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/

对于那些正在寻找在IE, Firefox和Chrome中工作的现代解决方案的人:
这些使用超链接元素的解决方案都不会在chrome中起同样的作用。如果你传递一个无效(或空白)的url给chrome,它总是会返回脚本被调用的主机。所以在IE中你会得到空白,而在Chrome中你会得到localhost(或其他什么)。
如果你试图看着推荐人,这是骗人的。你需要确保你返回的主机在原始url中,以处理这个问题:
function getHostNameFromUrl(url) {
// <summary>Parses the domain/host from a given url.</summary>
var a = document.createElement("a");
a.href = url;
// Handle chrome which will default to domain where script is called from if invalid
return url.indexOf(a.hostname) != -1 ? a.hostname : '';
}
别再白费力气了。使用https://github.com/medialize/URI.js/
var uri = new URI("http://example.org:80/foo/hello.html");
// get host
uri.host(); // returns string "example.org:80"
// set host
uri.host("example.org:80");
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
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);
跨浏览器的URL解析,围绕IE 6、7、8和9的相对路径问题工作:
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://domain.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;
}
使用方法(演示JSFiddle在这里):
var myUrl = new ParsedUrl("http://www.example.com:8080/path?query=123#fragment");
结果:
{
hash: "#fragment"
host: "www.example.com:8080"
hostname: "www.example.com"
href: "http://www.example.com:8080/path?query=123#fragment"
pathname: "/path"
port: "8080"
protocol: "http:"
search: "?query=123"
}
