolder + url;
        }
    }
    
    // copies all the properties to this object
    var properties = ['host', 'hostname', 'hash', 'href', 'port', 'protocol', 'search'];
    for (var i = 0, n = properties.length; i < n; i++) {
      this[properties[i]] = parser[properties[i]];
    }
    
    // pathname is special because IE takes the "/" of the starting of pathname
    this.pathname = (parser.pathname.charAt(0) !== "/" ? "/" : "") + parser.pathname;
  
  //search Params
  this.searchParam =  function(variable) {
    var query = (this.search.indexOf('?') === 0) ? this.search.substr(1) : this.search;
    var vars = query.split('&');
    for (var i = 0; i < vars.length; i++) {
        var pair = vars[i].split('=');
        if (decodeURIComponent(pair[0]) == variable) {
            return decodeURIComponent(pair[1]);
        }
    }
    console.log('Query variable %s not found', variable);
    return '';
    };
}

js-uri(在谷歌Code上可用)接受字符串URL并从中解析URI对象:

var some_uri = new URI("http://www.example.com/foo/bar");

alert(some_uri.authority); // www.example.com
alert(some_uri);           // http://www.example.com/foo/bar

var blah      = new URI("blah");
var blah_full = blah.resolve(some_uri);
alert(blah_full);         // http://www.example.com/foo/blah

var getLocation = function(href) {
    var l = document.createElement("a");
    l.href = href;
    return l;
};
var l = getLocation("http://example.com/path");
console.debug(l.hostname)
>> "example.com"
console.debug(l.pathname)
>> "/path"

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!
