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"
当前回答
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
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
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
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"
