freddiefujiwara的答案很好,但我也需要在ie中支持相对url。我想出了以下解决方案:
function getLocation(href) {
var location = document.createElement("a");
location.href = href;
// IE doesn't populate all link properties when setting .href with a relative URL,
// however .href will return an absolute URL which then can be used on itself
// to populate these additional fields.
if (location.host == "") {
location.href = location.href;
}
return location;
};
现在使用它来获得所需的属性:
var a = getLocation('http://example.com/aa/bb/');
document.write(a.hostname);
document.write(a.pathname);
例子:
function getLocation(href) { var location = document.createElement("a"); location.href = href; // IE doesn't populate all link properties when setting .href with a relative URL, // however .href will return an absolute URL which then can be used on itself // to populate these additional fields. if (location.host == "") { location.href = location.href; } return location; }; var urlToParse = 'http://example.com/aa/bb/', a = getLocation(urlToParse); document.write('Absolute URL: ' + urlToParse); document.write('<br />'); document.write('Hostname: ' + a.hostname); document.write('<br />'); document.write('Pathname: ' + a.pathname);
其他回答
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"
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 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
这不会解析查询和散列,但除此之外它工作得很好。
const getURIParts = (url) => { const matches = url.match(/^(\w+?:\/\/)?([\w-\.]+(?=\/?))?:?(\d*)?([^:]*)/) return { scheme: matches ? matches[1] : undefined, host: matches ? matches[2] : '', port: matches ? matches[3] : undefined, pathname: matches ? matches[4] : '' } } console.log(getURIParts("")) console.log(getURIParts("http://localhost/bla")) console.log(getURIParts("https://api.spotify.com/")) console.log(getURIParts("https://api.spotify.com")) console.log(getURIParts("wss://wss.slack.com/link/?ticket=1234-5678")) console.log(getURIParts("localhost")) console.log(getURIParts("localhost/bla")) console.log(getURIParts("localhost/")) console.log(getURIParts("api.spotify.com/bla/two")) console.log(getURIParts("api.spotify.com:8000/bla/two")) console.log(getURIParts("https://api.spotify.com:8800/")) console.log(getURIParts("/mp3-preview/f504e6b8e037771318656394f532dede4f9bcaea"))
