// This function creates a new anchor element and uses location // properties (inherent) to get the desired URL data. Some String // operations are used (to normalize results across browsers). // Read => http://james.padolsey.com/javascript/parsing-urls-with-the-dom/ function parseURL(url) { var a = document.createElement('a'); a.href = url; return { source: url, protocol: a.protocol.replace(':', ''), host: a.hostname, port: a.port, query: a.search, params: (function() { var ret = {}, seg = a.search.replace(/^\?/, '').split('&'), len = seg.length, i = 0, s; for (; i < len; i++) { if (!seg[i]) { continue; } s = seg[i].split('='); ret[s[0]] = s[1]; } return ret; })(), file: (a.pathname.match(/\/([^\/?#]+)$/i) || [, ''])[1], hash: a.hash.replace('#', ''), path: a.pathname.replace(/^([^\/])/, '/$1'), relative: (a.href.match(/tps?:\/\/[^\/]+(.+)/) || [, ''])[1], segments: a.pathname.replace(/^\//, '').split('/') }; }Penggunaan
Data yang diparse nantinya akan bermetamorfosis objek menyerupai ini:
{ source: "XXX", protocol: "XXX", host: "XXX", port: "XXX", query: "XXX", params: { "XXX": "XXX", "XXX": "XXX", "XXX": "XXX", "XXX": "XXX" }, file: "XXX", hash: "XXX", path: "XXX", relative: "XXX", segments: ["XXX", "XXX", "XXX"] }Dari situ kita dapat memanggil setiap bab dari objek yang dihasilkan dengan cara yang sama menyerupai ketika kita memanggil data pada objek. Misalnya:
var myUrl = parseURL('http://abc.com:8080/dir/index.html?id=255&m=hello#top'); alert(myUrl.protocol); // => akan menghasilkan `http`Selengkapnya
myUrl.file; // = 'index.html' myUrl.hash; // = 'top' myUrl.host; // = 'abc.com' myUrl.query; // = '?id=255&m=hello' myUrl.params; // = Object = { id: 255, m: hello } myUrl.path; // = '/dir/index.html' myUrl.segments; // = Array = ['dir', 'index.html'] myUrl.port; // = '8080' myUrl.protocol; // = 'http' myUrl.source; // = 'http://abc.com:8080/dir/index.html?id=255&m=hello#top'Sumber: James Padolsey – Parsing URLs with the DOM!
