我想拿一根绳子

var a = "http://example.com/aa/bb/"

然后把它加工成一个物体

a.hostname == "example.com"

and

a.pathname == "/aa/bb"

第一个答案的简单破解

var getLocation = function(href=window.location.href) {
    var l = document.createElement("a");
    l.href = href;
    return l;
};

即使没有参数,也可以使用它来计算当前的主机名 getLocation()。Hostname将给出当前主机名

其他回答

var loc = window.location;  // => "http://example.com:3000/pathname/?search=test#hash"

返回当前turl。

如果你想传递你自己的字符串作为url(在IE11中不工作):

var loc = new URL("http://example.com:3000/pathname/?search=test#hash")

然后你可以这样解析它:

loc.protocol; // => "http:"
loc.host;     // => "example.com:3000"
loc.hostname; // => "example.com"
loc.port;     // => "3000"
loc.pathname; // => "/pathname/"
loc.hash;     // => "#hash"
loc.search;   // => "?search=test"

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

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!

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/

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"
