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"

在这里找到:https://gist.github.com/jlong/2428561
var parser = document.createElement('a');
parser.href = "http://example.com:3000/pathname/?search=test#hash";
parser.protocol; // => "http:"
parser.host; // => "example.com:3000"
parser.hostname; // => "example.com"
parser.port; // => "3000"
parser.pathname; // => "/pathname/"
parser.hash; // => "#hash"
parser.search; // => "?search=test"
parser.origin; // => "http://example.com:3000"
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"
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);
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
怎么样?
'https://stackoverflow.com/questions/736513/how-do-i-parse-a-url-into-hostname-and-path-in-javascript'.split('//').pop() .split('/')[0]
结果:
“stackoverflow.com”
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...
