我想要一个字符串
var a = "http://example.com/aa/bb/"
并将其处理为一个对象
a.hostname == "example.com"
和
a.pathname == "/aa/bb"

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"

function getLocation(href) {
var match = href.match(/^(https?\:)\/\/(([^:\/?#]*)(?:\:([0-9]+))?)([\/]{0,1}[^?#]*)(\?[^#]*|)(#.*|)$/);
return match && {
href: href,
protocol: match[1],
host: match[2],
hostname: match[3],
port: match[4],
pathname: match[5],
search: match[6],
hash: match[7]
}
}
-
getLocation("http://example.com/");
/*
{
"protocol": "http:",
"host": "example.com",
"hostname": "example.com",
"port": undefined,
"pathname": "/"
"search": "",
"hash": "",
}
*/
getLocation("http://example.com:3000/pathname/?search=test#hash");
/*
{
"protocol": "http:",
"host": "example.com:3000",
"hostname": "example.com",
"port": "3000",
"pathname": "/pathname/",
"search": "?search=test",
"hash": "#hash"
}
*/
这是正则表达式的细分
var reURLInformation = new RegExp([
'^(https?:)//', // protocol
'(([^:/?#]*)(?::([0-9]+))?)', // host (hostname and port)
'(/{0,1}[^?#]*)', // pathname
'(\\?[^#]*|)', // search
'(#.*|)$' // hash
].join(''));
var match = href.match(reURLInformation);
