Discussion on JS's URL analytic function Encapsulation _javascript skill

In actual development, some of the data through the get way with the background, the need to use the data in the URL, so we need to obtain the URL useful information, the following encapsulated functions can be resolved to the URL is very thorough, you can take direct use of:

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;//len = 2
          alert (a.search) 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 ('/')
    };
  

The use of this function is as follows:

var myurl = parseURL (window.location.href); Through the parseURL function to resolve the current page url;window.location.href can be replaced by any URL to parse, if you write the other URL directly, the format should be string;
var search_obj =　　Myurl.params;　　The Analytic method is to resolve the content of search to the object, to facilitate the call of data, and other methods can be tried by themselves;
var url_post = myurl.post; The port number of the current page;

The above is small series for everyone to talk about JS URL analytic function Package All content, I hope we support cloud Habitat Community ~
