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"

现代方式:
new URL("http://example.com/aa/bb/")
返回一个具有主机名和路径名等属性的对象。
第一个参数是相对或绝对URL;如果它是相对的,那么你需要指定第二个参数(基本URL)。例如,对于相对于当前页面的URL:
new URL("/aa/bb/", location)
除了浏览器,这个API在Node.js中也可以通过require('url'). url从v7开始使用。
在acdcjunior解决方案上扩展了“searchParam”功能 模仿URL对象,增加了“searchParam”来解析查询字符串 适用于IE 6、7、8、9、10、11
用法- (JSFiddle Link)
// USAGE:
var myUrl = new ParsedUrl("http://www.example.com/path?var1=123&var2=abc#fragment");
console.log(myUrl);
console.log(myUrl.searchParam('var1'));
console.log(myUrl.searchParam('var2'));
输出- (JSFiddle链接)
{
hash: "#fragment",
host: "www.example.com:8080",
hostname: "www.example.com",
href: "http://www.example.com:8080/path?var1=123&var2=abc#fragment",
pathname: "/path",
port: "80",
protocol: "http:",
search: "?var1=123&var2=abc"
}
"123"
"abc"
CODE - (JSFiddle Link)
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://www.example.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;
//search Params
this.searchParam = function(variable) {
var query = (this.search.indexOf('?') === 0) ? this.search.substr(1) : this.search;
var vars = query.split('&');
for (var i = 0; i < vars.length; i++) {
var pair = vars[i].split('=');
if (decodeURIComponent(pair[0]) == variable) {
return decodeURIComponent(pair[1]);
}
}
console.log('Query variable %s not found', variable);
return '';
};
}
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;
}
当然,在>2016年,正确的答案是使用URL API 对于页面URL window.location And for <a href="…""> html lanchorelement API
也支持旧浏览器,使用polyfill:
<script crossorigin="anonymous" src="https://polyfill.io/v3/polyfill.min.js?features=URL"></script>
但作为另一种选择,它可以通过RegEx模式简单而准确地处理:
function URIinfo(s) { s=s.match(/^(([^/]*?:)\/*((?:([^:]+):([^@]+)@)?([^/:]{2,}|\[[\w:]+])(:\d*)?(?=\/|$))?)?((.*?\/)?(([^/]*?)(\.[^/.]+?)?))(\?.*?)?(#.*)?$/); return {origin:s[1],protocol:s[2],host:s[3],username:s[4],password:s[5],hostname:s[6],port:s[7],path:s[8],folders:s[9],file:s[10],filename:s[11],fileext:s[12],search:s[13],hash:s[14]}; } var sample='http://user:password@my.site.com:8080/onefolder/folder.name/file.min.js?query=http://my.site.com:8080/file.exe#hash-root:/file/1.txt'; console.log (URIinfo(sample)); /* { "origin": "http://user:password@my.site.com:8080", "protocol": "http:", "host": "user:password@my.site.com:8080", "username": "user", "password": "password", "hostname": "my.site.com", "port": ":8080", "path": "/onefolder/folder.name/file.min.js", "folders": "/onefolder/folder.name/", "file": "file.min.js", "filename": "file.min", "fileext": ".js", "search": "?query=http://my.site.com:8080/file.exe", "hash": "#hash-root:/file/1.txt" } */
使用正则表达式
任何形式的
绝对/相对路径 IPv4 / IPv6 网络协议/本地文件 查询/散列
返回所有URL选项,但不返回searchParams
(+)也将返回文件信息,如PHP pathInfo
