Js解析浏览器路径的方法

方法如下：
function parseURL(url) {
   var a =  document.createElement(\'a\');
   //创建一个链接
   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(\'/\')
   };
}

使用方法如下：

var myURL = parseURL(\'http://abc.com:8080/dir/index.html?id=255&m=hello#top\');
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\'
