以下是我从https://gist.github.com/1847816复制的一个版本,但经过重写,以便于阅读和调试。将锚数据的值复制到另一个名为“result”的变量的目的是因为锚数据相当长,因此将有限数量的值复制到结果将有助于简化结果。
/**
* See: https://gist.github.com/1847816
* Parse a URI, returning an object similar to Location
* Usage: var uri = parseUri("hello?search#hash")
*/
function parseUri(url) {
var result = {};
var anchor = document.createElement('a');
anchor.href = url;
var keys = 'protocol hostname host pathname port search hash href'.split(' ');
for (var keyIndex in keys) {
var currentKey = keys[keyIndex];
result[currentKey] = anchor[currentKey];
}
result.toString = function() { return anchor.href; };
result.requestUri = result.pathname + result.search;
return result;
}
其他回答
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!
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"

它既适用于绝对url,也适用于相对url
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"
}
