Parse a URL and return its components
Example 1
Running
1.parse_url('http://username:password@hostname/path?arg=value#anchor');
Could return
1.{scheme: 'http', host: 'hostname', user: 'username', pass: 'password', path: '/path', query: 'arg=value', fragment: 'anchor'}
function parse_url (str, component) {
// Parse a URL and return its components
//
// version: 901.2514
// discuss at: http://phpjs.org/functions/parse_url
// + original by: Steven Levithan (http://blog.stevenlevithan.com)
// + reimplemented by: Brett Zamir
// % note: Based on http://stevenlevithan.com/demo/parseuri/js/assets/parseuri.js
// % note: blog post at http://blog.stevenlevithan.com/archives/parseuri
// % note: demo at http://stevenlevithan.com/demo/parseuri/js/assets/parseuri.js
// % note: Does not replace invaild characters with '_' as in PHP, nor does it return false with
// % note: a seriously malformed URL.
// % note: Besides function name, is the same as parseUri besides the commented out portion
// % note: and the additional section following, as well as our allowing an extra slash after
// % note: the scheme/protocol (to allow file:/// as in PHP)
// * example 1: parse_url('http://username:password@hostname/path?arg=value#anchor');
// * returns 1: {scheme: 'http', host: 'hostname', user: 'username', pass: 'password', path: '/path', query: 'arg=value', fragment: 'anchor'}
