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('/')
 };
}

下面是测试：

parseURL("https://www.baidu.com/s?wd=Kerkee&rsv_spt=1&rsv_iqid=0xd467cc9900022483&issp=1&f=8&rsv_bp=0&rsv_idx=2&ie=utf-8&tn=baiduhome_pg&rsv_enter=1&rsv_sug3=2&rsv_sug1=1&rsv_sug7=001&rsv_n=2")

 结果:

    "source" : "https://www.baidu.com/s?wd=Kerkee&rsv_spt=1&rsv_iqid=0xd467cc9900022483&iss…f-8&tn=baiduhome_pg&rsv_enter=1&rsv_sug3=2&rsv_sug1=1&rsv_sug7=001&rsv_n=2",
